Abstract:
A swash plate type variable displacement compressor, wherein, when a solenoid (42) of a flow control valve drive mechanism (32) is deenergized, a pilot valve (41) is closed so as to interrupt a working pressure to be introduced into a pressure chamber (35) of a flow control valve (31), thus closing a spool valve (33) so as to interrupt a low pressure side refrigerant path (25) to reduce the amount of refrigerant sucked to a refrigerant suction chamber (7) to zero.
Abstract:
A variable displacement compressor, comprising a delivery pressure area filled with a delivery pressure and a gas feed path for feeding gas from the delivery pressure area to a crank chamber, wherein an inlet side valve mechanism is provided in the gas feed path and opens and closes the gas feed path to control a pressure inside the crank chamber, an adjusting mechanism is provided in the gas feed path between the inlet side valve mechanism and the crank chamber and changes, with the elapse of time, the amount of gas fed from the delivery pressure area to the crank chamber through the gas feed path in response to the opening of the gas feed path by the inlet side valve mechanism, whereby the delivery capacity of the compressor can be changed rapidly to the minimum delivery capacity, and the compressor can be operated at the optimum efficiency.

Abstract:
A housing has a crank chamber (2a) and a cylinder bore (1a). In addition, the housing has a discharge chamber (3b) and an intake chamber (3a) which can communicate with the cylinder bore (1a). A driving shaft (4) is supported on the housing, and a piston (17) is received in the cylinder bore (1a). A swash plate (13) is supported on the driving shaft (4) in such a manner that it can be integrated with the driving shaft and that the inclination angle thereof can be changed, and the piston (17) is reciprocated by virtue of the wavy rotation of the swash plate (13). During the operation with the swash plate (13) in an upright position, a control device (57) switches on an electromagnetic solenoid (39), causes lubricant oil from an oil supply pump (27) to be supplied to a pressure chamber (26) to thereby move a spool (24), whereby the swash plate (13) is temporarily held at an inclined position from the upright one.
