してなる水栓。 In a faucet in which the valve element is composed of a fixed disk and a movable disk that is slidably superimposed on the fixed disk, a relief valve hole is provided in the partition wall that separates the primary side and the secondary side of the faucet body. A relief valve seat is formed on the primary side opening edge of the relief valve seat, and the relief valve seat is provided on the primary side of the relief valve seat opposite to the relief valve seat, and is always biased toward the relief valve seat side by a spring, and A piston that receives internal pressure and moves away from the relief valve seat when the pressure exceeds the spring force of the spring, and a relief valve body that moves forward and backward together with the piston and approaches and separates from the relief valve seat. The piston is provided with a recessed hole in the axial direction that communicates with the secondary side through a through hole penetrating the relief valve body at one end, and the other end of the recessed hole is connected to the primary side through a small passage. The concave hole is always biased toward the pressure chamber by the spring, and when the pressure inside the pressure chamber exceeds the spring force of the spring, the concave hole moves away from the pressure chamber. A faucet with a slidable auxiliary piston that operates automatically.
