Embodiment Construction

[0020] as by figure 1 It can be seen that the illustrated embodiment of a spool 1 for a normally open solenoid valve comprises a sleeve 3, a valve insert 7, an armature 4 with a push rod 5 having a closing body 5.1 and a main sealing element 5.2 and a return Spring 6. A solenoid assembly (not shown in detail) generates an electromagnetic force that moves the longitudinally displaceable armature 4 with the plunger 5 against the force of the return spring 6 toward the valve insert 7 . Furthermore, the valve insert 7 accommodates a valve body 8 which includes a main valve seat 8.1 into which the main sealing element 5.2 engages in a sealing manner for the sealing function of the solenoid valve. as by figure 1 It can further be seen that the shown valve core 1 includes a check valve 20 for realizing the directional flow function according to the present invention.

[0021] as by figure 1 It can further be seen that the valve slide 1 is locked with the receiving opening in the ...

Abstract

The invention relates to a check valve (20) for a solenoid valve and a solenoid valve with such a check valve, the check valve having a check valve seat (21) arranged at the edge of a fluid channel (14) and a movable closing element (22) for directional flow and sealing function, wherein the closing element (22) has a sealing cone (24), an abutment base (28) and is arranged between the abutment base (28) and the sealing cone The elastic sealing ring (26) between (24), wherein the abutment seat (28) forms the bearing surface (28.1) for the elastic sealing ring (26) in a sealed condition. A first support surface (18.1) is formed at the edge of the non-return valve seat (21), which is sealed against the outer edge of the seat (28) towards the non-return valve seat (21). The directionally configured second support surface (28.2) forms a mechanical axial stop (18) for the movable closing element (22).

Description

technical field [0001] The invention relates to a check valve for a solenoid valve of the type according to independent claim 1 . The object of the invention is also a solenoid valve with such a non-return valve. Background technique [0002] Solenoid valves are known from the prior art with a magnetic assembly, a spool and a valve lower part, wherein a first fluid channel and a second fluid channel are formed between the fluid inlet and the fluid outlet, the flow cross section of the first fluid channel can be determined by The main valve regulates, and the flow cross-section of the second fluid channel can be adjusted by a directional check valve. Such a solenoid valve can be used, for example, in an anti-lock brake system (ABS) or an actuation slip control system (ASR system) or an electronic stability program system (ESP system). [0003] A solenoid valve with a magnetic assembly, a valve slide and a valve lower part is known from DE 10 2007 042 717 A1. The spool cons...
