機の吸入弁機構。[Claims for Utility Model Registration] (1) A suction valve mechanism disposed in a piston head for opening and closing a suction hole formed in the piston, the outer peripheral surface of which has a moderate frictional resistance against the inner wall surface of the cylinder. A suction valve for a piston-type compressor, which is equipped with a suction valve that slides in a state in which the piston is given a pressure and opens and closes the suction hole by a relative displacement with respect to the piston due to the frictional resistance when the piston reverses motion at the end of its stroke. Valve mechanism. (2) The suction valve is integrated with the piston ring, and opens and closes the suction hole by displacing relative to the piston within a range set between the piston ring and the ring groove when the piston reverses motion. A suction valve mechanism for a piston compressor as claimed in claim 1. (3) The suction valve is made of a plate, the central part of which is fixed to the center of the piston head, and the outer circumferential surface of the suction valve is slidably fitted against the inner wall surface of the cylinder with a predetermined frictional resistance applied thereto. A suction valve mechanism for a piston compressor according to claim 1, which has been registered as a utility model.
