ABSTRACT:
A non-rise bidet valve comprising a housing having a fluid inlet and first and second discharge openings; a fluid diverting chamber having a fluid admitting opening and first and second outtake ports; a fluid passage connecting the fluid inlet in open fluid communication with the fluid admitting opening of the diverting chamber; a first fluid outlet passage connecting the first outtake port with the first discharge opening; a second fluid outlet passage connecting the second outtake port with a second discharge passage; and a diverter member mounted in the diverting chamber for movement between first and second positions. The diverter member has a stem presenting an exterior portion extending outside of the housing for moving the diverter member between the first and second positions and seals are provided on the diverter member for movement therewith to close the fluid outtake ports to provide for selective diversion of fluid entering said diverting chamber to either the first or second discharge openings during use. The bidet valve also has an integral vacuum breaker valve which is in a vacuum breaker stem chamber that has an air inlet connecting the stem chamber in open communication with atmosphere. The stem chamber has a stem chamber outlet that connects the stem chamber in fluid communication with the diverting chamber. A vacuum breaker poppet valve is mounted in the housing for movement into open or closed closing relation with the air inlet.
