Abstract
A breathing regulator for scuba diving includes a housing having a high pressure gas inlet and a discharge outlet in conjunction with a pressure regulator valve assembly operatively connected to the inlet. The valve assembly includes a valve support, a valve movably coupled to the valve support at a first location for movement between a first high pressure gas inlet closing position and a second high pressure gas inlet opening position and a layer of material disposed adjacent to the first location to insulate the first location.

A breathing regulator for scuba diving, the regulator comprising:
- a housing having a high pressure gas inlet and a discharge outlet;
- a pressure regulator valve assembly operatively connected to the inlet, the assembly including:
- a valve support including a tube having a length;
- a valve movably coupled to the valve support at a first location for movement between a first high pressure gas inlet closing position and a second high pressure gas inlet opening position;
- and
- a layer of material extending along a portion of the length of the tube and disposed adjacent to the first location.
A breathing regulator for scuba diving, the regulator comprising:
- a housing having a high pressure gas inlet and a discharge outlet;
- a pressure regulator valve assembly operatively connected to the inlet, the assembly including:
- a tube of the first material operatively connected to the gas inlet;
- a valve poppet mounted in the tube to control the flow of high pressure gas through the tube;
- a spring mounted in the tube to bias the valve poppet to a closed position;
- a lever pivotally coupled to the tube at a first location 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
- a layer of a second material blanketed at least partially about the tube adjacent the first location to insulate the first location.
