    摘要： A switching valve includes main valve constituted of a five-port electromagnetic switching valve settable to a closed-center position, and a residual pressure exhaust valve including an exhaust valve cavity communicating with a supply port of the main valve and two exhaust ports, two residual pressure discharge flow paths respectively communicating with the exhaust ports, two exhaust valve elements placed inside the exhaust valve cavity and driven by pressure air from the supply port to open and close the residual pressure discharge flow paths, and a release spring that biases the exhaust valve element in a direction to open the residual pressure discharge flow paths. While the pressure air is not supplied into the exhaust valve cavity through the supply port, the exhaust valve element opens the residual pressure discharge flow paths so as to discharge residual pressure from the exhaust port, and when pressure air is supplied into the exhaust valve cavity the exhaust valve element closes the residual pressure discharge flow path, and hence the residual pressure is not discharged from the exhaust port.

    摘要： A lift axle control module is disclosed that is simpler than prior art lift axle control systems, and does not require cycling the input pressure to the regulator. The module includes a housing fluidly connected to a first pressurized air supply and having one chamber with a load bladder port, a second chamber with a lift bladder port, and a common vent port. A pilot pressure is selectively provided for switching the module between the retracted and deployed modes. When the control module is set to the retracted mode, the lift bladders are pressurized to the system pressure, and the load bladders are vented. When the control module is set to the deployed mode, the lift bladders are vented and the load bladders are inflated and maintained at the regulated pressure.
