A pressure-tight connection joint between a solenoid valve and a fuel injection pump, the valve casing having casings in contact with each other at the sealing surfaces in which there are connection openings that communicate with each other, and a fuel injection pump. or a clamping flange fixed to the pump casing is provided, the clamping flange being connected to the valve casing or the pump casing via a reduced diameter clamping neck disposed on the back side of the clamping flange and the front side of the clamping flange. A hollow cylindrical tightening nut is provided which has a sealing surface on the side and engages with the tightening flange from the outside, and the tightening nut projects in the axial direction beyond the front side of the tightening flange and extends into the projecting range. A tightening flange 33 provided on a tightening nut 34 in a type that has a screw thread to be screwed into a pump casing or a valve casing and engages with the back side of the tightening flange to tighten and fix the tightening flange. The inner diameter of the through opening 48 is large enough for the tightening nut 34 to pass through the through opening 4.
8 and an annular recess 37 in the inner wall, which is directly adjacent to said recess 37 toward said thread 36, and has a machining recess 42 having a greater radial depth than said recess 37; The tightening nut 34 is fitted into the recess 37 with respect to the tightening flange 33.
It engages via a snap spring 39 which is located within and has only a minimum separation gap 50 in the abutment area, which snap spring 39 has an inner diameter smaller than the outer diameter of the tightening flange 33 and the through hole. It has a larger outer diameter than the inner diameter of the opening 48, and the back surface of the tightening flange 33 and the recess 37,
The snap spring 39 is supported by the radial side face opposite to the machined recess 42 , and is twisted in the area of the separation gap 50 using a mounting tool 80 in order to install the snap spring 39 on the tightening nut 34 . , is pushed into the through opening 48 of the tightening nut 34 in the axial direction until it reaches the working recess 42, and when the tightening flange 33 is passed through the through opening 48, it elastically expands into the working recess 42. is,
A pressure-tight connection joint, characterized in that the clamping flange 33 is then elastically returned after passing through the machining recess 42 and brought into contact with the clamping neck 35. 2. The axial length of the machined recess 42 is approximately the same as the axial height h of the tightening flange 33, and the radial depth of the machined recess 42 is approximately the same as the radial width dimension of the snap spring 39. The connection joint according to claim 1. 3. The cross section 40 of the snap spring 39 is a circular surface, and the side surface 38 of the recess 37 has an arcuate shape adapted to the cross section 40, and has a radial depth at least corresponding to the radius of the cross section 40. The connection joint according to claim 1 or 2, comprising: 4. In the transition region between the tensioning neck 35 and the rear side of the tensioning flange 33, an annular arc-shaped recess 41 is provided which forms a form-locking crimping surface for the snap spring 39. connection flange. 5. Connection flange according to one of claims 1 to 4, characterized in that the clamping neck (35) has a free length at least equal to the axial height h of the clamping flange (33). 6. When the tightening flange 33 is passed through, the snap ring 39 disposed in the recessed portion 41 is expanded by a second installation tool 71, and the installation tool 71 is installed just before the tightening flange 33. 1 . The locking nut 34 is moved through the through opening 48 of the tightening nut 34 by being led by the locking nut 34 .
The connection joint according to any one of items 5 to 5.
