ABSTRACT:
A flush pump is disclosed for use in pumping water from a storage tank to a toilet bowl for flushing waste from the toilet such as in a recreational vehicle. The pump disclosed includes a housing with a bellows disposed therein with an inlet extending into the flush water storage tank and a discharge connected to the toilet bowl. A piston positioned above the bellows is used to depress the bellows upon rotation of the piston by an actuator above the piston. The actuator includes a cylindrical wall portion extending into the housing having a plurality of vertical flanges extending from the cylindrical side wall engaged with the piston side wall such that when the actuator is rotated the piston will rotate therewith. The housing side wall includes a fixed cam which is engaged with an incline flange cam follower extending from the piston side wall such that the piston will move downward upon rotation of the actuator. Each end of the inclinded flange includes a stop to limit the rotation of the piston and actuator. Upon release of the actuator, the compressive forces within the bellows will raise the piston to its original position.
