Claims

[Scope of utility model registration request]

A part of the valve body is a valve housing block, and a secondary pressure chamber on the plunger side and a secondary pressure chamber on the valve device side are formed on each side wall side of a partition wall provided in the axial center of the valve housing block, and the valve A valve device including a valve seat and a valve body is provided on the partition surface of the device side secondary pressure chamber, a primary side inflow path and a secondary side outflow path leading to the valve device are formed in the valve body, and the valve housing The valve element of the valve device is fixed to a frame-shaped support that penetrates the partition wall of the block and is movable back and forth in the axial direction of the valve housing block. In a pressure regulating device connected to a plunger that opens the valve device against the pressure on the secondary side by force, the frame-shaped support body is loosely fitted into the partition wall of the valve housing block to connect the secondary pressure chamber on the valve device side and the plunger. A pressure regulating device for high-pressure liquid, characterized in that a passage is formed between the side secondary pressure chambers, and the secondary side outflow path is directly connected to the plunger side secondary pressure chamber.
