Abstract
A breathing regulator for scuba diving in cold water, the regulator including a high pressure gas inlet and a discharge outlet, a pressure regulator valve assembly having a brass tube operatively connected to said gas inlet, a valve mounted in the tube to control the flow of high pressure gas through the tube, a lever connected to open the valve poppet, a diaphragm operatively positioned to engage the lever to open the valve poppet, and a plastic tube enclosing the brass tube to prevent icing of the tube.
Claims5
A breathing regulator for scuba diving, said regulator comprising:
- a housing having a high pressure gas inlet and discharge outlet;
- a pressure regulator valve assembly operatively connected to said inlet, said assembly including a brass tube operatively connected to said gas inlet,
- a valve poppet mounted in said tube to control the flow of high pressure gas through said tube,
- a spring mounted in said tube to bias the valve poppet to a closed position,
- a lever connected to open the valve poppet,
- a diaphragm operatively positioned to engage the lever to open the valve poppet on a drop in pressure in the housing and means for insulating the brass tube to prevent icing of the tube.
A breathing regulator for scuba diving, the regulator being of the type having a high pressure gas inlet within a chamber formed within a housing,
- a mouthpiece extending from said housing in fluid communication with said chamber for inhalation of inlet gas and exhalation of exhaust gas, and
- an exhaust valve located in one wall of said housing for directing exhaust gas out of said chamber, the apparatus comprising:
- a metallic tube mounted in said housing,
- a valve poppet mounted in said metallic tube for controlling the admission of high pressure gas into the chamber,
- an exhaust valve in the housing for discharging gas from the chamber, the improvement comprising:
- a plastic tube mounted on said metallic tube to prevent icing of the metallic tube in cold water.
