Water driven waste disposal apparatus |
摘要 |
A water powered waste disposal apparatus has an adjustable valve with adjustable operating pressure requirements. 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. 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. 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 has a threaded member engaging the spring to adjust the amount of resistance applied by the detent to the pilot piston as the threaded member is advanced and retracted.
