無潤滑式コンプレツサ。[Claims for Utility Model Registration] A suction valve device operates during the suction stroke of a reciprocating piston to introduce external air into the compression chamber in the cylinder block, and the introduced external air is compressed during the piston's compression stroke. Accordingly, in a non-lubricated compressor in which a discharge valve device operates to discharge compressed air, both the suction valve device and the discharge valve device have a valve seat portion formed by a tapered hole communicating with the compression chamber of the cylinder block, and the valve seat a case in which ventilation holes are provided radially in a part thereof; a valve element that opens or closes the ventilation hole by a conical valve part that is movably supported inside the case and that engages and disengages from a valve seat part; The valve includes an elastic packing that covers and adheres to the surface of the valve seat and maintains a seal between the valve seat and the valve seat, and a spring that biases the valve body in the direction that the valve seat seats on the valve seat. The suction negative pressure generated in the compression chamber causes the valve body of the suction valve device to move in the direction of opening the vent against the spring, and during the compression stroke, the valve body of the discharge valve device moves against the spring to open the vent hole. A non-lubricated compressor that moves in the direction of opening pores.
