Solenoid valve and method of adjusting of a magnetic drive for a solenoid valve

A solenoid valve for influencing a fluid flow, the solenoid valve comprising:

• a valve housing which defines a working space which is separated by a flexible diaphragm into a fluid region and an actuation region;
• a rocker which is received in the actuation region, the rocker being pivotable between a first functional position and a second functional position;
• a first fluid channel and a second fluid channel extending between an outer surface of the valve housing and the fluid region, a first mouth opening of the first fluid channel being formed as a first valve seat, against which the diaphragm is pressed in a sealing manner in the first functional position of the rocker, the first mouth opening being released by the diaphragm in the second functional position of the rocker;
• and
• a magnetic drive, which comprises a frame-shaped yoke and a solenoid coil arranged in the frame-shaped yoke and a first armature part, which is connected at the end to the frame-shaped yoke and which is accommodated in a coil recess of the solenoid coil, the magnetic drive further comprising a second armature part, which is arranged in series with the first armature part along a coil axis of the solenoid coil and projects beyond the frame-shaped yoke with an end region facing away from the first armature part, the magnetic drive further comprising an intermediate part for a force transmission between the second armature part and the rocker, which is connected with the end region of the second armature part, wherein the end region is frictionally and/or materially connected to the intermediate part, or wherein the intermediate part is positively supported on an annular collar, which extends transversely to the coil axis of a retaining part part, which is non-positively or materially fixed to the end region,
• wherein the magnetic drive rests on a bearing surface of the valve housing with an end face of the frame-shaped yoke penetrated by the end region of the second armature part, and
• wherein the valve housing comprises a valve housing upper part and a valve housing lower part, the diaphragm being arranged in a sealing manner between the valve housing upper part and the valve housing lower part, and wherein a bearing bore which is aligned transversely with respect to the coil longitudinal axis is formed in the valve housing upper part to receive a hinge pin of the rocker, and
• wherein the end face of the frame-shaped yoke, which serves as a reference surface for adjusting the position of the intermediate part, rests on a bearing surface of the valve housing upper part facing away from the valve housing lower part.
