HEIGHT CONTROL VALVE WITH SPRING RETURN ACTUATOR ABSTRACT OF THE DISCLOSURE A height control valve with a spring return actuator for use in an air spring suspension has a damping chamber, an air control chamber and an actuator con- trolled spring return housing with mutually perpendicu- lar lateral and axial bores. An actuator shaft extends into the damping chamber, the air control chamber and the lateral bore of the spring return housing. The spring return housing is rotatably mounted to the actua- tor shaft. A spring cup is reciprocably guided in the axial bore and is biased in contact with a flattened portion of the actuator shaft. The spring cup has two axially spaced cylindrical exterior surfaces of essen- tially zero draft angle and of slightly different dia- meter. The axial bore cylindrical surfaces are in registry with the spring cup cylindrical surface. The registering cylindrical surfaces of the spring cup and axial bore have dimensions of close correspondence to ensure a snug fit of the spring cup within the axial bore. A thin lubricating shim is provided between an actuator shaft and the interior walls of the air control chamber.
