According to the present invention, the second branch pipe branched from the main supply pipe 31, the first branch pipe 32 branched from the main supply pipe 31, the main supply pipe 31 into which the fluid is introduced, and which can be opened and closed according to a set pressure (33) and a piston valve means (34) subjected to an elastic force of the elastic member (35) to open and close the second branch pipe (33), wherein the piston valve means (34) is a second component. The cross-sectional area where the fluid in the main supply pipe 31 acts on the piston valve means 34 while the engine 33 is closed is such that the piston valve means 34 opens the second branch pipe 33. A fluid flow separator 30 is provided in which the fluid is smaller than the cross-sectional area acting on the piston valve means 34. The fluid flow separator of the present invention has an advantage in that the configuration of the flow line is easier because there is no room for high pressure unlike the prior art in the fluid flow line. In addition, since the cross-sectional area of the piston valve acting on the pressure of the incoming fluid is different at the time of opening and closing the valve, it is possible to adjust the opening and closing time of the valve by adjusting this.
