An antiskid device comprises an antiskid valve which in its braking position establishes a passage between the brake control line and the brake cylinder and in its skidding position establishes a passage between the brake cylinder and a pressure relief line. A valve responsive to skidding of the vehicle connects a control chamber in the antiskid valve to a source of pressure-medium in the braking position and to a pressure relief line when skidding occurs. A normally open monitor valve is in the pressure relief line and this valve is closed in response to a delay exceeding that of a normal skidding action. A throttle restriction bypassing the skid responsive valve supplies pressure-medium to the control chamber so that the antiskid valve can be returned to the braking position in the event that the skid responsive valve should for any reason remain in the skidding position. |
