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 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 mounting bracket for a hand shower having a support stem has a support adapted to be stationarily fixed, a holder formed with a forked seat shaped to receive the hand-shower stem, and interengaging formations on the holder and support for pivoting of the holder on the support about a normally horizontal axis while retaining the holder and support against relative axial movement. An array of radially extending ridges formed on the support, surrounding the axis, and projecting toward the holder engage with complementary ridges formed on a flange of a retaining element rotationally coupled to the holder. A locking bolt axially fixed in the support axially presses the retaining-element ridges against the support ridges so that the holder can be pivoted about the axis on the support with elastic deformation of the flange.

Abstract: A releasable fast-action coupling has a female part formed centered on an axis with an axially outwardly open bore having a smooth-walled inner portion of predetermined diameter and an outer portion of somewhat greater diameter and formed with an internal screwthread. A male tube part having an end engageable in the bore has an inner portion engageable in the inner bore portion and formed with a radially outwardly open groove, an outer portion engageable in the outer bore portion when the inner tube portion is in the inner bore portion and formed with a radially outwardly open groove, and a radially outwardly projecting ridge axially inwardly engaging the bore shoulder when the tube part is fitted in the bore. An elastic seal ring seated in the groove of the tube inner portion radially outwardly engages the bore inner portion when the tube part is fitted in the bore.
