Patent DE-4118666-A1 (DE)
Title: Regulating method for breathing gas supply for divers - uses breathing impulse as regulating value, and reference pressure, to open and close supply valve
Inventor: LUTHER GUENTER
IPC: B63C11/24
Filed: 1991-06-07
Abstract: The method regulates the breathing gas supply. It uses a valve located in the gas supply circuit, and a breathing gas chamber. During breathing-in, an underpressure of a preset value is generated and determined. The supply valve is maintained in closed position by a reference pressure, and moved into an open working position, by this underpressure. After completion of the breathing-in process, the supply valve is moved into the closed rest position, due to the normal pressure of a preset value, determined in the breathing chamber. During breathing-out, an overpressure of preset value is detected, and used to move a discharge valve into open position. After breathing-out, the normal pressure in the breathing chamber is used, to move the discharge valve into closed position. ADVANTAGE - Reduced breathing resistance and effort.
