WIPO Patent Application WO/2021/200645
Kind Code:
A1
Abstract:
This purge system comprises a main tank; a compressor; an air dryer including a purge valve; an indicated pressure supply part that supplies an indicated pressure and stops the supply of the indicated pressure according to a tank pressure which is the pressure within the main tank; and a control unit that stops air supply by the compressor when the tank pressure reaches a first pressure value, which is smaller than the value of the tank pressure at which the indicated pressure supply part begins to supply the indicated pressure, on condition that at least one of the following is satisfied: a prescribed operation is detected; it is determined that an air supply amount to the air dryer by the compressor during a predetermined period of time is less than a first threshold; and the duration of time from a time at which the supply of the indicated pressure was started until a time at which the supply of the indicated pressure was stopped is equal to or greater than a reference time duration.
