Abstract
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.
