PURPOSE: To facilitate assembly by a method wherein when a unit casing, a feed pump casing, and a fixed plate are intercoupled through a suction conduit and a discharge conduit, a support pipe is arranged to extend through the casings, and fastened by a screw.
CONSTITUTION: A unit casing 3 is coupled to a feed pump casing 5 coupled to a fixed plate 4, and the feed pump casing 5 is doubly supported at the fixed plate 4 by support pipes 1a and 1b arranged between the unit casing 3. The support pipes 1a and 1b are extended in the through holes 13a and 13b of the casing 5 and fastened by a screw 2. The central range of the support pipe 1a is surrounded by a middle large damping sleeve 8, the two end parts of the support pipe 1b are surrounded with the buffer sleeve 8 with a flange 8a. A partition chamber 14 between the casings 3 and 5 is crosslinked by a coupling small pipe 9. The through-hole 13c on the same axis therewith is sealed through fit-in of a pin 6.
