Technical Examples
  1. The present invention provides a hydraulic control valve and a power steering apparatus using the same in which chamfer portions are provided only on throttle portions between oil supply chambers and first oil feed chambers and between the oil supply chambers and second oil feed chambers, or only throttle portions between oil discharge chambers 11 and the first oil feed chambers and between the oil discharge chambers 11 and the second oil feed chambers. With this design, even if six or more oil grooves of each of a valve body and a valve spool are disposed at equal distances from one another, when the minimum flow rate to be controlled is reduced as small as possible, a distribution amount for one portion where the flow rate is controlled can be doubled as compared with a conventional structure, it is possible to stabilize the hydraulic characteristics in a region where the flow rate to be controlled is minimum, and to eliminate the discontinuity of the hydraulic characteristics.
