Definitions
- the respective injection valve may be suited to dose fluids under very high pressures.
- the pressures may be in case of a gasoline engine, for example, in the range of up to 200 bar and in the case of diesel engines in the range of up to 2000 bar.
- a gasoline engine for example, in the range of up to 200 bar
- diesel engines in the range of up to 2000 bar.
- the hardness of the upper retainer was increased by applying special hardening processes.
- this was only possible by using specialized materials for the upper retainer, which are expensive, and by applying additional steps in the production process.
- the upper retainer had to be provided with special geometries in order to increase the fluid flux of the fuel, and thereby to minimize the sticking phenomena.
- the injection nozzle 34 may be, for example, an injection hole. However, it may also be of some other type suitable for dosing fluid.
- the valve assembly 11 is provided with an actuator unit 36 that is preferably an electro-magnetic actuator.
- the electro-magnetic actuator unit 36 comprises a coil 38, which is preferably arranged inside the housing 16. Furthermore, the electro-magnetic actuator unit 36 comprises the armature 21.
- the housing 16, the inlet tube 12, the valve body 14, and the armature 21 are forming an electromagnetic circuit.
- the actuator unit 36 is electrically energized by a connection means 15, which, in turn, may be coupled to an external plug connector.
- the armature 21 is designed to be coupled to the upper retainer 23 when the valve needle 20 is actuated to leave the closing position, and it is designed to be decoupled from the upper retainer when the valve needle 20 is actuated to move to the closing position.
- the cavity 18 comprises a fluid outlet portion 40 which is arranged near the seat plate 32.
- the fluid outlet portion 40 communicates with a fluid inlet portion 42 which is provided in the valve body 14.
- Fig. 1A shows the main spring 24, the upper retainer 23, the armature 21, and the tubular valve needle 20 of the embodiment of Fig. 1 in more detail.
- Fig. 2 shows another embodiment of the injection valve.
- the upper retainer 23 is made in the form of a guide bush, arranged like a collar around the valve needle 20, and the anti-bounce means 22 is made in the form of a permanent magnet.
- This permanent magnet is fixedly coupled to the valve body 14. Fixing may be achieved, for example, by welding to an inner surface of the valve body 14 in the area of the fluid inlet portion 42 or by providing a step 44 at the fluid inlet portion 42 and coupling the permanent magnet to said step 44.
