SWASH PLATE COMPRESSOR

WIPO Patent Application WO/2021/241911

A1

The present invention relates to a swash plate compressor comprising: a housing; a rotary shaft rotatably mounted in the housing; a swash plate which is accommodated in a crank chamber of the housing and which rotates together with the rotary shaft; a piston which forms a compression chamber together with the housing, and which is linked to and reciprocates with the swash plate; a discharge path for guiding a refrigerant of the crank chamber to a suction chamber of the housing so that the incline angle of the swash plate is controlled; and a discharge path control valve having a valve chamber provided in the discharge path, and a valve core reciprocating inside the valve chamber, wherein the valve core includes a first communicating path for always allowing communication with the discharge path, and a second communicating path for allowing communication with the discharge path if the differential pressure between the pressure of the crank chamber and the pressure of the suction chamber is included in a predetermined pressure range, and thus the present invention can simultaneously achieve the rapid control of a refrigerant discharge amount and the prevention of degradation in compressor efficiency, and can improve initial driving responsiveness.
