摘要： A trailer control valve comprises a valve electronic control port adapted to receive an electronic control signal; a valve pneumatic supply port unrestrictedly fluidly communicating with a first supply of a pneumatic fluid; a valve pneumatic control port normally proportionally fluidly communicating with a second supply of the pneumatic fluid based on a pressure representing a driver brake demand, the first supply of the pneumatic fluid being in an independent pneumatic circuit from the second supply of the pneumatic fluid; and a valve delivery port selectively fluidly communicating with at least one of the valve pneumatic supply port and the valve pneumatic control port based on the electronic control signal, the pressure representing the driver brake demand and a pressure of the first supply of the pneumatic fluid. A first pneumatic check valve includes a first check valve supply port fluidly communicating with the first supply of the pneumatic fluid; and a first check valve delivery port fluidly communicating with the relay valve pneumatic supply port. The first pneumatic check valve controls the fluid communication of the first supply of the pneumatic fluid with the relay valve pneumatic supply port based on the pressure of the first supply of the pneumatic fluid at the valve pneumatic supply port.

摘要： A valve system includes an isolation check valve delivering pneumatic fluid as a supply pressure, a double-check valve adapted to deliver a braking demand control signal of the pneumatic fluid based on a higher of a first braking demand in a first pneumatic braking circuit and a second braking demand in a second pneumatic braking circuit, and a control module. The control module is adapted to receive the supply pressure as a control module supply pressure of the pneumatic fluid, receive a control module control pressure of the pneumatic fluid based on the braking demand control signal, and deliver a control module delivery pressure of the pneumatic fluid based on the control module supply pressure and the control module control pressure. A park control module selectively transmits the pneumatic fluid at the supply pressure based on a park brake control signal.

摘要： A valve system includes a control module on a tractor portion of a vehicle adapted to receive a supply pressure as a control module supply pressure of the pneumatic fluid, receive a control module control pressure of the pneumatic fluid, and deliver a control module delivery pressure of the pneumatic fluid based on the control module supply pressure and the control module control pressure. A park control module selectively transmits the pneumatic fluid at the supply pressure based on a park brake control signal. A supply glad-hand fluidly communicates the selectively transmitted supply pressure of the pneumatic fluid to supply a brake on an associated trailer portion of the vehicle. A control glad-hand fluidly communicates the control module delivery pressure of the pneumatic fluid to control the brake on the associated trailer portion of the vehicle. An exhaust valve, which fluidly communicates with both the selectively transmitted supply pressure and the control module delivery pressure, exhausts the control module delivery pressure of the pneumatic fluid from the control glad-hand.

摘要： A trailer control valve for a tractor includes a body defining a supply port and first and second delivery ports. The supply port is configured for fluid communication with a fluid source on the tractor. The first and second delivery ports are configured for fluid communication with glad-hand connectors through which fluid is supplied from the tractor to a trailer for, respectively, releasing a parking brake and applying a service brake. The first delivery port is in fluid communication with the supply port. A relay valve is supported within the body and includes a valve member configured to move between positions preventing and permitting fluid communication between the supply port and the second delivery port. Pressure transducers in the body generate pressure signals indicative of fluid pressure at the delivery ports permitting detection of the presence of a trailer coupled to the tractor.

摘要： A valve includes at least one of an electrical port adapted to receive an electronic control signal and a pneumatic control port adapted to receive a pneumatic control signal. The valve also includes a pneumatic delivery port. The pneumatic delivery port is adapted to transmit a pneumatic fluid, based on the at least one of the received electronic control signal and the received pneumatic control signal, from a second independent source to control i) a second associated service brake and ii) delivery of the pneumatic fluid from a first independent source to control a first associated service brake.

摘要： A trailer control valve for a tractor includes a body defining a supply port and first and second delivery ports. The supply port is configured for fluid communication with a fluid source on the tractor. The first and second delivery ports are configured for fluid communication with glad-hand connectors through which fluid is supplied from the tractor to a trailer. A pressure sensing solenoid receives fluid signal from each of the first and second deliver ports and selectively passes fluid signal therefrom to a pressure sensor as a function of a brake control signal received by a controller that controls the pressure sensing solenoid.
