Abstract:
A valve for metering fluid under pressure includes: a valve housing which has an inlet opening and a metering opening as well as a valve seat enclosing the metering opening having an outwardly pointing seat surface; a valve needle carrying a closing head; a valve-closing spring acting on the valve needle and applying the closing head to the valve seat; and an electrical actuator, which applies a compressive force to the valve needle, lifting the closing head outwardly away from the valve seat. To prevent transverse forces on the valve needle, which can cause a deflection of the valve needle, a gimbal-mounted spring disk, which is pushed onto the valve needle, is used as the valve-closing spring.
