摘要:
The invention relates to a solenoid valve (1) comprising an armature assembly (5) that displaces an armature (4) in a longitudinally displaceable manner inside a guide sleeve (2) counter to the force of a return spring (6) against a pole core (3). According to the invention, the longitudinally displaceable armature (4) and the pole core (3) respectively comprise at least one stepped section (4.1, 3.1) that engage with each other and which form a plunger-type stepped section (7). The magnet armature stepped section (4.1) and/or the pole core stepped section (3.1) are geometrically aligned such that during operation, an associated edge pair of the magnet armature stepped section (4.1) and the pole core stepped section (3.1) constantly overlap (10, 11) in order to guide the displaceable armature (4) during engagement of the plunger-type stepped section (7).

The invention relates to a magnet assembly (1) for a solenoid valve, having a housing (10), which comprises a housing jacket (12) as the ferromagnetic circuit upper part, a cover disc (14) pressed into the housing jacket (12) as the ferromagnetic circuit lower part, and a coil body (20), which is arranged inside the housing (10) and comprises a winding carrier (21) wound with a coil winding (25), wherein tolerance-compensating means (26) are arranged on the coil body (20). The invention also relates to a corresponding solenoid valve having such a magnet assembly (1). According to the invention, the tolerance-compensating means (26) are configured so that the winding carrier (21) is pressed by means of a lower flange (24) against the pressed-in cover disc (14) in such a way that a boundary surface (24.1) of the lower flange (24) is seated substantially without gaps against a boundary surface (14.1) of the cover disc (14), in order to form a thermal transition resistance that is as low as possible.
