摘要:
A clutch mechanism for use in a rotary power tool having a motor, the clutch mechanism comprising: an input member to which torque from the motor is transferred; an output member that selectively receives torque from the input member; wherein one of the input member or output member is movable between a first position, in which the input member and output member are engaged for co-rotation, and a second position in which the input member and output member are disengaged or disengageable, thereby discontinuing torque transfer from the motor; and an electromagnet which, when energized, moves the moveable one of the input member or output member between the first position and the second position.

The present invention relates to an electromagnetic actuator which reduces power consumption at the time of continuous operation with maintaining controllability. The electromagnetic actuator includes therein a permanent magnet (4) and a switching electromagnet coil (6) which switches a route along which this magnetic flux passes, and is constructed so that, in the case of performing the continuous operation, the magnetic flux of the permanent magnet (4) may pass along a route, which includes an armature (3), by exciting the switching electromagnet coil (6).

A clutch apparatus for a rotary compressor for an air conditioning system is disclosed including a crankshaft (36), an eccentric (42) for engaging an orbiting ring (46) within the compressor, and a plunger (126) disposed within the crankshaft (36). The apparatus further includes a device (136) for axially reciprocating the plunger (126) in the crankshaft (36) so as to cause engagement and disengagement of the plunger (136) into the eccentric (42) whereby the crankshaft (36) transmits torque to the eccentric (142) to rotate the orbiting ring within the compressor.
