Solenoid valve

A solenoid valve, comprising:

• at least one inlet and at least one outlet;
• a valve insert equipped with a tappet that is guided in sliding fashion;
• a valve element with a control cross-section that the tappet is able to control;
• a capsule that is anchored to the valve insert and delimits an armature chamber;
• an armature that is accommodated in moving fashion in the armature chamber and which actuates the tappet;
• a first hydraulically effective connection provided between the armature chamber and the outlet, which is embodied in the valve insert in a guide region of the tappet;
• and
• at least one second hydraulically effective connection of the armature chamber to the outlet is provided, which is embodied remote from the guide region of the tappet,
• wherein the at least one second hydraulically effective connection includes at least one longitudinal groove that is open toward an outside of the capsule and extends in an axial direction of the valve insert, and
• wherein the longitudinal groove has a groove depth that is greater than a groove depth of an annular groove that is embodied on the valve insert and belongs to a pressure-tight crimped connection between the capsule and the valve insert.

A solenoid valve, comprising:

• at least one valve inlet and at least one valve 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 configured to actuate the tappet by moving axially in the armature chamber in response to a magnetic field generated around the armature;
• a first hydraulically effective connection provided between the armature chamber and the at least one valve outlet, the first hydraulically effective connection being embodied in the guide region of the tappet;
• and
• at least one second hydraulically effective connection of the armature chamber to the at least one valve outlet, the second hydraulically effective connection being embodied remote from the guide region of the tappet,
• wherein the first hydraulically effective connection receives fluid from a first fluid inlet and discharges the fluid from a first fluid outlet into the armature chamber, and the at least one second hydraulically effective connection receives the fluid from the armature chamber through a second fluid inlet and discharges the fluid to the at least one valve outlet from a second fluid outlet such that a hydraulic flow path is established from the first fluid inlet to the first fluid outlet through the armature chamber to the second fluid inlet and out of the second fluid outlet.
