ABSTRACT:
A water powered waste disposal apparatus has an improved valve with floating seals and water passages. The disposal apparatus has a plurality of cutters disposed in a passageway for cutting waste. A reciprocating piston is driven by pressurized water in an annular chamber. The piston is coupled to at least one rotatable cutter. The valve has a reciprocating control piston for selectively diverting the pressurized water into the annular chamber on alternate sides of the drive piston. The floating seals have slots formed therethrough for allowing the seals to expand and prevent water from leaking past the control piston and preserving pressure. A reciprocating pilot piston selectively conveys the pressurized water to alternate sides of the control piston in response to water pressure in the annular chamber. Water passages are formed at the ends of the control piston to allow the water to act on the control piston. A detent and spring apply an amount of resistance to the pilot piston such that water pressure in the annular chamber must reach a certain threshold pressure to overcome the resistance of the detent and spring. An adjustment mechanism adjusts the amount of resistance applied by the detent to the pilot piston.
