FLOW THROUGH PRESSURE REGULATOR

摘要

A flow through pressure regulator (10) as may be used in a fuel delivery system for a motor vehicle has a contained, but floating ball valve. The ball valve (64) opens and closes a central passageway through the diaphragm of the regulator. The diaphragm (40) divides the interior of the regulator into 2 chambers, both of which have fuel. A retainer means (76) supports the ball and allows both axial and radial movement and coupled with a small bias spring (86) seating in a bore, the ball functions to automatically seat itself. The small bias spring does not interfere with the ball valve seating itself.
