A flush valve operating means having a housing with a sleeve assembly therein and a piston actuating means within the sleeve, the housing having two fluid inlets and the sleeve having a by-pass means for diverting fluid from one side of the piston to the other to provide equal fluid pressure over the face of the piston and the piston being slidable within the sleeve in response to fluid supply line pressure being applied to one face of the piston to actuate the flush valve.

In a hydraulic flush valve operating arrangement for use with a fixture having an actuating assembly including: a housing having two fluid inlets; a sleeve assembly in said housing; a piston having a solid face slidable within said sleeve; and fluid by-pass means in said sleeve assembly for diverting hydraulic fluid from one side of said piston to the other; said piston being slidable within said sleeve assembly in response to fluid supply line pressure being supplied to said solid face with substantially equal fluid pressure in each said tubes for actuating said flush valve; and said by-pass means cooperating with said piston and an outlet of said flush valve to a fixture to permit drainage of fluid from said housing into the fixture through said outlet of said flush valve, thereby providing uniform pressure over the face of said piston.
