ABSTRACT:
A drive system for a laundry apparatus including a torque sensing drive mechanism for determining the presence of washing fluid in the cavity of a rotary positive displacement pump by means of the different resistive torque responses of relatively full and empty pump cavities. A clutch mechanism joins two driving pulleys that are belt-connected to two driven pulleys on the transmission and pump units. The presence of washing fluid in the pump cavity effects separation of the driving pulleys and actuates only the pump unit. Absence of washing fluid in the pump cavity causes the driving pulleys to remain coupled and a centrifugal extraction operation is initiated through the transmission and spin clutch.
