Abstract
A non-return valve for a solenoid valve includes a non-return valve seat and a movable closure element. The valve seat is arranged at an edge of a fluid channel. The movable closure element is configured to carry out a direction-orientated throughflow and sealing function. The closure element includes a sealing cone, an abutment base, and a resilient sealing ring. The sealing ring is arranged between the abutment base and the sealing cone. The abutment base forms, in the event of sealing, a support face for the resilient sealing ring. At an edge of the non-return valve seat there is a first support face which in the event of sealing forms with a second support face which is formed at the outer edge of the abutment base in the direction of the non-return valve seat a mechanical axial stop for the movable closure element.
