Definitions

  • This invention relates to a fuel valve assembly arranged to be mounted in an opening in a chamber Wall.
  • the assembly is particularly suitable for mounting in a cylinder wall provided with a jacket forming a, space for the circulation of a cooling medium such as internal combustion engine cylinders.
  • An attachment member preferably in the form of a clamp isprovided for removably securing the valve within the bushing and particularly within the sleeve.
  • the bushing has means for engaging the attachment-member and securing the valve in its mounting in the chamber wall.
  • the bushing has a projecting edgeportion to which the attachment member or clamp is locked.
  • the clamp is preferably provided with a screw adapted to engage a recess in the valve housing and force the valve into proper position within the bushing,
  • the fuel valve and associated mounting and attaching elements are constructed and arranged whereby the fuel valve may be readily removed from itslmounting in the chamber wall Without interrupting the circulation'of cooling medium.
  • FIG. 1 is a sectional view of a valve assembly
  • Fig. 2 is a sectional view along the line 2-'2 of Fig. i; and Y.
  • Fig. 3 is a side view of the assembly shown in Fig. 1 from left to right.
  • the fuel valve assembly is mounted on the cylinder of an internal combustion engine and for which purpose the fuel valve assembly is especially suited.
  • FIG. 1 illustrates a fuel valve I having a nozzle or injector portion 2 containing the usual needle-valve operated by the needle-valve stem 3.
  • the inJector portion 2 has an axis coinciding with the axis ofthe needle-valve stem 3 which is preferably in the radial direction of the engine cylinder.
  • the needle-valve stem 3 is actuated by a valve spring 4 in the form of a bar mounted within a, housing 5.
  • the spring 4 and housing 5 are mounted crosswise to the axis of the valve.
  • the engine cylinder 6 (chamber wall) has a threaded opening 'I into which is screwed a valve mounting-member, preferably in the form of a bushing, 8.
  • the cylinder jacket 9 has an opening I ll concentric with the opening 1 and the bushing 8 is tightly fitted therein and the cylinder ycooling medium circulating in the space II is prevented from escaping by means of the packing materlallZ.
  • the bushing 8 has a central opening extending into the cylinder into which is fitted a jacket or sleeve I3 and an annular passageway I4 is formed in the bushing adjacent the sleeve.
  • Conduits I5 connect the space or passageway I4 ⁇ --with the cooling space II. By reason of this construction the cylinder cooling medium may be circulated from the space II through the conduits I5 and into the passageway I4.
  • the sleeve I3 i s constructed to accommodate the nozzle portion 2 of the valve and as illustrated in Fig. 1, that portion of the valve is cooled by means of its contact with the sleeve.
  • the bushing is preferably constructed with a. projecting edge-portion I6 adapted to effect engagement with a groove Il in the valve attachment-member I8.
  • 'I'he valve attachment-member is preferably constructed in the form of a clamp and the grooves il are arcuate and preferably concentric with the edge-portion I5 of the bushing.
  • a screw I9 is mounted in the central portion of the clamp having-a centering end portion 20 adapted to fit into a recess 2
  • theA valve and particularlysthe nozzle portion thereof, is mounted in the central opening of the bushing and the clamp is placed over the bushing with the grooves Il thereof in engagement with the projecting edge-portion I6.
  • the screw I9 is advanced until the centering portion 20 thereof is pressed into the recess 2I thereby centering and securing the valve in the bushing 8.
  • the fuel which is led in through the pipe 24, can be forced out through the passages 25, 26 of the fuel injection device.
  • the fuel valve 2 In the fuel valve 2,
  • a groove 21 is arranged, in which a key holds securely the outer part i of the fuel valve.
  • a groove 2l can be provided, in which a centering pin 2! for the spring bar is arranged. Any oil leaking out is led away through the pipe 30.
  • a further groove 3l can be provided in the cylinder and in it the key 31 fits.
  • a stop pin Il for the yoke I8 secures it.
  • a fuel valve assembly arranged to be mounted in an opening in a chamber wall having a cooling space between the wall. and a jacket which comprises a valve mounting-member fixed in the opening, said member having a passageway in communication with the cooling space for the circulation therein of a cooling medium.
  • a fuel valve mounted in the member, said fuel valve having an injector portion the axis of which extends through the opening in the wall, a spring for the fuel valve, a homing for the spring, said spring and housing being arranged crosswise to. the axis of the injector portion, and means for
