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 tractor's rear wheels, with a control piston having a special 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 reserviors 7, 8 filled with a fluid with the predetermined pressure, is connected to front brake chambers 14, 15 of the tractor while another outlet port 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. The brake valve 18 is linked with a feed/exhaust valve 61 which is to feed and exhaust the pressure fluid to/from the rear brake chambers 27, 28. This valve 18 is equipped with a relay piston 52 to operate the feed/exhaust valve 61 and a control piston 56 which is to receive the pressure from the emergency line 39 at its one end and is provided with possibility of linkage with said relay piston 52.
