Abstract: 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.

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.

Abstract: A flow through pressure regulator apparatus and method for directing a flow of fuel and reducing valve seat wear within a fuel system. Present invention includes a lower housing having fuel inlet where fuel flows through the fuel inlet and communicates with a valve assembly and valve biasing member. The valve assembly comprises a lower and upper valve member where the lower valve element contains a plurality of fuel passages. The valve biasing member permits or inhibits fuel flow through the lower valve member by opening and closing an upper valve member. The valve biasing member comprises a flat disk having at least two reticulated concentric rings coupled by at least one bridge. The fuel flows past an open upper valve member through the plurality of fuel passages that encircle the lower valve member to the valve biasing member. The valve biasing member then diffuses the flow of fuel. A fuel cover directs the flow of fuel from the valve biasing member to the fuel outlet.

Abstract: A method and system controls motion of an armature 112 of a fuel injector 100. The armature moves between an open coil 118 and a close coil 116 of the injector. Acceleration current of a certain polarity is applied to the open coil 118 with the armature disposed at the close coil 116. De-latching current of a polarity opposite of the certain polarity is applied to the close coil 116 to release magnetic latch on the armature thereby accelerating movement of the armature towards the open coil 118. Deceleration current is applied the close coil 116 thereby decelerating the armature prior to reaching the open coil. Latching current of the certain polarity is applied to the open coil 118 prior to or just after impact of the armature 112 with the open coil 118 to magnetically latch the armature to the open coil 118 thereby reducing bounce of the armature at impact.
