Abstract

PURPOSE: To miniaturize the control valve by sliding a spool provided with variable orifice by a pilot hydraulic pressure in the direction which is perpendicular to the direction of the hydraulic operating fluid for said valve of hydraulic pressure elevator and the like, and controlling the amount of the hydraulic operating fluid.
CONSTITUTION: The hydraulic operating fluid which is applied on the upper surface of a valve case 41 flows to the lower surface side of the valve case 41 via an inlet port 44, a valve chamber 42, outlet ports 45a and 45b, and a through hole 51. At this time the amount of hydraulic operating fluid flowing in the valve chamber 42 is controlled by sliding the spool 43 by the pilot hydraulic pressure which is applied from an oil introducing port 50, and by varying the opening area of a variable orifice 47 provided in said spool 43. Since the spool 43 is slidden in the direction which is perpendicular to the hydraulic operating fluid flowing direction and the opening area of the variable orifice 47 is varied, the spool 43 can be made compact, and its diameter also can be made short. Therefore, the control valve also can be made compact.
