ABSTRACT:
Disclosed is a novel helix drive for use with a valve assembly of a water softener. The helix drive comprises a stationary drive axle bearing a longitudinally slotted sleeve; a piston having an apertured end and being disposed within said drive axle sleeve; a transverse pin, having ends fitted with guide shoes, disposed through said piston aperture and located within said axle slot; and a drive gear having a pair of helix paths within said pin guide shoes are disposed. Rotation of said drive gear results in reciprocating longitudinal movement of the pin within the axle slot and, thus, the piston.
