摘要： A variable displacement type compressor circulates a refrigerant in an air conditioning circuit. The compressor has a compression mechanism and a displacement controller. The compression mechanism compresses and discharges the refrigerant. The displacement controller controls the discharge amount of the refrigerant of the compressor. The displacement controller further includes a normal control means and a protective control means. The normal control means controls the displacement based on a cooling load. The protective control means controls the displacement based on the value in connection with the rotational speed of the compressor and the actual operating information of the compressor.

摘要： A piston includes an engagement portion that engages with a swash plate. The engagement portion is provided with a pair of arm portions and a coupling portion for coupling base ends of the arm portions each other. An axial rib extending in the axial direction is integrally provided in a central part of a back surface of the coupling portion in the width direction orthogonal to a central axis of a head portion of the piston. An accommodation groove is formed on an inner circumferential surface of a cylinder bore corresponding to the axial rib, such that the axial rib does not interfere with the cylinder bore when the piston moves to the top dead center.
