Abstract
The casing of the high-pressure pump consists of two integral segments. The first segment comprises a cylindrical borehole receiving the pump shaft 5 and its ball bearings 4. The second segment 1b comprises another borehole receiving a swash plate 9 rigidly affixed to the pump shaft 5, a cylindrical core 11 with parallel sides 11a, 11b and crossed by a plurality of open-end boreholes 12 receiving the pistons 13, a second cylindrical core 16 bearing check-valves 17, and a plug 19 resting against a shoulder 18 of the second core 16 in such manner as to keep the cores 11 and 16 compressed against each other and resting against a circular stop 7 in the second segment 1b of the pump casing 1. The inner boreholes of the two segments 1a and 1b are separated by a seal 2 and the parts located in the second segment 1b are in contact with the injection gasoline.
