High pressure regulator for hydrogen fuel cell electric vehicle

摘要

The present invention relates to a high-pressure regulator for regulating a fuel supply pressure of a vehicle, comprising: a hollow body (10) having a plurality of ports formed in an axial direction and a radial direction; A piston 20 received in the hollow of the body 10 so as to be vertically movable; A seat (30) received to form an orifice (31) in the hollow of the body (10); And a spool (40) installed to pass through the piston (20) and the seat (30) and performing up and down movement for controlling the pressure. Accordingly, it is possible to realize a slim and compact structure while maintaining good operational reliability and durability so as to be compatible with mounting on a hydrogen fuel cell vehicle, thereby contributing to cost reduction and fuel efficiency improvement.
