BRACKET OF HIGH-PRESSURE PUMP FOR INTERNAL COMBUSTION ENGINES

摘要

On the bracket of the high-pressure motor pump with internal combustion a nest (5) for the receipt of complementary parts is designed in such a way that the recess (50) - looking in the direction of depth - runs perpendicularly regarding the wall (20) surface (1) of the bracket, while in the recess (50) of the nest (5) there is a positioning rib (54) directly located next to the aforementioned opening (53) between the walls (51, 52), anticipated for creating a bedding for the positioning bushing during installation. Further, there are two additional ribs (26, 27) anticipated on the circumference of the wall where the reinforcement rib (25) is running, which are running approximately perpendicularly one against the other, in fact the first rib (26) runs in the tangential direction regarding the specified central opening (200) in the wall (20) and approximately in the vertical direction, while the remaining rib (27) is located beneath the specified opening (200) and at a certain distance from the latter while running at least approximately horizontal. At the same time differently from the mechanically processed lower sides (32, 42) the upper surfaces (31, 41) of the fixing ears (3, 4) are mechanically not processed. Such a bracket (1) can be manufactured with the help of simple and low-cost casting tools or moulding in the technological process of classical pressure casting of aluminium or any corresponding aluminium alloy, while its static firmness is substantially enhanced.
