摘要： An object of the present invention is to allow a vehicle to run in the case where an air compressor connected to an input port fails so as to cause air leakage from the location of the failure, by preventing air in a parking brake circuit from leaking from the failure location through a bleed air flow path. In order to achieve the object, a multi-protection valve includes: a communication passage for communicating between an input chamber and a service output port so as to bypass a pressure control valve provided in correspondence with the service output port, the communication passage having a check valve for preventing air from flowing from the service output port into the input chamber and a throttle for restricting the air flow rate; and a bleed air flow path for communicating between the input chamber and the parking output port so as to bypass pressure control valves, the bleed air flow path having a second check valve for preventing air from flowing from the input chamber to the parking output port. The multi-protection valve further includes a third check valve provided between the input chamber and an input port to prevent air from flowing from the input chamber to the input port.

摘要： A reservoir flange portion is formed in a leg portion of a reservoir so as to protrude beyond a seal member in a direction of a cylinder body and to extend radially outward. An annular retaining member, which has an outer diameter larger than the outer diameter of the reservoir flange portion and an inner diameter smaller than the outer diameter of the reservoir flange portion, is interposed between an engaging surface of the reservoir flange portion of the reservoir and an engaging surface of the seal member. By this arrangement, retention of the reservoir relative to the seal member and the cylinder body is markedly improved by means of the retaining member having an outer diameter larger than the outer diameter of the reservoir flange portion.
