FIELD: reciprocating compressors.
SUBSTANCE: invention can be used in reciprocating compressors. The valve-piston compressor contains at least one piston (1) connected through a connecting rod to the crankshaft with the possibility of its reciprocating movement in the cylinder, as well as inlet and outlet valves. The inlet valve (2) is a poppet and is made with the possibility of forced opening by means of a camshaft cam and closing by means of a spring. The outlet valve is a petal type and is made with the possibility of its opening-closing under the action of a pressure difference. The diameter of the camshaft drive sprocket corresponds to the diameter of the crankshaft drive sprocket, which are interconnected by a chain drive. There is a drive shaft with an oil pump drive sprocket driven by a chain drive.
EFFECT: providing an increase in speed and in synchronizing the operation of the output shaft and the compressor camshaft.
