摘要： An apparatus for controlling the lift of a valve member in a flow control valve comprises an end stop assembly having at least two pieces, a plunger with one end interposed between these pieces and biasing members that urge the pieces into contact with the plunger. The plunger is movable by an actuator to thereby move the pieces of the end stop assembly from a first position in which the pieces of the end stop assembly form a first surface for contacting the valve member to a second position in which the pieces form a second surface that comes into contact with the valve member when the valve member is lifted from its seated position, to thereby allow different discrete lifts of the valve member.

摘要： An integrally formed cylinder 2 having alternating magnetic 2b, 2d and non-magnetic portions 2a, 2c, 2e for use in an injector. At least two solenoid coils 12, 14 are disposed about the cylinder 2 to urge an armature 4b to open and close a valve 4a. The non-magnetic portions 2a, 2c, 2e of the cylinder 2 ensure that magnetic paths for opening and closing the valve are magnetically insulated from each other. The integrally formed cylinder 2 is leak proof and thus does not require O-rings or other sealing structures for sealing the fuel path 4e, 4f from the solenoid coils 12, 14. A protrusion 2z may be formed on the cylinder 2 to assist in positioning the solenoid coils 12, 14.
