<p>PURPOSE: To simplify air pressure piping by connecting engine/transmission side air pressure piping to chassis side air pressure piping of an air pressure source, arranging a protection valve in the chassis side air pressure piping, and arranging a solenoid valve in the engine side air pressure piping. CONSTITUTION: In a hose 21, an engine side air pressure pipe 18 of exhaust brake control cylinders (E, B, C, C) 14, 14 and a transmission side air pressure pipe 19 of a clutch booster 15 are connected to a chassis side air pressure pipe 20 of an air tank 17. A protection valve 22 is arranged in this chassis side air pressure pipe 20, and a solenoid valve 23 is provided in a part of a three-way joint 24 of this engine side air pressure pipe 18, to apply a pressure of the air tank 17 to the cylinders E, B, C, C14, 14. Thus, as compared with the ordinary case, each one quantity is saved respectively of the hose 21 and air pressure pipe 20.</p> |
