Abstract
A compressor includes a front housing, a cylinder block, a cylinder head, a torque transmission mechanism, a reciprocating mechanism, and torque determination means. The torque transmission mechanism includes a pulley, a plate-shaped elastic member, a hub, a drive shaft, and a rotor. The torque determination means includes a first marker affixed to the pulley, a second marker affixed to the hub a first sensor affixed to the front housing which generates a first timing signal when the first marker is positioned within substantially the same vertical plane as the first sensor, and a second sensor affixed to the front housing which generates a second timing signal when the second marker is positioned within substantially the same vertical plane as the second sensor. Moreover, there is a time differential between the generation of the first and second timing signals corresponding to the angular offsets, and the torque of the compressor is determinable from the time differential.
