ABSTRACT:
The invention relates to a toilet flush actuator mechanism for a toilet tank which has a discharge port surrounded by a valve seat having a central axis, a ball-cock type valve, and a flush valve having a vertical axis. The actuator mechanism consists of a trip lever pivotally mounted to the toilet tank and having a free end over which a boot member is telescopically and captively held. First and second resilient guide members extend laterally from the boot member adjacent the free end, and are parallel, coplanar, and separated by a fixed distance. A linkage member is captively carried in fixed relationship with the upper end of the flush valve and has an open void region through which the free end extends. This permits a slidable bearing relationship between the linkage member and the boot member intermediate the first and second resilient guide members as the trip lever pivots upwardly to lift the flush valve thereby retaining the co-axial alignment of the vertical axis of the flush valve and the central axis of the valve seat.
