Abstract:
1. An over-torque protector device for a compressor having a drive shaft, said device having engaged and released states and comprising: a drive pulley defining a substantially central opening about a central axis and a face, said drive pulley comprising a plurality of receptacles extending from said face; and a drive hub comprising: wherein relative rotation between said drive pulley and said drive hub about said central axis is imparted by driven rotation of said drive pulley and arrested rotation of said drive hub, said coupling means and said receptacles having relative axial movements in directions substantially parallel with said central axis induced by said imparted relative rotation between said drive pulley and said drive hub, the transition from said device engaged state to said device released state induced by said relative axial movements of said coupling means and said receptacles, whereby said drive pulley is continually rotatable about said central axis relative to and unencumbered by said drive hub in said device released state.
