Abstract:
1. A swash plate type variable displacement compressor comprising: a rotary shaft; a swash plate rotated by driving force of the rotary shaft, the swash plate being inclinable at a variable inclination angle; a plurality of pistons engaged with the swash plate, the pistons being reciprocable in accordance with the rotation of the swash plate so that a length of stroke of each piston is varied depending on the inclination angle of the swash plate; a first rotor connected to the rotary shaft for rotation therewith; a second rotor transmitting the rotation of the first rotor to the swash plate; a solenoid producing electromagnetic force that acts on the first rotor or the second rotor so that the first rotor and the second rotor move toward each other; and a cone clutch engageable by energization of the solenoid, the cone clutch having a male cone portion and a female cone portion, the male cone portion having a conical surface provided on one of the first rotor and the second rotor, the female cone portion having a conical surface provided on the other of the first rotor and the second rotor, the conical surface of the female cone portion being connectable to and disconnectable from the conical surface of the male cone portion.
