Abstract: A pneumatic solenoid valve, comprising an electromagnetic actuator and an air chamber with multiple air connections configured to be connected with the interposition of the air chamber via multiple switching positions of the magnetic actuator is disclosed. The actuator is configured to assume three different switching positions by energizing the actuator in a unipolar manner with three different current intensities and to move first and second sealing element via an actuation mechanism when switching between the switching positions. In a first position, a first sealing element closes a first air connection, and a second sealing element releases a second air connection. In a second switching position, the first sealing element closes the first air connection, and the second sealing element closes the second air connection. In a third switching position, the first sealing element releases the first air connection, and the second sealing element closes the second air connection.

Abstract: 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.

Abstract: 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.

In a second switching position, the first sealing element (26) closes the first air connection (3), and the second sealing element (27) closes the second air connection (4). In a third switching position, the first sealing element (26) releases the first air connection (3), and the second sealing element (27) closes the second air connection (4).
