Abstract: A mixer valve is disclosed for mixing hot and cold water, and controlling the outflowing volume by means of a single handle. The invention includes a control device outside the area to which water is admitted in the headpiece of the valve body and a wobble plate in the headpiece to control valve pistons. The wobble plate is carried by an axle bolt arranged on a secant in a bushing rotating around a fixed axis and being adjustable in its oblique position and its rotating setting by means of a lever assembly mounted in the bushing vertical to the rotational axis with an eccentric part engaging the wobble plate. The valve pistons preferably are tear-shaped and are mounted in spring tight suspension with the incoming water in the closing direction and housed and sealed by means of piston rods in the valve body with the piston rods in contact with the wobble plates at their top end-pieces.

Abstract: A pressure compensating device is disclosed for mixing faucets. The device includes a diaphragm against which the medium to be compensated flows in a housing. The diaphragm is fitted with a throttle plate of flexible material on each side. Each throttle plate includes apertures which widen towards the diaphragm to aid in pressure compensation. Each throttle plate is securely fastened at its edges to the diaphragm and the casing and is secured at its center by a pin and spacers to the center of the diaphragm.

Abstract: A shower head is disclosed for regulating water flow. Improvements enable a constant shower spray to be produced even though changes may occur in the pressure in the main lines. According to the invention, this is brought about by arranging outlet holes of the shower head in a flexible diaphragm-like disc held in the shower head casing by its edge. This disc reacts to slight changes in main line pressure to flex and adjust the volume of water within the head, thereby adjusting the resultant pressure within the head to compensate the change to main line pressure. This flexure of the disc also dislodges lime deposits and the like from the outlet holes, thereby providing a self-cleaning function.
