Unbalanced inlet fuel tube for a fuel pressure regulator

A pressure regulator (10) includes a fuel tube (30) having an inlet end (35), an outlet end (180), and a fuel chamber (40). The outlet end defines a valve seat (70). A valve element (80) engages the valve seat in a closed position to prohibit flow of fuel from the inlet end to the outlet end. The va...

Beschreibung
Zusammenfassung:	A pressure regulator (10) includes a fuel tube (30) having an inlet end (35), an outlet end (180), and a fuel chamber (40). The outlet end defines a valve seat (70). A valve element (80) engages the valve seat in a closed position to prohibit flow of fuel from the inlet end to the outlet end. The valve element moves to an open position when pressurized fuel builds in the fuel chamber. A valve biasing member (90) biases the valve element towards the valve seat in opposition to the pressurized fuel in the fuel chamber. The fuel tube includes pressure differential creating structure (170) at the outlet end thereof to create a pressure differential around the valve element and cause unbalanced fuel flow at the outlet end to promote the valve element to move towards a certain location at the outlet end when the valve element moves to the open position.
