摘要: In a plate valve, particularly a cone spray valve, the valve gap, or respectively, seal gap (6) which is present in the open condition is not designed with parallel faces, but with cross-sectional areas which remain the same given increasing radius. This approach applies to a set from the interior outward. The advantage consists in the avoidance of cavitation and in the achievement of a low closing force for sealing the valve.

摘要: In a fuel injection valve including a flat fuel diffusion chamber provided between a valve seat member and an injector plate to widen radially outwards from an outer end edge of a valve seat bore, an annular step is formed on a ceiling surface of the fuel diffusion chamber so that a level of the ceiling surface is gradually lowered radially outwards, and fuel injection orifices are disposed immediately below the step and at a distance from an inner peripheral wall of the fuel diffusion chamber. Thus, a fuel spread radially in the fuel diffusion chamber is allowed to collide with the annular step, leading to an enhancement in fuel diffusing effect, so that it is possible to further promote the atomization of the fuel injected from the fuel injection orifices and to form more stable fuel spray forms.

摘要: A fuel injector for fuel injection systems of internal combustion engines includes a valve needle and a valve-closure member mechanically linked to it, which cooperates with a valve-seat surface situated in a valve-seat member to form a sealing seat, and at least one swirl-producing element which is situated upstream from the sealing seat in the valve-seat member. One or more swirl channels which are open toward the upstream side of the valve-seat member are incorporated into the upstream side of the valve-seat member as a swirl-producing element.

摘要: A fuel injector comprising an outer valve needle provided with a bore, an inner valve needle slidable within the bore, the outer and inner valve needles being engageable with first and second seatings respectively to control the supply of fuel from the fuel injector. The inner valve needle includes a passage which communicates with a sac chamber located downstream of the second seating, whereby movement of the outer valve needle away from the first seating causes fuel to flow through the passage into the sac chamber such that fuel pressure within the sac chamber causes the inner valve needle to lift away from the second seating.

摘要: A fuel injector for delivering fuel to a combustion space comprises a valve needle which is movable within a bore provided in a nozzle body and which is engageable with a seating to control the supply of fuel from the bore. The injector further comprises a return flow passage for permitting fuel to escape from the bore to a low pressure drain upon initial movement of the valve needle away from its seating. The injector may include a cover member which defines, together with the nozzle body, a part of the return passage for fuel through which fuel flows, in use, to reduce the temperature of the nozzle body.

摘要: A fuel injector seat for a fuel injector assembly, and more particularly for a high-pressure fuel injector assembly, having a number of features for minimizing the formation of combustion chamber deposits on the seat, providing a selected finish on a needle-sealing portion, and reducing sac volume. These features include positioning a transition portion between the needle-sealing portion and an orifice portion, positioning a sharp edge at the outlet of the orifice portion, and applying a coating to certain surfaces of the seat. This invention also relates to a fuel injector seat and method of manufacturing the fuel injector seat, and a method of evaluating when the transition portion is required between the orifice and needle-sealing portions for a particular seat arrangement.

摘要: A fuel-injection valve, in particular, a high-pressure injection valve, for injecting fuel directly into a combustion chamber of a mixture-compressing internal combustion engine with externally supplied ignition is distinguished by the fact that a guide and seating area formed by three disc-shaped elements is provided at a downstream end of the valve. A swirl element is embedded between a guide element and a valve seat element. The guide element is used to guide a valve needle which passes through it and can move in the axial direction, while a valve closing segment of the valve interacts with a valve seat surface of the valve seat element. The swirl element has an inner opening area with multiple swirl channels. The three disc-shaped elements are permanently connected to each other, forming a positive-locking joint.

摘要: A fuel injection valve having a swirl disk, located downstream from a valve seat (15), that is made of at least one metallic material and has at least two swirl channels emptying into a swirl chamber, with all layers being built up by electrodeposition (multilayer electroplating) so that they adhere firmly to each other. The swirl disk has an upper layer that includes multiple material areas separated from each other by opening structures. The material areas of the swirl disk rest against a valve seat body containing the valve seat. The fuel injection valve is especially suitable for injecting fuel directly into the combustion chamber of a mixture-compressing internal combustion engine with externally supplied ignition.
