Abstract
A regulator includes a box-like body containing a device for regulating the flow of air. A tube connected to the box-like body carries a mouthpiece. An air inlet hose is connected to the box-like body by means of an inlet valve. This valve is controlled by the regulating device. One or more exhaust hoses are connected to the box-like body. A tube formed integrally within the box-like body of the regulator bypasses the chamber of the regulating device.
Claims5
A regulator comprising:
- a body having a first end and a second end;
- a chamber in said body, said chamber containing a regulating device for regulating flow of air;
- a mouthpiece tube connected to the first end of the body and carrying a mouthpiece, said mouthpiece being positioned on the tube;
- an air inlet hose connected to the body by means of an inlet valve, the valve being controlled by the regulating device;
- a diaphragm for actuating the regulating device when a user inhales;
- at least one exhaust hose connected to the body;
- and
- a bypass tube which bypasses the chamber of the body, the bypass tube being formed integrally within the body of the regulator, said bypass tube being contiguous such that all air entering said inlet hose flows directly into said mouthpiece tube bypassing an interior of the chamber, thereby creating a pressure drop in the chamber allowing less pressure on the diaphragm making it easier for the user to breathe.
