PROBLEM TO BE SOLVED: To provide a pressure control valve which prevents deterioration of pressure control characteristics. SOLUTION: This type of pressure control valve has a valve element 27, a valve cylinder 25 in which the valve element 27 is seated at a valve seat 33 for blocking a valve hole 31, and a spring 49 for energizing the valve element 27 in a seating direction. An inflow port 29 is formed on the valve cylinder 25 for introducing fluid from a peripheral wall of the valve hole 31. The valve element 27 has a first guide part 35 locate on the valve element side in respect to the inflow port 29, and a second guide part 37 on the opposite side to inflow port 29. A groove 47 through which fluid passes is formed on the first guide part 35. |
