Abstract
PURPOSE: To control the pressure of a pressure fluid used in a pneumatic brake of a tractor during the tractor's running alone and coupled with a trailer by equipping a relay valve, which is to supply the pressure fluid to the brake actuator at the tractor's rear wheels, with a relay piston having a special stepped construction.
CONSTITUTION: An outlet port 9 of a brake valve 1, which is equipped with a brake pedal 2 to be operated by an operator and is connected to reservoirs 7, 8 filled with a fluid with the predetermined pressure, is connected to front brake chambers 14, 15 of the tractor while another outlet 16 is connected to a pilot port 19 of a relay valve 18 and a pilot port 22 of another relay valve 21 which is to transmit brake pressure to the trailer. A relay piston 52 of this relay valve 18 is formed with a step, where the smaller peripheral part 54 shall receive the brake pressure and the wider peripheral part 58 the brake pressure from a service line 32. This relay piston 52 works to control a feed/exhaust valve 60 which is to feed and exhaust the pressure fluid to/from the rear wheel side.
