ABSTRACT:
A flush valve for use with a toilet tank assembly having a flush outlet surrounded by a valve seat, an overflow pipe, and a lift arm movable to initiate flow through the valve seat includes a one piece integral body of molded plastic material. The valve body includes a float fabricated on one end that is aligned with the valve seat to control flow therethrough. An integral beam is fabricated at another end of the body. The float and beam are interconnected by planar portions of the body. A mounting collar is also integrally formed on another planar portion of the body extending from the beam to the collar. The collar may be mounted on the overflow pipe to secure the valve to the toilet tank assembly. An elongated lift strap integrally fabricated with the body extends from the float member and includes a tooth structure for attachment to the lift arm. A reduced thickness integral hinge formed in the portion of the body between the mounting collar and the beam allows the beam to pivot with respect to the collar. Reduced thickness hinges in the portions connecting the float and the beam allow rotation of the float about the beam.
