Provided is a compressor having an enhanced capability of supplying oil to a thrust bearing and a radial bearing which are interposed between a center through-hole in a cylinder block and a driving shaft. To this end, the compressorhas an air bleed passagewhich is configured to allow crank chamberand intake chamberto communicate with each other, including: a first space Sin the center through-hole; a communicating partfor allowing the first space Sand a second space Sto communicate with each other; the second space Sin the center through-hole; a penetrating passageformed to pass through the driving shaft, thereby allowing the second space Sand a third space Sto communicate with each other; the third space S; and a communicating passagefor allowing the third space Sand an intake chamberto communicate with each other.

Compressor

An air conditioner for a vehicle has a variable capacity compressor for compressing a refrigerant and controlling a discharged volume of the refrigerant by a power source for driving a vehicle, and a controller for setting a second target temperature higher by a predetermined temperature than a preset first target temperate and controlling the discharged volume of the refrigerant based on the second target temperature when entering into a state where fuel consumption of the power source for driving the vehicle is lowered.

Air conditioner for vehicle

A vehicle air conditioning control apparatus having an externally controlled type compressorand an externally controlled type cooling electric fanis disclosed in which a control map, for determining a duty ratio for a fan motorin terms of a compressor discharge pressure Pd, is determined based on the maximum efficiency point, for providing the maximum fuel consumption, that allows a total engine load torque, represented by a total sum of an engine load torque caused by the externally controlled type compressorand an engine load torque caused by a fan motor, to be a minimum torque, and a duty voltage to be applied to the fan motoris controlled using the compressor outlet pressure Pd and the control map which is determined.

Vehicle air conditioning control apparatus

Between a cylinder block and a housing, there is disposed a valve base plate. The valve base plate is formed with mutually isolated first and second intake openings for fluidly communicating each of piston chambers in the cylinder block with an intake chamber defined in the housing. A reed valve element is incorporated with each piston chamber. The reed valve element is arranged to open the first and second intake openings with the aid of a fluid when the piston is moved away from the reed valve element and close the first and second intake openings with the aid of the fluid when the piston is moved toward the reed valve element. Due to provision of the two, viz., first and second intake openings, opening movement of the reed valve element is carried out along with a twisting motion of the same.
