<p>A swash plate type compressor with a variable displacement mechanism is disclosed . The compressor includes a compressor housing (10) having a cylinder block (11) provided with a plurality of cylinders (25) and a crank chamber (20b). A piston (26) is slidably fitted with each of the cylinders (25) and is reciprocated by drive mechanism. The drive mechanism includes a drive shaft (24) rotatably supported by the compressor housing (10). Rotor plate (30) fixed on drive shaft (24) and a swash plate (27) having a surface with an adjustable incline angle. The incline angle varied in accordance with the pressure in the crank chamber (20b). A wobble plate is disposed adjacent the swash plate (27) to convert the rotating motion of the drive shaft (24), the rotor (24-30) and the swash plate (27) into the reciprocating motion of the pistons (26) which are coupled to the swash plate (27) through corresponding connecting rods. A hinged joint mechanism hingedly connects an arm portion (27c-27d) of the swash plate (27) to an arm portion (29a-30a) of the rotor plate (29-30) to permit variations in the incline angle of the swash plate (27). The compressor includes two hinge joint mechanism which are slidably projected two arm portions (27c-27d) extending from the swash plate (27) and two rotor plates (29-30) connecting the drive shafts (24) to be securely supported against the large moment of the reaction compression from the piston (26). <IMAGE></p> |
