にしたことを特徴とす乞低値選択油圧回路。In the low value selection circuit for two hydraulic signals, there are two pilot chambers that receive input signals through orifices on the outside of the first and second lands that are directly connected to each other, and a balanced land in the pilot chamber. A first and second port for receiving an input hydraulic pressure signal and a third port for outputting a low-value hydraulic signal of the human-powered hydraulic pressure signal are provided inside the first and second lands. The input hydraulic pressure signal is transmitted to the pilot chamber through the same port and orifice, and the land is operated by the hydraulic pressure difference between the pilot chambers, so that the port to which the hydraulic pressure signal is transmitted is self-closed. Features a low value selection hydraulic circuit.
