초록 ▼

A control valve assembly for use in a pump or injector of fuel injection systems is provided. A pump or injector body has a pumping chamber, and a valve chamber. The valve chamber defines a valve seat and has an axial guiding portion. A plunger is disposed in the pumping chamber. A valve body disposed in the valve chamber controls fuel. The valve body has a valve stem defining a seating surface. The valve body further has a valve guide in sliding engagement with the valve chamber guiding portion. The valve body is axially movable with respect to the valve chamber over a stroke range. The valve guide has an outer engagement surface that slidingly engages the valve chamber guiding portion with a clearance fit of at least about 5 micrometers in one embodiment. In another embodiment, the axial length of the engagement surface is at most about 7 millimeters. The reduced axial length and/or the clearance fit improve initial sealing performance and sealing performance over the life cycle of the product.

[ What is claimed is:] [1.] A pump for a fuel injection system, the pump comprising:a pump body having a pumping chamber, a fuel inlet for supplying fuel to the pumping chamber, an outlet port, and a valve chamber between the pumping chamber and the outlet port, the valve chamber defining a valve seat and having an axial guiding portion with a central axis;a plunger disposed in the pumping chamber;a valve body disposed in the valve chamber for controlling fuel, the valve body having a valve stem defining a seating surface, the valve body further having a valve guide in sliding engagement with the valve chamber guiding portion, and the valve body being axially movable with respect to the valve chamber over a stroke range between a closed position in which the seating surface engages the valve seat and an open position in which the seating surface is spaced from the valve seat to allow pressure relief, the valve guide having an outer engagement surface that slidingly engages the valve chamber guiding portion with a clearance fit of a first distance, the engagement surface having an axial length of a second distance, and wherein a ratio of the first distance to the second distance is at least about 5 to 7000;a valve spring biasing the valve body toward the open position;an armature at the valve body; anda stator near the armature and including an actuator operative to urge the valve body toward the closed position against the bias of the valve spring.
