PROBLEM TO BE SOLVED: To eliminate the delay in response of brake control air of a pole trailer by a pure mechanical mechanism. SOLUTION: A relay valve 64 receives the brake command air from the upstream side of a control line 34 to supplement air from a supply line 36 to the downstream side of the control line 34. The transfer time of the brake command air to a relay emergency valve 50 related to the brake control mounted on a pole trailer 10 is shortened thereby. COPYRIGHT: (C)2010,JPO&INPIT |
