Title: Single handle mixer valve

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.
