Abstract

PURPOSE: To obtain a valve having both check valve function and neutral valve function by slidably providing a valve body, of which valve head is kept apart from a valve seat by a predetermined distance by means of power balance of two springs, in a valve hole communicating with a forced-in circuit and a main circuit.
CONSTITUTION: A block element 10 is equipped with a forced side through hole 11 and a main circuit side through hole 12. In a bottom part 15 of a cylinder hole 14 bored toward the forced side through hole 11 from an end face 13, a through hole 16 is bored to communicate with the forced side through hole 11, and its angular part 17 becomes a valve seat. Also the cylinder hole 14 communicates with the through hole 12 via a chamber 18, and at the same time a sleeve element 20, wherein a valve hole 22 is formed, is inserted into the cylinder hole 14. A valve body 26 equipped with a valve head 25, which can abut on and engage with a valve seat 17, is slidably inserted. And the valve body 26 has a valve head 25 separated from a valve seat 17 by a set distance by means of a balanced power of a first spring 28 pressing toward the valve seat and a second spring 29 pressing the valve body 26 against the first spring 28.
