The invention relates to a heating device () for a tank () of an exhaust gas aftertreatment agent system, having a carrier () and having a plurality of heating elements () arranged on the carrier (). According to the invention, the carrier () has a plurality of carrying elements (), which are connected to one another in an articulated manner, and at least one spring element (), which applies a spring force to at least two of the carrying elements (). The carrier () is thus formed to be flexible or deformable overall, wherein the carrier is forced into a final shape by the spring element.

Heating device for a tank of an exhaust gas aftertreatment system, tank device

A heat sink () for an injection/metering valve () has a coolant chamber () which is designed for receiving a fluid coolant. The coolant chamber () has at least one inlet () for supplying the coolant and at least one outlet () for removing the coolant. The at least one inlet () and/or outlet () has a pipe segment () which extends with one end into the coolant chamber (). The coolant-chamber-side end of the pipe segment () is bevelled, and therefore the coolant-chamber-side end of the pipe segment () is in contact at at least one point along its circumference with a baffle () arranged in the coolant chamber (), and the end of the pipe segment () is spaced apart at another point along its circumference from the baffle ().

Heat sink for an injection/metering valve

The invention relates to an injection device (), designed in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve needle (), an injection chamber () having at least one injection opening (), and a control chamber (). The injection device () is designed such that a pressure differential between the injection chamber () and the control chamber () brings about a displacement of the valve needle () between an open position in which a fluid flow through the injection opening () from the injection chamber () is released, and a closed position, in which the injection opening () is closed off. The injection chamber () and the control chamber () are hydraulically connected to an inlet (), such that a pressure rise in the inlet () results in a pressure rise in the injection chamber (), and a pressure rise in the control chamber () delayed in time relative to the pressure rise in the injection chamber (), and said pressure differential brings about a displacement of the valve needle () from the closed position into an open position.

Injection device for introducing a urea solution into the exhaust tract of an internal combustion engine

The invention relates to an injection device, in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve unit which comprises a valve needle, an injection chamber having at least one injection opening, and a control chamber, wherein the injection device is designed so that a pressure differential between the injection chamber and the control chamber brings about a displacement of the valve needle between an open position in which the valve needle releases a fluid flow through the injection opening, and a closed position in which the valve needle closes off the injection opening. The injection device also has a pump unit integrated in the injection device. The pump unit is designed so as to draw in fluid from the fluid inlet during operation and to provide said fluid to the valve unit under increased pressure.

Injection device

Disclosed is a fuel injection device comprising a housing and a valve element disposed therein and cooperating with a valve seat located in the area of at least one fuel discharge port. The valve element is composed of several parts while at least two parts of the valve element are coupled to each other via a hydraulic coupler.

Fuel injection device for an internal combustion engine using direct fuel injection

The invention relates to a fuel injector which has a retaining body and an injection nozzle nut. An expansion sleeve, which can be supplied with hydraulic fluid, is provided around the periphery of the fuel injector, in particular around the periphery of the retaining body. The expansion sleeve includes at least one pocket-type recess, which can be supplied with hydraulic fluid.

Fixing element for an expansion sleeve

The invention relates to a fuel-injection system (), in which a rail () is provided for each injector between a high-pressure fuel pump () and said injectors ().

Fuel injection system with a plurality of pressure reservoirs

The invention relates to a common rail injector for injecting fuel in a common rail injection system of an internal combustion engine, having an injector housing, which communicates with a central high-pressure reservoir and in which a nozzle needle is axially displaceable in order to adjust the injection as a function of the pressure in a control chamber, and having a sealing element, which is disposed in an annular chamber that is provided between a valve element and the injector housing. In addition to the sealing element, a support device is disposed in the annular chamber between the valve element and the injector housing.

Common rail injector

A solenoid valve for a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine having an injector body which includes an electromagnet. An armature group of the solenoid valve may be actuated by this electromagnet to relieve the pressure in a control chamber, so that a nozzle needle/tappet assembly in the injector body implements an opening/closing movement. The armature group includes a first and a second armature part. The first armature part and the second armature part are joined to one another by an insert-and-twist connection, one of the armature parts being enclosed by an armature guide which includes anti-rotation elements.

Solenoid valve comprising a plug-in/rotative connection

A solenoid valve having a magnet assembly and an injector body connected thereto, the magnet assembly and the injector body being joined together using a crimped retaining ring as the connecting element.

Solenoid valve

The invention relates to a common rail injector for injecting fuel in a common rail injection system of an internal combustion engine, having an injector housing which communicates with a central high-pressure reservoir and in which a nozzle needle that cooperates with a valve piston which is guided in a valve piece is axially displaceable. To increase the service life of the injector, the end toward the nozzle needle of the valve piston or of a thrust rod triggered by the valve piston is guided coaxially to the axis of symmetry of the nozzle needle.

A high-pressure fuel system for internal combustion engines, having a housing that contains two high-pressure bodies. The high-pressure bodies rest with contact surfaces at least indirectly against each other and are pressed against each other by means of a tensioning device. A supply conduit is embodied in the high-pressure bodies, which carries highly pressurized fuel and passes through the contact surfaces of the two high-pressure bodies. A sealing film is disposed between the two high-pressure bodies, which encompasses the passage of the high-pressure conduit and thus assures a favorable seal.
