Abstract

PURPOSE:To prevent the relative vibration between a spool and a valve body by a structure wherein a rubber elastic ring arranged between the valve body and the spool is applied with pressurized oil sent from a hydraulic pump. CONSTITUTION:A circumferential groove 3 is provided at the right end of the spool 2, which is fitted in the inner diametral part of the valve body 1 with a narrow clearance. An axial groove for controlling pressurized oil 22A is communicated with the groove 3 through a slit 5. Furthermore, the circumferential groove 3 and a discharge side annular chamber 7 are communicated with each other through a clearance delta3 larger than the fitting clearance delta1 of the spool 2 into the valve body 1 at its pressure side. The rubber elastic body 6 is assembled into the circumferential groove 3 and pressed simultaneously against the side wall 3A of the circumferential groove 3 and against the inside surface 1A of the valve body 1 in response to the pressure change of the pressurized oil, resulting in applying frictional resistance between the spool 2 and the valve body 1.
