摘要:
A fuel injector which includes an actuator having an electrical contact element, a plug, a fuel supply pipe, and an injection-molded housing part. The plug has a base body, an electrical connection element for an electrical connection with the electrical contact element of the actuator, and a rib which projects from the base body, the injection-molded housing part surrounding the electrical connection element of the plug and being injection-molded on the rib of the plug and the fuel supply pipe.
摘要:
The present invention relates to a fuel injection system for the direct injection of fuel into a combustion chamber of an internal combustion engine. At least one fuel injection valve is arranged on a cylinder head in a receiving bore in order to inject fuel into the combustion chamber. A fuel distribution line is provided for feeding the fuel to the fuel injection valve. A compensation element for a position compensation and/or tolerance compensation, is arranged in the radial direction between the fuel injection valve and the cylinder head and is arranged in the axial direction of the fuel injection valve between a first sealing element, sealing between the fuel injection valve and the cylinder head on a side facing the combustion chamber of the fuel injection valve, and a second sealing element, sealing between the fuel injection valve and the fuel distribution line. Further provided is a support ring, which is arranged between the fuel injection valve and the cylinder head and which provides support for the fuel injection valve in the axial direction on a step of the receiving bore and which has a clearance in the radial direction.
摘要:
An internal combustion engine includes a combustion chamber and a fuel injection valve that injects fuel directly into the combustion chamber, the fuel injection valve being situated in a cylinder head, and an annular sealing element being situated between the fuel injection valve and the cylinder head in order to seal the combustion chamber, and a shielding ring being situated between the sealing element and the combustion chamber in an axial direction of the fuel injection valve, the shielding ring being characterized in that it has a round cross-section or a cross-section that is rounded radially outward.
摘要:
A support element for the mutual support of a fuel injector in a valve seat, in particular of the valve seat of a cylinder head of an internal combustion engine, and of the fuel injector at a fuel distribution line has a clasp and thereon developed radially and axially deformable clips.
摘要:
A compensating element for supporting a fuel injector in a cylinder head of an internal combustion engine is configured in the form of an intermediate ring and situated between a valve housing of the fuel injector and a wall of a receiving bore of the cylinder head. The compensating element has webs at the intermediate ring which extend along the valve housing and on which support segments are affixed which surround the valve housing, thereby distancing the valve housing from the wall of the receiving bore.
摘要:
A leveling system for vehicles has at least one pressure-fluid-actuated work cylinder disposed between the vehicle body and the wheel suspension, a pressure fluid source and a pressure fluid sink for supplying pressure fluid to the actuator, and a proportional pressure regulating valve for controlling the flow of pressure fluid. The proportional pressure regulating valve has a main valve and a pilot control valve for controlling the main valve control slide into at least three slide positions; in the middle slide position the three controlled valve connections of the main valve are blocked off. To avoid abrupt changes in position of the vehicle body when the leveling system is put into operation, on the one hand a pressure holding valve that can be pushed open is disposed in the pressure fluid line from the work cylinder to the main valve, and on the other, a pressure-fluid-actuated centering device is provided in the main valve; no later than upon a pressure buildup by the pressure fluid source, this centering device fixes the control slide in its middle slide position, and it releases it again immediately after the opening of the pressure holding valve.
摘要:
A support element is provided for the mutual bracing of a fuel injector in a valve seat of a cylinder head of an internal combustion engine and a fuel-distributor line. The support element is formed such that the forces acting on the fuel injector act only in the axial direction and have no radial component.
摘要:
A compensating element for supporting a fuel injector in a cylinder head of an internal combustion engine has an annular design and is situated between a valve housing of the fuel injector and a wall of a receiving bore of the cylinder head. The compensating element includes at least two side pieces, which are supported on the fuel injector and the cylinder head.
