A rotation sensor for sensing a swash-plate type compressor being in rotational state. An electromagnetic sensor including a permanent magnet and a coil disposed in the neighborhood thereof is fixed on a housing of the compressor such that it may be opposed to a part of a rotational locus described by a specific portion of the external periphery of the swash-plate. The electromagnetic sensor generates a signal pulse everytime the specific portion passes nearby. When the swash-plate is made of a non-magnetic material some magnetic body is fixed on the external periphery of the swash-plate for constituting a portion-to-be-sensed. This magnetic body may be a ring or lump of ferrous material, a temperature sensitive ferrite, a permanent magnet, etc.
A rotation sensor for a swash-plate type compressor which includes a housing with at least one cylinder bore, a rotary shaft rotatably retained by said housing, a swash-plate secured thereto in a slant posture, and at least one piston engaged with said swash-plate for being reciprocated in said cylinder bore according to the rotation of said swash-plate, said rotation sensor comprising:
