摘要： A fuel injection valve for internal combustion engines has a valve body in which a pistonlike valve member is longitudinally displaceably disposed in a bore. The valve member is surrounded, over at least part of its length, by a pressure chamber that can be filled with fuel. On its end toward the combustion chamber, a valve seat is embodied in the bore, on which seat the valve member comes to rest with a valve sealing face in a closing position, so that the pressure chamber is disconnected from at least one injection opening located downstream of the valve sealing face. First and second parallel annular grooves are formed in the end region of the valve member disposed axially toward the valve seat and the valve sealing face is disposed between these two annular grooves.

摘要： A method of making a metering orifice disc from a work piece is disclosed. The work piece has a first surface spaced apart from a second surface over a first distance. The metering orifice disc has an outer diameter from 4 to 6 millimeters with at least one orifice disposed through the metering disc of about 75 to 150 microns in effective diameter. The method can be achieved by removing material from one of the first and second surfaces of the work piece to define a recessed surface between first and second walls, the recessed surface being located between the first and second surfaces of the work piece; and forming an orifice in the recessed surface proximate a shortest distance between the first and second walls to define two channels that extend towards the longitudinal axis, the orifice extends through the recessed surface to one of the first and second surfaces. A method of making a valve seat is also described.

摘要： Using a swirl type fuel injection valve, a concentrated spray area and a thin spray area are formed, the positions thereof are adjusted, and the spray is made to conform to the geometric shape of the engine and mounting position of the fuel injection valve, so as to reduce the fuel consumption and control the unburnt components in exhaust gas. The fuel injection valve is so constructed that a step is formed on the injection hole opening of the fuel injection valve, so as to provide two or more edge transition portions at the injection hole opening, resulting from the step, and the line connecting the edge transition portions forms an oblique angle relative to the wall formed by the step perpendicular to the injection hole center axis and the angled wall.

摘要： A fuel injector including a control valve arrangement for controlling fuel pressure within a control chamber comprises a control valve member which is movable between a first position in which the control chamber communicates with a source of high pressure fuel and a second position in which the control chamber communicates with a low pressure fuel drain and communication between the control chamber and the source of high pressure fuel is broken. The control valve arrangement includes a restricted flow path for restricting the rate of flow of fuel from the source of high pressure fuel to the control chamber when the control valve member is moved towards its first position. The provision of the restricted flow path prevents unbalanced hydraulic forces acting on the control valve member when it moves towards its first position, which can otherwise lead to valve needle dither between injecting and non-injecting states.
