Abstract

PURPOSE: To regulate pressure accurately and also to prevent pumping efficiency by constituting such that a valve disc is operated for feed hole from a compression chamber side in the captioned device for pulsating pump.
CONSTITUTION: A suction chamber 3 having an inlet port 2 and a compression chamber 5 having a discharge port 4 are provided in a cylinder 1. A cylindrical pressure regulating valve 8 arranged rotatably in the suction chamber 3 penetrates a bulkhead 10 partitioning the suction chamber 3 and the compression chamber 5, and an opening on its one end is projected into the compression chamber 5 to connect the suction chamber 3 through to the compression chamber 5. A check valve 6 provided in the compression chamber 5 is elastically in touch with the one end opening of the valve, and a counterflow hole connecting the suction chamber 3 and the compression chamber 5 through the bulkhead 10 is capable of changing the area of an opening facing the compression chamber at a valve disc on one end peripheral edge of the valve positioned on the compresion chamber side.
