Abstract
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.
