Abstract (en)

[origin: US4646976A] A magnetic valve, in particular a fuel metering valve for fuel injection systems of internal combustion engines, is proposed which serves to measure the injection quantity and control the instant of injection. In a valve housing, the magnetic valve has an electromagnet and a valve closing element actuated thereby, which cooperates with a fixed valve seat. To damp the opening movement of the valve closing element against a fixed stop and to keep the hydraulic forces of adhesion between the valve closing element and the stop low, a damping chamber that is open toward the valve closing element is disposed on the stop. As the valve closing element approaches, fluid is positively displaced out of the damping chamber in the form of a squish flow between the stop face and the head element of the valve closing element, so that recoiling is avoided due to thus-generated damping. As the valve closing element lifts, fluid can flow through a throttle bore or a check valve into the damping chamber, so that release of the valve closing element from the stop face can be effected with little force being exerted.
