<p>Cam actuated valves for compressors include mechanisms for changing an instant when the cam actuated valve is opened and/or a time interval during which the cam actuated valve is in an open state within the time range of a compression cycle. A reciprocating compressor has: a body (910) including a compression chamber (922); a cam having an oblong portion, being located inside the body and being configured to be rotated around a rotation axis, to perform a rotation during each compression cycle;an actuating element located inside the body and configured to receive a linear displacement or an angular displacement due to the oblong portion of the cam;and a valve (932) located on a flow path of the fluid toward or from the compression chamber (922) and configured to be switched to an open state by the actuating element. The reciprocating compressor also includes a controller configured to adjust timing of the valve.</p> |
