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 pressure governor includes a first valve that determines the introducing pressure and a second valve that determines the releasing pressure. A first valve receiving chamber in which the first valve is received and a second valve receiving chamber in which the second valve is received are formed independently from each other. Thus, there is no need to form the valves coaxially, and each valve can be easily fabricated with high accuracy by simple processing.

摘要： A protection valve includes: an input chamber into which air is introduced; a plurality of output ports through which air is discharged; and safety valves which open in response to a pressure increase on a primary side or close in response to a pressure decrease on a secondary side, the safety valves including a safety valve PV21 and a safety valve PV23. An air flow path from the input chamber is branched into a first branch line and a second branch line, and a time lag-creating valve having an opening pressure higher than the safety valve PV21 is provided at a upstream of the safety valve PV23 in the second branch line, so that the safety valve PV23 can open with a time lag after the safety valve PV21 opens, regardless of the difference between the opening pressures of the safety valves PV21 and PV23.
