特徴とするフラッシング弁。A flushing valve that cooperates with a feed pump to exchange the fluid circulating in the closed circuit in which the hydraulic motor is mainly driven in the normal rotation by the fluid discharged from the hydraulic pump, a two-position switching valve connected to the other side fluid passage and switched by pilot pressure guided from one side fluid passage through which fluid mainly passes and the other side fluid passage through which used fluid of the hydraulic motor mainly passes; and a relief valve connected to the switching valve, the switching valve opening the relief valve and the other passageway in communication when the pressure in the one fluid passage is higher than the pressure in the other passageway. position, and when the pressure in the other side passage is higher than the pressure in the one passage, the switching valve switches to a closed position where communication between the IJ valve and the other side fluid passage is cut off. A flushing valve characterized by:
