FIELD: machine engineering.
SUBSTANCE: piston compressor 300 includes a compression chamber 310 for compressing fluid introduced through a suction opening into the compression chamber and discharged from said chamber after compression through a discharge opening. The actuator 350 is configured to generate angular movement. The rotary valve 340 is adapted to receive said angular movement and regulate opening and closing of the suction and discharge openings depending on the angular movement. The rotary valve 340 comprises a rotary disc made rotatable due to angular movement. There is a first opening providing input of the input fluid flow into a compression chamber when the first opening is aligned with the suction opening and a second opening providing outlet of the outlet fluid flow from the compression chamber when the second opening is aligned with the outlet opening. It is possible to adjust both the suction and discharge flow channels with a single actuator.
EFFECT: improvement of the rotary valve.
