Abstract
A solenoid valve for metering a fluid into an intake tract (1) of an engine, said solenoid valve comprising a solenoid assembly (2), an armature (3) interacting with the solenoid assembly (2) and a stroke-movable valve disc (4) connected to the armature (3) for opening and closing at least one through-flow aperture (6) formed in a valve plate (5).

A solenoid valve for metering a fluid into an intake tract (1) of an engine, said solenoid valve comprising a solenoid assembly (2), an armature (3) interacting with the solenoid assembly (2) and a stroke-movable valve disc (4) connected to the armature (3) for opening and closing at least one through-flow aperture (6) formed in a valve plate (5), characterized in that the through-flow aperture (6) opens into a recess (7) of an end face (8) of the valve plate (5), which end face is oriented towards the valve disc (4), and in that a sealing face (9) of the valve disc (4) for sealing off the recess (7) from a valve chamber (10) lies opposite the recess (7), wherein the armature (3) and the valve disc (4) are substantially pressure compensated in a closed position, and further wherein the armature (3) and the valve disc (4) have faces (12, 13) which lie opposite one another at the valve chamber (10) and are substantially equal in size in order to achieve a pressure balance in the closed position.
