連通する弁室を有する弁本体と、 この弁本体内の弁室の両側に一対の圧力室を形
成し、この一対の圧力室の圧力差により軸方向に
一体的に移動する一対のピストンと、 前記弁本体の弁室内で一対のピストンに連結さ
れ、この一対のピストンの移動に伴つて一対の低
圧流通口を連通させる切換状態と一方の低圧流通
口および高圧口を連通させるとともに他方の低圧

と を具備したことを特徴とする三方切換弁。[Claim for Utility Model Registration] A valve body having a valve chamber with which a high-pressure port communicates and a pair of low-pressure flow ports communicate; a pair of pressure chambers formed on both sides of the valve chamber in the valve body; a pair of pistons that move integrally in the axial direction due to a pressure difference between the pressure chambers of the valve body; and a pair of pistons connected to the pair of pistons in the valve chamber of the valve body, and communicating with the pair of low-pressure flow ports as the pair of pistons moves. A three-way switching valve characterized by comprising a valve body that can be switched between a switching state in which one low-pressure flow port and a high-pressure port are communicated with each other and a switching state in which the other low-pressure flow port is closed.
