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.

Abstract: A check valve for a solenoid valve inclues a check valve seat that is arranged on an edge of a fluid passage and a movable closing element configured to execute a direction-oriented throughflow and sealing function. The closing element includes a sealing cone, a contact foot with a plurality of outflow grooves formed on the edge, and an elastic sealing ring that is arranged between the contact foot and the sealing cone. The outflow grooves form in each case a seating edge for the elastic sealing ring during sealing. The outflow grooves are configured in each case with an arcuate seating edge, which has a predetermined arc length, so that a circle segment of the elastic sealing ring, with an opening angle in the region of 40° to 120°, butts against the respective seating edge during sealing. A solenoid valve includes the check valve.
