Multi-cycle control valve assembly
Abstract
Abstract A TWO-CYCLE CONTROL VALVE ASSEMBLY FOR COMPRESSED AIR COMPRISES A PLUNGER WHICH CAN BE MOVED AXIALLY WITH REFERENCE TO THE VALVE BODY TO THEREBY OPEN A FIRST INLET VALVE WHICH ADMITS COMPRESSED AIR TO A FIRST CONSUMER. THE RESULTING PRESSURE BUILDUP IN THE BODY CAUSES A COMPOSITE DIAPHRAGM AND A REDUCING ELEMENT BETWEEN THE COMPONENTS OF THE DIAPHRAGM TO EFFECT THE OPENING OF A SECOND INLET WHICH ADMITS COMPRESSED AIR TO A SECOND CONSUMER. IF THE PRESSURE BUILDUP FAILS TO MATERIALIZE AN MECHANICAL OPENING OF THE FIRST INLET VALVE, THE REDUCING ELEMENT EFFECTS MECHANICAL OPENING OF THE SECOND INLET VALVE. THE RESISTANCE WHICH AN OPERATOR MEETS TO DIS- PLACEMENT OF THE PLUNGER IS THE SAME REGARDLESS OF WHETHER BOTH CYCLES ARE OPERATIVE OR WHETHER THE ONE OR THE OTHER CYCLE IS OUT OF COMMISSION.
