Abstract:
A water supply coupling for use in a pressurized plumbing system in a recreational vehicle, the recreational vehicle having a wall, the water supply coupling comprising:a tubular body configured to be mounted in the vehicle wall, the body has first and second body ends and a central bore, the central bore having a first bore end for receiving fluids and a second bore end for attaching to and delivering fluids to the pressurized plumbing system,a sealing annulus formed in the central bore between the first and second bore ends,a check member disposed in the bore for movement between an open position away from the sealing annulus wherein water may flow through the body and a closed position seated against the sealing annulus wherein water may not flow through the body, and wherein the check member is formed of a unitary material for forming a seal with the sealing annulus,a spring disposed in the bore between the check member and the second bore end for biasing the check member toward the closed position,a ring member slidably insertable into the bore between the spring and the second bore end wherein the ring member seats against the pressurized plumbing system in use so as to secure the ring member in the bore and resist the biasing force of the spring,the tubular body has external threads at the second body end for attachment to the pressurized plumbing system and an outwardly projecting body flange projecting outwardly from the first body end, anda mounting ring having an inwardly projecting mounting ring flange and a central passage for slidably and rotatably engaging the periphery of the tubular body and limiting movement between the tubular body and mounting ring in response to engagement between the body flange and mounting ring flange.
