ABSTRACT:
A torque limiting device for a compressor. An input shaft of the compressor is connected to the torque limiting device so that the power source driving the compressor will not be affected if abnormal conditions cause the compressor to generate an excessive load. A flexible connector is located between the power source and the compressor. The flexible connector is deformed when torque is applied to the compressor input shaft. When the applied torque exceeds a predetermined value, a spring is permitted to expand axially, which uncouples the compressor from the power source. The torque at which the device uncouples is stable and predictable.
