Abstract

PURPOSE:To always make constant discharge pressure from the secondary side pipe, by providing a regularing valve which makes an up-and-down motion by hydraulic pressure of the secondary side pipe, in the connection hole connecting the primary and secondary side pipes. CONSTITUTION:Water flowing in from the primary side pipe 2 flows into the secondary side pipe 4 through the communication hole 6, and the primary side pressure P1 is evacuated by the communication hole 6 and becomes the secondary side pressure P2. And, when the secondary side pressure P2 has risen higher than expected pressure under the influence of the primary side pressure P1, the surplus pressure P2' reaches the hydraulic pressure chamber 8 through the through-hole 11 of the regulating valve body 9, and depresses the regulating valve body 9 against the elasticity of the spring 8. When this valve body 9 is lowered, the opening area of the communication hole 6 is reduced, and it is limited that water flows into the secondary side. In this way, since the valve body 9 is controlled by pressure itself of the secondary side, the secondary side pressure can be made constant at all times.
