Abstract: A valve having a housing from which projects a stem rotatable about an axis has an actuating assembly with an abutment ring fixed on the housing, formed with an annular slot, and having an abutment projecting radially into the slot. A knob mounted on and rotatable with the stem adjacent the ring carries a single-arm abutment lever pivoted on the knob and having an end engaged in the slot and displaceable radially between a radial outer position angularly engageable with the abutment and a radial inner position so that when the end is in the outer position rotation of the knob is blocked by engagement of the lever end and the abutment. A spring braced between the knob and lever urges the end into the outer position. A radially displaceable button on the knob engageable with the lever is radially inwardly displaceable to move the lever into its inner position.
Abstract: A faucet assembly has a faucet housing having an outlet, a conduit defining a flow path from a supply of water through the housing to the outlet, an openable and closable servovalve in the conduit, and an openable and closable manual valve in the conduit and having a control element movable between a full-flow open position, an intermediate-flow middle position, and a no-flow closed position. A position-detecting switch subassembly mounted on the housing engages the control element and a proximity detector has a detection field adjacent the outlet. A controller connected to the proximity detector, to the switch subassembly, and to the servovalve serves in the closed position of the element for deactivating the detector and closing the servovalve. In the middle position of the element the controller opens the servovalve on detection of an object in the field of the proximity detector. In the open position of the element the controller disables the detector and opens the servovalve.

Abstract: A faucet has a base formed with a outwardly open cavity and a pair of confronting open outlet ports opening into the cavity. A sleeve fitted over the base at the cavity has an inner surface directed radially inward at the base, and is rotatable on the base. A spout extending radially outward from the sleeve is formed with a pair of passages each radially inward at the sleeve inner surface into the cavity. A connector in the cavity is formed with an outer surface radially confronting the sleeve inner surface, with a pair of axially oppositely directed tubular inlet nipples fitted in the outlet ports, and with respective passages extending from the nipples and opening radially outward at the outer surface level with the passages. Seals between the surfaces couple the connector to the spout fitting for joint rotation therewith and preventing fluid flow between the grooves.
