Abstract: A removable and replaceable dispensing head for a fluid dispenser system adapted to deliver the fluid to a user includes a hollow shank extending on an axis. A shank hub is attached to the hollow shank, and an aperture aligned with the hollow portion of the shank extends through the shank hub. A first fixed body is removably attached to the shank hub, the first fixed body and shank hub each having corresponding first attachment means arrayed in a predetermined pattern. A fluid conveyance path is provided through the hollow shank, first fixed body and shank hub. A second fixed body is provided having a second attachment means arrayed in the same predetermined pattern, the second attachment means corresponding to the first attachment means in the shank hub enabling removable attachment of the second fixed body to the shank hub upon removal of the first fixed body from the shank hub.

Abstract: A poppet valve assembly wherein the valve stem is protected from water contact. The valve includes a housing, a valve stem reciprocable within the housing, and a valve seal over the stem. The seal is a boot or sleeve having a base end and a valve end. The base end is open and sealed about its entire periphery to the housing. The valve end seals against the end of the valve stem. The housing defines a valve seat, and the valve end of the seal includes a valve portion selectively engaging the seat. Preferably, the seal further includes a bellows portion along its length to bias the valve portion into engagement with the valve seat.
