Abstract: A dosing valve comprises a valve body having an inlet opening and an outlet opening which extend from a common overflow chamber. This overflow chamber is delimited on one side by the valve body and on the other side by the diaphragm. The diaphragm has a coupling area at the rear, with which it is fastened to an actuating lever. A retaining part clamps the diaphragm between itself and the valve body at the edge. When the valve is opened, the diaphragm is tilted by the actuating lever and then rests on a rotationally asymmetrical supporting surface on the retaining part in the open position.

Abstract: A dosing valve is provided with a valve body having an inlet opening and an outlet opening which extend from a common overflow chamber in the valve body, and a diaphragm which delimits in sections the overflow chamber and is movable between an open and a closed position. In the closed position, the diaphragm rests on at least one valve seat in the overflow chamber and prevents flow from the inlet opening to the outlet opening, wherein the diaphragm is clamped between the valve body and a retaining part and a single-arm actuating lever is provided, which is pivotably mounted on the valve body or the retaining part via a bearing pin and to which the diaphragm is attached and which moves the diaphragm between the positions onto and away from the at least one valve seat.

Abstract: A dosing pump, in particular a microdosing pump, has a pump chamber in which a fluid inlet is provided at a first valve seat and a fluid outlet is provided at a second valve seat. A control element is coupled to an actuator to move the control element in order to vary the pump chamber in terms of volume. The control element is movably mounted by means of a flexure hinge.

Abstract: A valve includes an electrodynamic actuator which has a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable coil which is arranged in the magnetic field and is firmly coupled to a coil carrier. The control element is movable between at least two defined positions. There are provided permanent-magnetically interacting holding force which retain the control element in at least one of the defined positions, even when the coil is currentless.
