Beschreibung
Zusammenfassung:	The magneto-pneumatic timing device is operable from a source of differential pressure provided by a first pressure source and a second pressure source at a higher pressure than the first to provide an output pressure signal to an end use device alternating between high and a low output pressures at a predetermined duty cycle. A housing has a chamber having a flexible diaphragm separating the chambers into two subchambers, the device having an inlet communicating with the first subchamber. A conduit connects the inlet to the first pressure source, the conduit having an outlet intermediate the inlet and first pressure source for connection to the end use device. The flexible diaphragm has a first position where the high output pressure is provided at the outlet and a second position where the low output pressure is provided at the outlet. The diaphragm is susceptible to magnetic forces, magnetic force biasing the diaphragm to the first position. The differential pressure between the first and said second subchambers is controlled to move the flexible diaphragm between the first and second positions.
