Abstract: 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.

Abstract: A fluid bladder valve for a pneumatic vehicle seat adjustment device is disclosed. The valve comprises a first chamber configured to connect to a fluid source, a second chamber configured to connect to the fluid bladder, a third chamber configured to connect to an environment, a fourth chamber connected to the first chamber via a first fluid passage, connected to the second valve chamber via a second fluid passage, and connected to the third valve chamber via a third fluid passage; and an actuator comprising a blocking element disposed in the fourth chamber and an actuator element disposed in the third valve chamber and coupled to the blocking element and configured to move the blocking element between a first position wherein the first passage is opened and the third passage is closed, and a second position wherein the first passage is closed and the third passage is opened.

Abstract: A pneumatic valve, includes an air chamber with a supply port to supply compressed air into the air chamber and one or more discharge ports for discharging compressed air from the air chamber. An actuator with a movable closing element and a shape memory alloy SMA element are provided in the valve. The SMA element deforms in response to a supply of electrical heating current and effects an activation of the actuator by movement of the closing element. When the actuator is in an activated state, the closing element blocks the supply of compressed air via the supply port is blocked. When the actuator is in a deactivated state, the closing element enables the supply of compressed air via the supply port. Upon deactivation of the actuator, the closing element is moved by a restoring force into the free setting. The valve includes a check valve with an elastic element.
