초록

The invention relates to a solenoid valve, particularly for controlling the brake pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle. In known solenoid valves, there is a first hydraulically effective connection of an armature chamber of the solenoid valve to an outlet through the guide of a tappet in a valve insert. The first hydraulically effective connection ends in the form of a blind hole and thus does not permit flushing out gas bubbles which possibly have accumulated in the armature chamber. In order to solv...

청구항

1. A solenoid valve, comprising: at least one inlet and at least one outlet;a valve insert having a central bore;a tappet that is configured to move axially within the central bore of the valve insert, the tappet including a guide region within the central bore that guides the axial movement of the tappet;a valve element with a control cross-section, which is adjusted by axial movement of the tappet;a capsule that is anchored to the valve insert and which defines an armature chamber;an armature that is accommodated in the armature chamber and which is co...
