Refrigerant compressor with cooling fan

摘要

A refrigerant compressor with a drive power transmission unit accommodating therein a cooling unit capable of promoting heat dissipation from the drive power transmission unit including a rotor element operatively linked to a vehicle engine, a rotary hub-like plate fixed to a drive shaft of the compressor, the rotor element and the rotary hub-like plate being separate members and operatively connected through a transmission controlling member formed by a damper member and a torque limiter. The damper member and the torque limiter are deformable to perform their transmission controlling function. Fins may be formed in a radial arrangement around the axis "L" of the drive shaft on the rotary hub-like plate.
