Abstract
The utility model discloses an oil return guiding device of an engine oil filter. The oil return guiding device is structurally characterized in that one end of a guide pipe is sealed, and the side wall, close to the sealed end, of the guide pipe is provided with a circular hole; the other end of the guide pipe is provided with a lug boss, a sealing pad is arranged on the inner side of the lug boss, and the lug boss of the guide pipe is fixed with the oil inlet end of the engine oil filter; a circular bead matched with a machine body of the engine oil filter is machined on a position, corresponding to the lug boss of the guide pipe, of the machine body of the engine oil filter, and the sealed end of the guide pipe is in interference fit with a machine body of an engine; the lug boss of the guide pipe is in interference fit with the circular bead of the engine oil filter so as to ensure mounting stability and firmness. As lubricating oil has a certain pressure, the sealing pad is additionally arranged between the machine body of the engine and the engine oil filter. According to the oil return guiding device, the guide pipe which is additionally arranged between an oil return hole of the machine body of the engine and the engine oil filter can be used for effectively guiding engine oil to flow back to an oil pan in a fixed direction so as to prevent dirty oil (containing impurities) from impacting and sputtering a crankshaft.
Description
Technical field
The utility model belongs to gas engine part, is specifically related to a kind of guiding device of diesel engine engine oil filter oil return.
Background technique
Can the lubricating oil system of any motor work, and is the key that can motor normally move safely.In the oil lubricating cooling system, machine oil will joined a little impurity of amalgamation through the multi-part cool cycles and after lubricating in oil, if these small granule foreigns enter into engine component, just will produce serious wearing and tearing to parts, the effect of oil filter is mainly to filter out these granule foreigns.In the cooling and circulatory system, machine oil is got back to oil sump through oil filter, on body, is provided with the passage (hole) of special oil return at machine oil.The spill port of design mostly is the parallel body inner chamber that passes at present, and because there is certain pressure in oil return, this kind structure easily causes the oil return splash to bent axle, causes drainback passage " short circuit ", is not easy the impurity in thorough filtering oil.The utility model proposes a kind of guiding device of oil filter oil return, can guide machine oil slave oil rectifier to flow back to oil sump, prevent the generation of drainback passage short circuit phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of oil filter oil return guiding device.
Below in conjunction with accompanying drawing, the technical solution of the utility model is explained.
Oil filter oil return guiding device, its technology division is: guide pipe one end sealing is provided with a circular hole at guide pipe near on the sidewall of closed end; The other end of guide pipe is provided with boss, and the boss inboard is provided with sealing gasket.The closed end of guide pipe is connected with the engine body interference fit, and the boss of guide pipe and the oil inlet end of oil filter are fixed.
Characteristics of the present utility model are, between engine body spill port and oil filter, install a guide pipe additional, just can effectively guide machine oil to flow back to oil sump with fixed-direction, prevent that (with impurity) dirty oil from impacting splash to bent axle.
The accompanying drawing explanation
Fig. 1 is the utility model guide pipe structural drawing.
Fig. 2 is theory structure diagrammatic sectional view of the present utility model.
Fig. 3 is the utility model embodiment mounting structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, structure of the present utility model is further described.
Oil filter oil return guiding device, its structure is: an end sealing of guide pipe 1 is provided with a circular hole at guide pipe near on the sidewall of closed end; The other end of guide pipe is provided with boss (as Fig. 1), and the boss inboard is provided with sealing gasket 3, and the closed end of guide pipe is connected with engine body 2 interference fit, and the oil inlet end of the boss of guide pipe and oil filter 4 is fixed (as Fig. 2 Fig. 3).
Guide pipe boss end passes sealing gasket, with the filler opening of oil filter, fixes.Lubricating oil enters guide pipe from the oil filter drainback passage, and the circular hole aperture on the guide pipe sidewall is (towards oil sump) down, with the machine oil of certain pressure, in guide pipe, turns by the circular port on sidewall and directly is back in oil sump.
Guide pipe opening one end is provided with circular boss, on position corresponding to oil filter body, is processed with the shoulder that coordinates with it.The closed end of guide pipe and engine body interference fit; The shoulder interference fit of guide pipe boss and oil filter, stablize firmly to guarantee to install.Because be provided with guide pipe, so need between engine body and oil filter, install sealing gasket additional, by bolt, get final product oil filter and body are fixing.The machine oil that the slave oil rectifier flows back to is got back in oil sump according to the route of design.
