ABSTRACT:
A faucet assembly has a housing formed with a vent passage extending between inlet and vent ports and a feed passage extending between an outlet port and a location in the vent passage between the inlet and vent ports. An inner valve body is displaceable in the vent passage between an inner end position sitting in an inner valve seat at the inlet port and blocking flow out of the vent passage through the inlet port and an outer end position sitting in an outer seat and blocking flow from the location toward the vent port. Similarly an outer valve body is displaceable in the vent passage between an outer end position sitting in a vent seat at the vent port and blocking flow out of the vent passage through the vent port and an inner end position permitting flow through the vent port. A mixing valve normally feeds water under pressure to the inlet port and thereby presses the inner valve body into the outer position and, in an abnormal pressure-reversal situation, applies a subatmospheric pressure to the inlet port and thereby moves the inner valve body into the inner position. A faucet arm on the housing carries a removable spray head and a hose has one end connected to the spray head and an opposite end connected to the outlet port of the housing.
