摘要： A water powered waste disposal apparatus (10) has an adjustable valve (14) with adjustable operating pressure requirements. The disposal apparatus (10) has a plurality of cutters (34) disposed in a passageway (30) for cutting waste. A reciprocating piston (74) is driven by pressurized water in an annular chamber (58). The piston (74) is coupled to at least one rotatable cutter (54). The valve (14) has a reciprocating control piston (110) for selectively diverting the pressurized water into the annular chamber (58) on alternate sides of the drive piston (74). A reciprocating pilot piston (160) selectively conveys the pressurized water to alternate sides of the control piston (110) in response to water pressure in the annular chamber (58). A detent (208) and spring (218) apply an amount of resistance to the pilot piston (160) such that water pressure in the annular chamber (58) must reach a certain threshold pressure to overcome the resistance of the detent (208) and spring (218). An adjustment mechanism (230) has a threaded member (234) engaging the spring (218) to adjust the amount of resistance applied by the detent (208) to the pilot piston (160) as the threaded member is advanced and retracted.

摘要： A waste disposal apparatus (10) has a cutter apparatus (14) with angled teeth. The cutters (34) may be disposed in a passage of a housing having an inlet and an outlet. The cutter apparatus has a stationary cutter (42) and a pivoting cutter (43) which pivots with respect to the stationary cutter. The stationary cutter has a plurality of teeth intermeshing with a plurality of teeth on the secondary cutter as the secondary cutter pivots. The teeth of the stationary and pivoting cutters have edges that extend towards one another at an angle with respect to a traverse direction perpendicular to a longitudinal axis such that the teeth meet at an angle. Each edge has a leading edge which meets first to concentrate cutting force at a point along the edge. The force moves along the edge from the leading edge to a trailing edge. A drive means rotates the pivoting cutter. The waste disposal apparatus may be a water powered waste disposal apparatus. The drive means may have a housing defining an annular chamber with a drive piston slidingly disposed therein and coupled to the pivoting cutter.
