摘要： A scroll type fluid compressor including a housing, a pair of scroll elements each comprising an end plate and a spiral wrap means projecting from one surface of the end plate. Both wrap means are interfitted to make a plurality of line contacts and are formed with a groove on the end surface of each wrap means which receives a seal element. Each groove is formed with its center line inward of the center line of its respective spiral wrap. This construction prevents the walls of the groove from prematurely deteriorating and causing attendant destruction of the scroll elements.

摘要： A reciprocating piston type refrigerant compressor includes a compressor housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is reciprocated by a wobble plate driven by a cam rotor mounted on a drive shaft. The cam rotor includes an adjustable slant plate with a sloping surface at an adjustable slant angle in close proximity to the wobble plate. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the slant angle of the sloping surface. The slant angle of the sloping surface is adjusted in response to the change of pressure in the crank chamber. The crank chamber communicates with the suction chamber through a passageway and a valve control mechanism controls the opening and closing of the passageway. Thus, the capacity of the compressor of the present invention can be adjusted by changing the slant angle of the sloping surface of the slant plate in response to operation of the valve control mechanism.

摘要： A rotation detecting device for a wobble plate type compressor comprises a rear thrust race (23) disposed on the rear surface of the wobble plate (8) and moveable therewith. The rear thrust race has two nail portions (231, 232) and a projecting portion (233). A magnetic pickup (24) is mounted on the cylindrical housing (2) of the compressor and is positioned thereon opposite a locus of movement of projecting portion (233). Magnetic flux leaking from an electromagnetic clutch mounted on the compressor flows to rear thrust race (23) through a drive shaft (17) and bevel gear (14). When projecting portion (233) passes opposite magnetic pickup (24), a magnetic flux is produced. Magnetic pickup (24) detects the magnetic flux and thus detects movement of wobble plate (8). Thus the connection between the compressor and the driving source can be quickly interrupted in the event of compressor malfunction.

摘要： A rotation detecting device for a wobble plate type compressor comprises a front thrust race disposed on a flat end surface of a cam rotor and moveable therein. The front thrust race has two nail portions. A magnetic pickup is mounted on the cylindrical housing of the compressor and is positioned thereon opposite a portion of the locus of movement of the nail portions. When a nail portion passes opposite the magnetic pickup, a magnetic flux is produced. The magnetic pickup detects the magnetic flux and thus detects movement of wobble plate. Thus, the connection between the compressor and the driving source can be quickly interrupted in the event of compressor malfunction.
