FIELD: machine engineering.
SUBSTANCE: invention relates to a cam drive valves, used in reciprocating compressors. It contains the mechanisms to change the cam drive valve opening and / or the time interval during which the mentioned valve is in opened state during the compression cycle. The reciprocating compressor includes a housing 910, containing a compression chamber 922. The cam has an elongated part, located within the mentioned housing with ability to rotate about the rotation axis with one revolution during each compression cycle. The actuator is located within the mentioned housing and adapted to sense the linear or angular movement by means of elongate part of the cam. The valve 932 is located on the path of liquid medium flow, passing towards the compression chamber 922 or from the mentioned chamber, and it is adapted to switch to the opened position by means of the actuator. The reciprocating compressor also includes a controller, designed to regulate the operating mode of the mentioned valve.
EFFECT: heavy loads and fast response.
