Sealing system for a solenoid valve and solenoid valve

摘要

A sealing system for a solenoid valve is provided for accommodation in a recess in an actuating element movable by a coil. The recess proceeds from an end face of the actuating element close to a valve seat. The actuating element is movably mounted in a solenoid valve and designed to clear or close the valve seat (30). A sealing disk and a spring element biasing the sealing disk are provided, wherein the spring element is arranged on the end face facing away from the valve seat centered with respect to the sealing disk and exerts a force on the sealing disk in direction of the valve seat. The sealing disk is axially shiftably guided in the actuating element. A solenoid valve itself includes such sealing system.

1. A sealing system for a solenoid valve for accommodation in a recess in an actuating element movable by a coil, wherein the recess proceeds from an end face of the actuating element close to a valve seat and the actuating element is movably mounted in the solenoid valve and is adapted to clear or close the valve seat, the sealing system comprising a sealing disk and a spring element biasing the sealing disk, the spring element being arranged on an end face of the sealing disk facing away from the valve seat and being centered with respect to the sealing disk and exerting a force on the sealing disk in a direction towards the valve seat, wherein the sealing disk is axially shiftably guided in the actuating element, wherein the sealing system comprises a substantially ring-shaped seal holder which is axially shiftably guided in the actuating element, which accommodates a sealing element in the actuating element's interior and holds the sealing element, wherein the seal holder and the sealing element are a prefabricated unit and together form the sealing disk, wherein the ring-shaped seal holder has at least one radially outer circumferential surface adjacent to an inside of the actuating element serving as a sliding surface, and wherein the seal holder and the sealing element are both completely housed within the recess of the actuating element.
