Definitions

  • the invention relates to an injection valve for fuel injection in a Internal combustion engine, especially in a diesel engine, with a Holding body in which a first channel is formed, with a Holding body attached nozzle body of an injection nozzle, in which a second channel is formed, which is connected to the first channel and with this forms a fuel supply for the injection nozzle, with a Closing mechanism for closing the injector, and with a sealant for sealing the junction between the first and the second channel.
  • the invention further relates to a Sealant according to the preamble of claim 19 for sealing the junction between two channels.
  • An injection valve of the type mentioned is used in internal combustion engines like gasoline engines or diesel engines used to the Fuel directly into the cylinder of the internal combustion engine or indirectly to be injected into a pre-chamber connected to the cylinder.
  • the injection valve should be as precise as possible Fuel as a finely divided mist in the Insert the cylinder or the prechamber.
  • the injector the injection valve by a closing mechanism, for example a mechanically pre-tensioned nozzle needle, closed, the for fuel injection, the injector opens briefly, the escaping fuel is atomized through the injection nozzle. So despite a sufficient amount of fuel is injected during the short injection period and the fuel is atomized as finely as possible in the known Injection systems, such as the common rail injection system, the fuel with a pressure of 1400 bar and more the injector fed.
  • the well-known injection valves can be installed constructed in several parts. So the actual injector is shared with the locking mechanism attached to a holding body.

  • the second channel ends in a pressure chamber or in an outlet opening of the injection nozzle.
  • a sealant such as a sealing washer
  • the sealant on the Junction between the channels should be designed so that it is very can withstand large loads. For this reason, the known injection valves on the holding body and the nozzle body trained sealing surfaces on which the sealant is present, and the sealant itself with very high manufacturing accuracy and high surface quality. In addition, that sealing means arranged between the holding body and the nozzle body be compressed with such a large pre-tensioning force that the connection point between the two channels despite the high pressures does not leak.
  • the protruding into the channel Socket through the high acting inside the fuel supply Pressure is pressed against the inner wall of the channel and nestles against it Surface, creating a leak-free seal at the connection point between the channels.
  • both in the manufacture of the channel and in the manufacture of the Socket to the manufacturing accuracy and surface finish lower Requirements than with conventional injection valves, because of the high pressure that clings to the inner wall of the channel Jack any unevenness or dimensional deviations compensates.
  • the assembly of the injection valve is facilitated because the Jack also serves as a centering aid that the exact to each other Aligning the holding body and the nozzle body and that to each other Aligning the channels simplified.
  • the bushing is a section smaller Has outer diameter.
  • This design of the socket is achieved that the bushing in the weakened section smaller Diameter is expanded more than that by the high pressure not weakened sections of the jack, and the jack still better clings to the inner wall of the channel, while at the same time convex outwards. Due to the convex deformation of the Transition between the section of smaller diameter and the neighboring, non-weakened section of the socket linearly to the Inner wall of the channel, which creates a particularly good sealing effect is achieved.
  • the section of smaller diameter is preferred arranged in the area of the connection point between the channels, in order to achieve the highest possible sealing effect at the connection point.
  • the socket has a secure hold in the fuel supply, it can be pressed into the channels, so that between the socket and a press fit is formed on the inner wall of the respective channel.
  • the bushing can be made in one piece with the holding body or the nozzle body be trained.
  • the socket then serves as a tubular extension of the first and second channel after the assembly of the injection valve in the second channel of the nozzle body or the first channel of the holding body protrudes.
  • the injector there is the advantage that only a few when assembling the injection valve Components are to be assembled.
  • At least one of the channels on its other channel-facing end a section with a larger inner diameter has, in which the socket received or pressed is.
  • the socket formed as a separate component as in the first of the two exemplary embodiments described above, the Support the socket on the shoulder formed in the channel, which on the one hand migration of the bushing in the fuel supply is effectively prevented on the other hand, the socket through the paragraph in a predetermined Position in the fuel supply is held.
  • the fuel supply can be designed as a simple channel that runs through the holding body and the nozzle body.
  • the nozzle needle is in the longitudinal direction the needle guide between a rest position in which it is at least a spray hole connected to the second channel in the nozzle body closes, and a release position in which it can move the spray hole at least partially releases.
  • the fuel in this embodiment along the nozzle needle through the channels that serve as a needle guide promoted and trained at the end of the second channel Spray hole expelled.
  • a nozzle needle that extends over its length in the cross-sectional shape changing the dimensions. So has the nozzle needle preferably at least a section of larger diameter, which is the cross-sectional area through which the fuel flows and which of the Inner wall of the fuel supply and the outer surface of the nozzle needle is limited, downsized and acts as a throttle, reducing the flow resistance elevated.
  • the section of larger diameter is preferably at a distance from Needle tip formed on the nozzle needle so that the fuel flowed cross-sectional area of the fuel supply between the Needle tip and the larger diameter section of the nozzle needle is larger than the flow area of the fuel supply in the area of the larger diameter section of the nozzle needle. It is thereby achieved that the fuel in the longitudinal section of the Fuel supply in which the needle tip is located, a lower Flow velocity than in the length section of the fuel supply, in which the section of larger diameter of the nozzle needle located.
