PROBLEM TO BE SOLVED: To provide a check valve for a solenoid valve, which comprises a check valve seat arranged at an edge of a fluid channel and a movable closure element for carrying out a directional throughflow function and a sealing function.SOLUTION: A closure element 22 has a sealing cone 24, an abutment leg part 28, and an elastic packing ring 26 arranged between the abutment leg part 28 and the sealing cone 24. The abutment leg part 28 forms, in the case of sealing, a placement face 28.1 for the elastic packing ring 26. The present invention also relates to a solenoid valve provided with such a check valve. A first support face 18.1 is formed at the edge of a check valve seat 21, and the first support face, in the case of sealing, forms a mechanical axial stopper 18 for the movable closure element 22, together with a second support face 28.2 that is formed at the outer edge of the abutment leg part 28 in the direction of the check valve seat 21.SELECTED DRAWING: Figure 2
【課題】本発明は、流体通路のエッジに配置される逆止弁弁座と、指向性の貫流機能および密封機能を実施するための可動な閉鎖要素とを備える、ソレノイド弁のための逆止弁を提供する。【解決手段】閉鎖要素22は、密封円錐体24と、当接足部28と、該当接足部28と密封円錐体24との間に配置される弾性パッキンリング26とを有している。当接足部28は、密封の場合に、弾性パッキンリング26のための載置面28.1を形成する。また本発明はこのような逆止弁を備えたソレノイド弁にも関する。逆止弁弁座21のエッジに第1の支持面18.1が形成され、第1の支持面は、密封の場合に、前記逆止弁弁座21の方向において前記当接足部28の外側エッジに形成された第2の支持面28.2とともに、前記可動な閉鎖要素22のための機械的軸線方向ストッパー18を形成する。【選択図】図2
