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. |

1. A valve assembly, comprising:
a first valve assembly comprising a first housing and a first valve positioned within the first housing, wherein first and second ride height ports and an air spring port extend through the first housing, and wherein the first valve is moveable between a first ride height position, in which the first ride height port is in fluid communication with the air spring port, and a second ride height position, in which the second ride height port is in fluid communication with the air spring port; and a second valve assembly comprising:
a second housing, wherein an air supply port, first and second ports, and an exhaust port extend through said second housing; anda second valve positioned within the second housing and comprising a first surface in fluid communication with the air supply port and a second surface, wherein in response to movement of the first valve between the first ride height position and the second ride height position, the second valve moves between a first position, in which the second surface sealingly engages a portion of the second housing surrounding the first port to prevent fluid from flowing between the air supply port and the first port, and a second position, in which the second surface sealingly engages a portion of the second housing surrounding the second port to prevent fluid from flowing between the air supply port and the second port, and wherein the second 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 the air spring port, and an exhaust position, in which the air spring port is in fluid communication with the exhaust port. |
