    The advantage of the system is the very simple construction and that the carbon dioxide is being scrubbed out effectively At the moment the breathing volume is increased because of the metabolic consumption of the oxygen content the diver simply inject more oxygen by means of a hand injector 5 There are also systems supplied with a constant mass valve who feed approx 1 5 2 ltr oxygen to the

  • Evolution of a Dolphin rebreather
    facing the same direction I designed and built 2x tank mounts to bolt onto the shell of my Dolphin The first ones were stainless steel but later on I used aluminum and shortened scuba tank straps along with a proper carry handle on the back The original handle will in time crack your shell Below is a photo of the shell setup for the two cylinders and the handle that comes in so handy Next I added 2x Poseidon first stage regulators with din fittings and o2 cleaned both They were Cyclon 5000 units and I used the first stages only One for dilutant and the other for 02 and oxygen cleaned one of the cylinders and labeled it accordingly I then designed the dilutant addition by using the existing demand valve as it was already there so might as well use it keep it simple principle I found that the spring in the bypass valve was designed for 16 bar line pressure and I was using 8 5 bar so it was replaced with the spring from the demand valve of a US divers Conshelf SE regulator and this worked extremely well I could crack the demand valve with ease no matter how fast or slow I descended The contents gauge for the dilutant is over the shoulder and clips to the D ring on right hand side of the harness I also took an air feed from the dilutant first stage and brought the hose over the shoulder and across to the left hand side and used an Air2 as a bailout and for BC inflation This works very well and has never needed to be changed since OXYGEN INJECTION I designed the o2 injection using a Clippard Minimatics two port upstream valve and o2 cleaned it To this I added a Swage lock needle valve and instead of using brass fittings to plumb it into the bypass valve ported it directly through the body of the Clippard valve block This made for a nice neat package enabling good control of the injection of oxygen into the breathing loop The needle valve had a flow rate of 0 5 liters per minute and I found that controlling the flow rate of oxygen was very easy The two main parts now used are the Clippard Minimatics MJV 2 manual bypass valve and the Swagelock fine metering valve B SM2 S2 A I put this between the Poseidon first stage regulator and the Dosing block My dive buddy Frank Feather machined a small flow restrictor and plumbed it into the dosing block The Flow rate at 8 5 bar IP pressure was around 8 liters per minute this was ample flow for a manual rebreather It would take approx one minute to fully flush the loop so I would have plenty of time to fly the rig on the tank valve if for some reason the manual Oxygen addition valve started to leak past the seat If you look on

    Culotta for searching and finding this information A PLSS portable life support subsystem performs the following functions Provides breathing oxygen and controls the pressure of the crewmember s suit Provides thermal control by cooling and recirculating both the oxygen in the suit and the water in the Liquid Cooling Ventilation Garment LCVG Removes humidity odours carbon dioxide and other contaminants from the recirculating oxygen Provides communications for the suited crewmembers Provides sensing of important system parameters The PLSS includes oxygen bottles water storage tanks a sublimator a fan separator pump motor assembly a contaminant control cartridge various regulators valves and sensors communications and the microprocessor caution and warning system module System ventilation airflow enters the suit from the PLSS at the helmet and flows from behind the head over the face and down through the suit Oxygen carbon dioxide and water vapour from breathing leave the suit through the liquid cooling and ventilation garment near the astronaut s elbows and feet and return to the PLSS The flow first goes through the PLSS contaminant control cartridge where activated charcoal and lithium hydroxide remove odours and carbon dioxide Next it passes through a fan that maintains a flow of about six cubic feet per minute Gas flow is then routed to the sublimator a cooling device which condenses water vapour and permits its removal by a slurper and by the rotary separator The water that is removed from the gas flow is pumped primarily into the PLSS water storage tanks for reuse in cooling the astronaut The sublimator also cools the ventilation flow to about 12 C The oxygen then moves through a flow sensor and back to the suit inlet Oxygen is added as needed to the ventilation flow from the primary oxygen tanks entering the ventilation loop downstream of

  • PRISM rebreather
    a single battery is over forty hours The oxygen solenoid is outside of the breathing loop A simple on off switch allows the user to turn the unit off or on as desired at any time One of the unique features on the Topaz is a true secondary display This display is easy to read and allows the diver to check each sensor s status totally independent of any electronics or battery The secondary displays oxygen partial pressure levels for each sensor driven solely from the voltage outputted by the sensor itself This allows the Topaz to be operated easily with the electronics turned off and or no power available to the unit In fact electronics failure or loss of battery power is not a bailout situation with the Topaz because of this feature The secondary also displays battery voltage and unit set point The Topaz easily adapts to various cylinders sizes allows for use of a cover for increased hydrodynamics or flies equally well without it The unit has off board diluent bailout built in Of course the unit is bubble less unless the diver is ascending and provides release of expanding gas on ascent with a standard over pressure relief valve However most users simply exhale out of their nose for more intimate control of the process The Topaz is equally suited for recreational diving or technical diving For the recreational diver the unit offers long durations with optimized breathing mixtures all in a small package This allows for much longer durations at greater depths than available while diving open circuit within no stop limits Like all rebreathers the Topaz provides a warm and moist breathing mixture Plus it allows the diver a much quieter diving experience The lack of bubbles makes a huge difference when approaching or observing wildlife It is a real advantage to those divers that are looking to capture wildlife video or photos Researchers from the University of California at Davis have been utilizing the Topaz to tag hammerhead sharks in the Sea of Cortez Previous attempts at tagging using open circuit equipment proved completely unsuccessful The animals did not approach close enough to the researchers to even allow for an attempt at tagging The first time the researchers used the Topaz they were successful The United States Fish and Wildlife Service has been using the Topaz to conduct research on the California Sea Otter Video and film productions have used the Topaz to allow for the long durations and close approaches to wildlife needed to capture images for broadcast For the technical diver the unit adapts well to customization and adaptation for specific mission logistics and needs Many users have incorporated stainless steel backplates and harnesses into the unit The small size and long duration allow for the unit be easily staged or carried for long duration dives In fact the Topaz was recently used in a 20 000 plus feet 6 200 meter cave penetration in Australia Establishing a new world record

  • Jan Jahn SMS 1
    was a 3 hour design Maximum operating depth 200 meters Here you find nice pictures of Jan Jahn s SMS 1 This particular unit was mainly used in sweet water courtesy Dräger Scrubber with 1 2 fill adapter This unit was used with supply hose not from a UW cabin as should originally be but from surface in a deep freshwater dam That is why an adaptor was used the supply hose came from surface so it was connected in the upper part of the rebreather I have removed the adapter by drilling off the screws they were covered by a thick layer of epoxy and that is why you can see a red tape inside the frame and white spots I have not painted the plugs yet on its outer side I use the SMS1 recently as a SCR wearing two 2 7 l bottles in stage positions with different mixtures bottom mix and DC mix with regulators on each and with the IP changes a little with depth from both leading into a manifold with exchangeable nozzles I use nozzles from LPG ovens 0 13 0 32 mm diameter In spite of opinions expressed in the rebreather conference
