Abstract
A swash plate-type, variable displacement compressor according to the present invention has a structure wherein the shoe holding portion of the piston sandwiches the swash plate from inside. The swash plate is connected to the rotor by a pin which extends in a direction tangential to a surface of a virtual cylinder around an axis of the drive shaft so as to be capable of swinging with respect to the pin. Especially, the position of the pin in the axial direction of the drive shaft is selected, so that a piston top clearance of a piston which is in a top dead center position becomes zero. By this configuration, the piston top clearance of all the pistons may be maintained at zero for all oblique angles of the swash plate. As a result, for any oblique angle, the volumetric efficiency of the compressor may be improved.
