ルブ。 A valve that is connected to the pump discharge side to control the fluid pressure at a constant pressure, and includes a valve body provided with a suction port waterway and a discharge port waterway, and a valve body that is slidably housed within the valve body and has a discharge port waterway. A throttle valve for controlling pressure at a constant level, and a balance piston provided via a valve stem on the opposite side of the throttle valve, are arranged so as to supply fluid from a suction port waterway to an intermediate portion between the throttle valve and the balance piston. The pressure is adjusted to a constant pressure by allowing fluid from the suction port waterway to flow into the control valve body and the piston chamber on the end face side of the balancing piston, and discharging a portion of the pressure water in the piston chamber to the outside of the valve body. an adjustment device; a check valve having a small hole in a side wall of the valve body, one of which communicates with the suction waterway side of the valve body and the other communicating with the discharge waterway side, and a valve body having a guide between the small holes; A constant pressure control valve characterized in that when the throttle valve is closed, water is allowed to flow from the inlet waterway side to the outlet waterway side until the pressure on the outlet waterway side reaches a maximum value.
