Estimating the term…
A compressor provided with a torque limiter constructed such that, in view of possible occurrence of accidental locking of the compressor, in the case where a one-way clutch is used in place of an electromagnetic clutch in order to permit a refrigerant compressor for a vehicle air-conditioning system to be driven by an electric motor instead of an internal combustion engine, when an excessive torque is to be transmitted by the one-way clutch, rollers ride over wedge surfaces and fall into pocket sections, or sprags are reversed to roll-over.
A compressor provided with a torque limiter, the compressor being additionally provided with a power transmission mechanism and rotationally driven by an external rotational power source via said power transmission mechanism, characterized in that said power transmission mechanism comprises a one-way clutch section and, while the torque load acting upon said compressor is within the range of normal value, said one-way clutch section is in engagement so as to transmit the rotational power from said rotational power source to said compressor whereas, when the torque load acting upon said compressor increases unusually above a predetermined value, said one-way clutch section becomes disengaged so that the transmission of the rotational power from said rotational power source to said compressor is shut off, and the rotational power is not transmitted again once the transmission of the rotational power is shut off.
