Pneumatic valve, and valve assembly having at least one such pneumatic valve

A pneumatic valve, having a housing in which is formed an air chamber with a supply opening for supplying compressed air, or another gas or fluid, into the air chamber, a connecting opening connected to the air chamber, and an actuator opening for connecting the air chamber to an actuator chamber;

• an actuator with a movable closing element being disposed in the housing;
• the closing element being configured with a tappet which penetrates the actuator opening, and a plate being formed on that end of said tappet that protrudes into the air chamber, a sealing element for closing the supply opening being disposed on said plate, and being formed with an elastic element which in an activated state of the pneumatic valve presses the plate in a direction toward the actuator opening;
• the actuator further comprising:
• a circuit board disposed in the actuator chamber;
• an activating element which is disposed in the actuator chamber and has an activating portion for acting on the tappet, and a bending portion connected to the activating portion and the circuit board;
• and
• an actuator element which is disposed in the actuator chamber and has a first end mechanically connected to the activating portion, and a second end mechanically and electrically connected to the circuit board;
• the actuator element in a non-energized state being configured to move the activating element to a first state in which it presses the tappet against the supply opening, and in an energized state to move the activating element to a second state in which the activating portion does not exert a force on the tappet in such way that the plate is pressed in the direction of the actuator opening by virtue of an effect of the elastic element,
• wherein a sealing collar which seals the air chamber in relation to the actuator chamber is disposed about the tappet between the plate and the actuator opening.
