ABSTRACT:
A pressure control system for use in vehicle emissions control includes an air control valve (12) having a housing (14) defining an inlet (16) communicated to the vehicle air pump and a pair of outlets (18, 20). A primary valve assembly (22) controls communication between the inlet (16) and the outlets (18, 20) and includes a pair of valve members (54, 56) actuated by a differential pressure responsive diaphragm assembly (39). The pressure differential across the diaphragm assembly (39) is controlled by a pressure signal generated from a pressure tap (84) from the inlet (16). A pair of solenoid valves (88, 92) controls communication to the diaphragm assembly and to a pressure responsive relief valve assembly (60) which controls communication between the inlet (16) and an atmospheric vent (78).
