Claims17
A discrete safety device comprising a pneumatic conductor, a pneumatic valve comprising an inlet port and an outlet port, a second valve, an enclosure within which said pneumatic valve is disposed and a vent pipe comprising an inlet end and an outlet end, said pneumatic conductor configured to be connected at a first end of said pneumatic conductor to said inlet port of said pneumatic valve and said pneumatic conductor configured to be connected at a second end to said second valve, said inlet end of said vent pipe is configured to pneumatically connect the exhaust port of said pneumatic valve to atmosphere external of said enclosure, said outlet end of said vent pipe is configured to be directed towards the ground while said discrete safety device is in use, and said second valve is configured to be pneumatically connected to an air brake system external to said discrete safety device, wherein opening said pneumatic valve vents pneumatic pressure from said pneumatic conductor to apply brakes of the air brake system, and closing said pneumatic valve terminates venting of the pneumatic pressure.
