HEIGHT CONTROL VALVE WITH DUMP VALVE.

摘要

A height control valve (10) for an air spring suspension maitains the vehicle frame at a predetermined height by exhausting or adding presurized air to the air springs of the vehicle suspension in response to a sensor (16) that measures the position of the vehicle frame relative to a suspension member. A dump valve (18) is mounted to the height control valve so that the air springs may be completely exhausted of pressurized air when desired. The dump valve also prohibits the addition of pressurized air to the air springs when the dump valve is actuated.
