Abstract:
PCT No. PCT/DE97/01996 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Sep. 9, 1997 PCT Pub. No. WO98/27335 PCT Pub. Date Jun. 25, 1998A process for leak testing in fuel injection pumps that have a pump housing that can be plugged into a motor housing, in which an outlet of the fuel injection pump, which feeds into an annular chamber that is divided by sealing rings and is normally discharged by way of a line, is closed with a material in order to carry out a leak test. The material is plastically deformable and dissolves with the heating of the fuel, and due to its plasticity, produces a sealed closure of the annular chamber in relation to the interior of the fuel injection pump so that the annular chamber can be loaded with a testing pressure via the line.
