Definitions

  • the invention relates to a fuel guide in the cylinder housing an internal combustion engine with the in the preamble of the claim 1 specified characteristics.
  • such a fuel guide is in Known cylinder housing of a multi-cylinder internal combustion engine, which from a continuous longitudinal channel as fuel feed and from feed channels branching off from the longitudinal channel consists.
  • Each feed channel opens into one in the cylinder housing arranged receiving hole, in which the corresponding Plug-in pump assigned to cylinder is inserted.
  • the plug-in pump is in Height of the mouth with one connected to the feed channel Provide ring groove.
  • the invention has for its object a cylinder housing and simple fuel feed connecting each plug-in pump to create through the effortless position fixation of the plug-in pump can be reached in the mounting hole in the cylinder housing.
  • the fuel guide should be used especially for plug-in pumps Solenoid valve control may be suitable.
  • the task is with a generic fuel management by the specified in the characterizing part of claim 1 Features resolved.
  • sleeve-resistant sliding block 11a and a slot-like sliding block guide 10a in the roller tappet 10 form an anti-loss device, so that when the plug-in pump 5 is removed from the receiving bore 4 falling out of the roller tappet 12 prevented from the sleeve 11 becomes.
  • the lower area of the pump housing 6 is designed in stages, the larger diameter portion 6a two lying one above the other Sealing rings 13, 14 and in the overhead Bore section 4a is mounted and the diameter smaller part 6b firmly connected to the upper part of the sleeve 11 is.
  • a pressure shoulder 15 formed by the step on the pump housing 6 lies on the end face of the sleeve 6.
  • Pump housing part 6 contains a solenoid valve 16 for control the flow paths in the fuel lines.
  • the longitudinal axis a runs transverse to the axis c of the camshaft 9, the imaginary extension of the longitudinal axis a a distance x to the camshaft axis c, such that the extended Longitudinal axis a of the plug-in pump 5 behind the camshaft axis c lies - starting from the cylinder 3 in the direction of the camshaft 9 considered.
  • the direction of rotation of the camshaft 9 is opposite to that Clockwise, that means the roller 17 of the roller tappet 10 acts as a follower and thus a stable alignment in their storage and running.
  • the lateral housing projection 20 has a fuel line 22 with a parallel to the longitudinal axis a of the plug-in pump 5 and stepped line section 23, the arranged coaxially to a feed channel 24 in the cylinder housing 1 is.
  • the feed channel 4 branches off from a longitudinal channel 25 which in the cylinder housing 1 next to the plug-in pumps 5 as a continuous Fuel supply extends.
  • a sleeve 26 In the line section 23 is a sleeve 26 to one through the stage formed pressure shoulder 27 inserted and there fixed.
  • the sleeve 26 sticks with her from the line section 22 protruding part in the feed channel 24 of the cylinder housing 1 and forms a position lock for the plug-in pump 5 in the Location hole 4.
  • the plug-in pump 5 is on the cylinder housing 1 attached by fastening screws 28.
  • the opposite of the bearing surface 21 on the cylinder housing 1 Contact surface 29 on the housing projection 20 is the sleeve 26 surrounding recess 30 in which a sealing ring 31st lies, the captive pushed under tension on the sleeve 26 is.
  • the line connection in this special way between the cylinder housing 1 and the plug-in pump Sleeve 26 protects the sealing ring 31 against the adjacent very high system pressure.
