1,170,721. Pipe joints. DAIMLER-BENZ A.G. 4 Jan., 1968 [7 Jan., 1967], No. 672/68. Heading F2G. In an injector pump 1 for internal combustion engines comprising a spring housing 4 secured in the pump body, valve 3, and pump plunger and cylinder 2, the spring housing is provided with a bore 12 extending at right angles to the plunger and cylinder axis and terminating in a conical seating 11 against which the coned end 13 of an injection pipe 14 is directly clamped. As shown, the pipe end is clamped against the conical seating by a nut 18 threadedly engaged in a bored block 15 receiving the housing and the housing is secured in the pump body by a sleeve 7 which is screwed into the pump body and engages an annular shoulder 6 at the end of the housing. In a modification, Fig. 2 (not shown), the pipe end is clamped against the conical seating by a nut threaded directly on to a lateral integral extension of the housing and the housing is in screw engagement with the sleeve, the thread pitch of the housing/sleeve screw engagement being less than the thread pitch of the sleeve/pump body screw engagement. |
