Abstract: A floatless water inlet valve for use in toilet tank comprising an inlet pipe, a valve body, a valve arrangement, a valve control device and a central pipe. The valve body includes a dual sleeve tubular member, the lock means end of which is capable of vertically adjustably engaging with the inlet pipe by the inner circumference of the outer pipe of the tubular member. The upper section above the flange of the inlet pipe forms into an annular retaining part composed of spacings mostly in definite arrangement thereby permitting adjustment of the valve in height in relation to the height of the water tank and regulation of the water level in the tank. The valve arrangement disposed on the top end of the tubular member includes a block the interior of which forms a valve house and a release valve, a rubber valve placed beneath the block and being closable and openable in respect of the opening at the upper end of inner sleeve pipe.

Abstract: A floatless outlet valve comprises a valve body having a vertically disposed overflow tube and a valve seat formed integrally at the lower end of the tube. A valve assembly is pivotably connected to the terminal end of the overflow tube by the rear end portion of arm extensions thereby allowing valve of the disc to be closable and operable with respect to the valve port. A cup-like control member with a valve rod is capable of discharging water in the tank completely or partially in accordance with the user's need.
