ABSTRACT:
An improved dynamic seal for a water powered waste disposer to increase operating efficiency under low water pressure conditions. The rotatable drive ring within the disposer is sealed between the water powered piston chamber and the waste cutting chamber. This seal comprises a thin band of sheet material secured to the drive ring and provides the desired sealing effect due, in part, to the water pressure in the piston chamber.
