Definitions
- the present invention relates to a sump lubrication oil suction duct of an internal-combustion engine, provided with forced lubrication.
- This arrangement of the suction duct has some inconveniences, for example the movement limitations of the pump provided with said suction means during assembly and during maintenance when sump removal is needed. A further inconvenience is due to the breakaway incidents of the duct with suction means due to vibrations or to faulty fixing during assembly.
- the distance of the suction means from the sump bottom is determined by a plurality of components with wide tolerances in the assembly dimensions.
- the oject of the present invention is to realise an oil suction duct that overcomes said inconveniences.
- numeral 2 indicates an oil sump of an internal combustion engine (not shown), connected by blocking means 4 to said engine block.
- Said sump 2 obtained through sand casting, comprises on its side wall, an internal projection 6 wherein an oil duct 8 is obtained.
- Said duct defining the first portion of the complete oil suction duct, has an L shaped axial section, and has a first end outlet near the sump upper part, in correspondence with the oil pump suction opening placed on the lower part of the engine block (not shown), so as to be therein connected during the sump assembly to the engine block.
- the sealing of said connection is secured by a gasket 9 positioned around duct 8 outlet.
- the other end of the first portion of duct 8 forms substantially a 90° angle with the first end, and has an outlet inside the sump, underneath the upper edge resting on the engine block lower portion.
- the second portion 14 of said suction duct is connected thereto by means of a flange 10 held by means of gripping bolts 12, and said second portion ends with suction means 16 attached to the sump 2 bottom 18 through a nut 20 screwed on a projection 22.
- suction duct for the engine oil which, besides said advantages, enhances the engine assembly since it reduces and simplifies the necessary operations. Further the distance between the suction means and the sump bottom is exclusively determined by the coupling of the suction means 16 with projection 22.
- the invention allows a better handling of the oil pumps and a more rational positioning of the duct hardly influencing the suction system total weight.
