Disclosed is a pneumatic solenoid valve comprising an air chamber with multiple air connections which can be connected via multiple switching positions of the valve by interconnecting the air chamber. The valve comprises a magnetic coil, a yoke arranged on the coil, and an armature arranged about the yoke and able to move relative to the yoke, all within the air chamber. When the coil is energized, the magnetic force generated rotates the armature about a single axis of rotation against a restoring force, until the magnetic force corresponds to the restoring force. When the armature rotates, the size of at least one overlapping region between the yoke and the armature changes, wherein an air gap is formed between the yoke and the armature. The distance of the air gap between the yoke and the armature remains substantially constant in the direction of rotation of the armature.

A pneumatic solenoid valve includes a fluid connector, a magnet coil which extends along a coil axis, a yoke arranged on the magnet coil, and an armature movable relative to the yoke and which extends along an armature axis and which is formed for opening and closing the fluid connector. The armature can assume three different switching positions. In the first switching position, the armature and coil axes are arranged parallel to one another and the armature completely closes off the fluid connector. In the second switching position, the armature is rotated about an axis of rotation, such that the armature axis and the coil axis assume an angle with respect to one another and the armature partially opens the fluid connector. In the third switching position, the armature is in a state axially displaced in relation to the first switching position, such that the fluid connector is completely open.

The invention relates to a pneumatic solenoid valve comprising an air chamber (1), on which multiple air connections (2, 3, 5) are provided which can be connected via multiple switching positions of the solenoid valve by interconnecting the air chamber (1). The solenoid valve comprises a magnetic coil (6), a yoke (8) which is arranged on the magnetic coil (6) and made of soft magnetic material, and an armature (9) which can move relative to the yoke (8) and is made of soft magnetic material. The magnetic coil (6), the yoke (8) and the armature (9) are arranged within the air chamber (1). The armature (9) is arranged with respect to the yoke (8) such that, when the magnetic coil (6) is fed with current, said armature rotates about a single axis of rotation (A), by means of the magnetic force generated as a result, against a restoring force until the magnetic force corresponds to the restoring force. When the armature (9) rotates, the size of at least one overlapping region between the yoke (8) and the armature (9) changes, wherein an air gap (L, L) is formed between the yoke (8) and the armature (9) in the at least one overlapping region. The distance formed by the air gap (L, L) between the yoke (8) and the armature (9) remains substantially constant in the direction of rotation of the armature (9).
