Claims

[Scope of utility model registration request]

A swash plate is tiltably supported on a rotating shaft in a housing that defines a crank chamber, a suction chamber, a discharge chamber, and a cylinder bore that connects these chambers, and accommodates a single-headed piston in the cylinder bore so as to be capable of reciprocating linear movement. , the swash plate is tiltably connected to a rotating support on a rotating shaft, and the rotational movement of the swash plate is converted into the reciprocating linear movement of the single-headed piston through a shoe interposed between both surfaces of the swashplate and the neck of the single-headed piston. In a swash plate compressor, the inclination angle of the swash plate is controlled by the difference between the pressure in the crank chamber and the suction pressure via the single-headed piston. A rotation regulating opposing surface is provided to restrict the range of movement and avoid interference between the single-headed piston and the swash plate, and to absorb the tilting moment that acts on the single-headed piston due to the sliding resistance between it and the swash plate. A piston guide structure in a rocking swash plate compressor in which an opposing surface for receiving a tilting moment is provided between a housing part outside the cylinder bore and the neck of a single-headed piston.
