Abstract: A mixing valve has a valve housing, a thermostatic valve in the housing having a collar extending outward along an axis from the housing, and a stem axially shiftable in the collar. A sleeve surrounds the collar. A retaining part and interengaging screwthread formations between the part and the housing press the part against the sleeve and collar and thereby secure the collar and the sleeve on the housing against axial and angular displacement relative thereto. A handle is rotatably supported on the sleeve and threaded on the stem.

Abstract: A valve stem is provided with a handle assembly having a noncircular axially extending formation and a retaining element fixed to the stem and formed with an array of axially extending and radially deflectable tongues having radially outwardly directed bumps and a screwthread of predetermined axial length axially offset from the stem formation and from the tongues. A handle having a hub formed with a hole fittable axially over the retaining element is formed inside the hole with a screwthread complementary to the retaining-element screwthread, with a handle formation complementary to and fittable axially with the stem formation and offset from the handle screwthread by a distance greater than the retaining-element screwthread axial length, and with a radially inwardly open groove. The handle fits with its hole over the element with the formations interengaged, the screwthreads not engaged, and the bumps in the groove.

Abstract: A mixing valve has a housing and a stem axially displaceable to adjust the output temperature of the valve. A tubular core body fixed in the housing an axially displaceable coupling body having an inner end axially engageable with the stem and an outer end formed with a screwthread. Interengaging formations on the coupling body and the core body inhibit rotation of the coupling body in the core body while permitting axial displacement of the coupling body in the core body. A knob rotatable about the axis has a screwthread meshing with the screwthread of the coupling-body outer end. A retainer engaged between the knob and the core body inhibits axial displacement of the knob on the core body and permits rotation of the knob on the core body so that rotation of the knob on the core body axially shifts the coupling body in the core body.

Abstract: A plumbing fixture has a housing provided with a water inlet and formed with a water outlet and with a circuit pocket. This housing is secured to a support surface. An electrically operated valve in the body between the inlet and outlet has an electrical feed wire energizable for movement of the valve between a closed position blocking flow between the inlet and outlet and an open position permitting such flow. An insert fittable in the pocket is formed with a battery compartment holding a battery. A screw or the like fixed the insert in the pocket. An electrical circuit in the insert connected to the feed wire and to the battery opens the valve on detection of a solid object in front of the housing.

Abstract: A flow-control valve has a valve housing and a valve element in the housing rotatable about an axis through at most 360.degree. between a fully open position for substantially unimpeded fluid flow through the housing and a fully closed position for substantially no fluid flow through the housing and through intermediate positions for intermediate levels of flow through the housing. A spindle coupled to the element extends along and is jointly pivotal with the element about the axis. A handle fixed on the spindle is provided offset from the axis with a handle stop so that the handle stop orbits about the axis as the handle and spindle are rotated to adjust the valve.

Abstract: A bracket for supporting a hand shower adjacent a wall has a base part adapted to be fixed to the wall, formed with a throughgoing passage extending along a horizontal axis generally parallel to the wall, and having axially oppositely directed sides. A holder part pivotal on the base part about the axis on one of the axial sides of the base part is formed on the axis with an upwardly open seat adapted to receive the hand shower. A bolt extending axially through the passage has to the other axial side of the base part a threaded end and to the one axial side of the base part a radially projecting flange bearing axially toward the base part on the holder part. Interengaging formations on the bolt and base part rotationally fix the bolt in the base part while permitting it to move axially therein. A nut threaded on the threaded end of the bolt and bears axially on the other axial side of the base part.

Abstract: A bracket assembly for securing a fitting to a wall. The assembly has a generally T-section plate having a pair of parallel T-flanges, fasteners securing the plate to the wall with the flanges substantially parallel to the wall, a holder adapted to carry the fitting and formed with a T-section slot open at one end, substantially complementary to the flanges of the plate, and normally receiving the plate, and an elastically deflectable latching tongue formed on the holder at the one end and retaining the holder and plate together. Spring formations resiliently engaged between the plate and the holder retain same snugly together. These formations are elastically deformable ribs on the flanges of the plate. The ribs are unitarily formed with the flanges.

Abstract: A thermostatically regulated mixing valve having a housing extending along an axis and a stem in the housing axially displaceable to adjust the thermostatically regulated temperature of the valve has a control assembly with a nut threaded on the housing, axially linked to the valve stem, and rotatable about the axis in one direction to move axially inward and move the stem axially inward and rotatable in the opposite direction to move axially outward and move the stem axially outward. An abutment sleeve is fixed to the valve housing and a sleevelike knob engages over the nut and abutment sleeve and is formed with an inwardly projecting stop. Splines on the knob and on the nut rotationally couple same together but permit relative axial movement so that the knob rotates with the nut but does not move axially therewith.

Abstract: A control assembly used on a thermostatically regulated mixing valve has a housing extending along an axis and a stem in the housing axially displaceable to adjust the thermostatically regulated temperature of the valve. The assembly has a nut threaded on the housing, axially linked to the valve stem, and rotatable about the axis in one direction to move axially inward and move the stem axially inward and rotatable in the opposite direction to move axially outward and move the stem axially outward. An abutment sleeve engageable over the valve housing is formed with a radially outwardly open passage and interengaging formations on the abutment sleeve and valve housing rotationally couple same together. The housing is formed in the sleeve with a radially outwardly open groove level with the passage and a clip engages through the passage with the groove and axially couples the sleeve to the valve housing.

Abstract: A thermostatically regulated mixing valve having a housing and a stem extending along an axis in the housing and axially displaceable to adjust the thermostatically regulated temperature of the valve has a control knob that has a nut threaded on the housing, axially linked to the valve stem, and rotatable about the axis in one direction to move axially inward and move the stem axially inward and in the opposite direction to move axially outward and move the stem axially outward. An inner knob part formed with an angularly extending and axially throughgoing slot is axially coupled to the housing and rotationally coupled to the nut so that the inner knob part rotates with the nut but does not move axially therewith.
