Abstract

PURPOSE: To decrease a pressure override by making an opening location to the valve seat side of a small hole formed to a poppet eccentric from an upper section of an axial core of the poppet.
CONSTITUTION: A poppet 4 is inserted into a sleeve 3 in a slidable shape, and contacted with a valve seat 6 by means of a spring 5 fitted to the back section. A fixed piston 7 is inserted into a hole made up to the inside in the poppet 4, space 8 is formed by the end surface and the hole and the poppet is opened to a contacting surface 4a at the valve seat 6 side through a small hole 9. When the poppet 4 separates from the valve seat 6, the pressure distribution 12 on the front of the poppet 4 lowers with the separation of the popper 4 from an axial core within a range of a contacting diameter of the poppet 4 and the valve seat 6. Thus, relief functioning pressure is made constant to the change of flow rate because an opening location of the small hole 9 is built up to the contacting surface 4a made eccentric from an upper section of the axial core of the poppet 4.
