Fuel pressure regulator for vehicle

摘要

In one embodiment, a fuel pressure regulator includes a housing defining a fuel inlet and a fuel outlet, and a ball in the housing is movable between a closed configuration, wherein fluid communication between the inlet and outlet is blocked, and an open configuration, wherein fluid communication between the inlet and outlet is not blocked. Fuel pressure urges the ball toward the open configuration. A spring in the housing is engaged with the ball to urge the ball toward the closed configuration. Also, a ball holder is engaged with the ball and spring and is oriented to receive fluid pressure from the inlet when the ball is moved away from the closed configuration. Fluid pressure from the inlet acts directly against the ball holder as well as against the ball to assist moving the ball toward the open configuration.
