Abstract:
Electropneumatic solenoid valve includes an electromagnetic actuator with an energizable coil and a solenoid armature movable relative to the coil, an air chamber with three air channels, and a valve member. The three air channels include first and second air channels and a control air channel. The valve member, in a first closed position, closes the first air channel and releases the second air channel and which, in a second closed position, closes the second air channel and releases the first air channel. The valve further includes a driver movable in a first and second actuating directions and that connects the valve member to the solenoid armature, a driver-pretensioning spring arranged between the driver and the solenoid armature, to provide a pretensioning force to the driver, and a restoring spring between the driver and the electromagnetic actuator to provide a restoring force to the driver against the driving direction.
