An actuator arrangement () for an electromagnetically actuatable valve () is disclosed. The actuator arrangement () comprises: a housing having a first housing wall () and having a second housing wall () situated opposite the first housing wall (), a solenoid armature () which is arranged in the housing between the first housing wall () and the second housing wall () and which is movable between the first housing wall () and the second housing wall () along an axis (), wherein the solenoid armature () has a first axial armature end surface (), which faces toward the first housing wall (), and a second axial armature end surface (), which faces toward the second housing wall (), and the solenoid armature () is movable between a first position, in which the first armature end surface () makes contact with the first housing wall (), and a second position, in which the first armature end surface () has been moved away from the first housing wall (). The actuator arrangement () furthermore comprises a damping element (A,B) which is arranged on the second armature end surface () and which extends from the second armature end surface () in the direction of the second housing wall () and which is composed of an elastomer material, wherein the at least one damping element (A,B) makes contact with the second housing wall () both in the first position and in the second position of the solenoid armature (), and at least one stop element (A,B) which is arranged on the second armature end surface () and which extends from the second armature end surface () in the direction of the second housing wall () and which is composed of an elastomer material and which, in the first position of the solenoid armature (), has been moved away from the second housing () and, in the second position of the solenoid armature (), makes contact with the second housing wall ().

Actuator assembly for an electromagnetically actuatable valve

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.

Pneumatic solenoid valve

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.
