Abstract (en)
[origin: EP0962655A2] The present invention relates to a piston-type compressor comprising a casing having a plurality of bores, a plurality of pistons respectively inserted into each bore, a driving means for sequentially moving said pistons to suck and to discharge a gas into and from the bores, an sucking valve mechanism including a valve seat plate and an sucking valves, and a discharging valve mechanism. In such compressor, whole of an abutted area on the valve seat plate or the whole of the abutting area on each sucking valve to be abutted to the valve seat plate is roughed. Thus, separation of the sucking valve from the valve seat plate in sucking the gas into the bores is facilitated. <IMAGE>
