Abstract
An automatic venturi vacuum regulator includes a housing having a pressure inlet port and a vacuum outlet port; a venturi vacuum pump within the housing, the venturi vacuum pump configured to receive compressed air from the pressure inlet port in order to generate suction at the vacuum outlet port; a movable piston configured to seal the pressure inlet port from the venturi vacuum pump responsive to a sufficient pressure differential between the vacuum outlet port and the pressure inlet port; and a check valve configured to seal the vacuum outlet port from the venturi vacuum pump to resist loss of vacuum at the vacuum outlet port.
