Abstract:
A height control valve assembly having a housing with an air supply port, first and second ports, and an exhaust port. A valve positioned in the housing has a first surface in fluid communication with the air supply port and a second surface. The valve moves between first and second positions, in which the second surface sealingly engages a portion of the housing surrounding the first and second ports, respectively, to prevent fluid from flowing between the air supply port and the first and second ports, respectively. The valve is moveable from either of the first and second positions to a fill position, in which the air supply port is in fluid communication with one of the first and second ports, and an exhaust position, in which one of the first and second ports is in fluid communication with the exhaust port.
