りとを設けたことを特徴とする油圧パイロット切換弁。When the pilot pressure oil supplied to the pressure receiving chamber of the valve body flows through an orifice provided in a spool built into the valve body, the pressure difference between before and after the orifice causes the spool to move inside the valve body under the force of a spring. In a hydraulic pilot switching valve that moves in the axial direction against the pressure and switches the oil passage within the valve body, a hydraulic pilot switching valve has a valve that allows pilot pressure oil to flow into the valve body pressure receiving chamber side of the spool before switching the oil passage. 1. A hydraulic pilot switching valve, characterized in that it is provided with an oil passage hole having a larger diameter and a throttle having a smaller diameter than the passage hole through which pilot pressure oil flows after switching the oil passage.
