Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Of the present utility model pair of boosting internal combustion engine turbosupercharger return line structure advantages of simple, by adopting a return tube to two pressurized machine oil returns, can effectively reduce oil return pipe of supercharger cost, reduce oil leakage fault rate and improve operational safety, characteristics of compact layout is attractive in appearance, easily applies.
Detailed description by way of example but unrestriced mode has illustrated the disclosure, should be understood that the realization that can be combined by independent realization or with other aspects in various aspect of the present disclosure below.This specification clearly enables those skilled in the art to manufacture and uses us to believe for new and non-obvious improvement, describe some embodiments, alternative, modification, alternative and system applies, comprised the current best mode that is considered to carry out the model utility principle of describing in this specification.In the time describing element or feature and/or embodiment, be intended to expression titled with " one " " one " " be somebody's turn to do " and " described " and there are one or more in element or feature.Term " comprises " that " comprising " and " having " is intended to is comprising property, and also has extra element or feature beyond being illustrated in those specifically described elements or feature.
As shown in Figures 1 to 6, the concrete structure of this pair of boosting internal combustion engine turbosupercharger return tube comprises: oil return manifold I 1, oil return manifold II 4 and take over the 5 oil return house stewards 6 that are connected with two oil return manifold oil outlet ends by trident, be that oil return manifold I 1, oil return manifold II 4 and oil return house steward 6 are connected with three interfaces of trident adapter 5 respectively, two pressurized machine return openings of two boosting internal combustion engines are connected with the filler opening I 2 of oil return manifold I 1 and the filler opening II 3 of oil return manifold II 4 respectively, and oil return house steward 6 return opening 7 is connected with the return opening on body or oil sump.While joining the internal combustion engine of two pressurized machines, the lubricant oil of two pressurized machines of flowing through flows to respectively oil return manifold I 1 and oil return manifold II 4 under Action of Gravity Field, take over 5 places at trident, two strands of lubricant oil pools one and flows to through oil return house steward 6 body or the oil sump of internal-combustion engine.By adopting a return tube to two pressurized machine oil returns, can effectively reduce oil return pipe of supercharger cost, reduce oil leakage fault rate and improve operational safety, characteristics of compact layout is attractive in appearance, easily applies.
The oil inlet end of oil return manifold I 1 and oil return manifold II 4 all has oil-feed flange 22, oil return manifold I 1 and oil return manifold II 4 are connected with the return opening of two pressurized machines of the internal-combustion engine of joining two pressurized machines by oil-feed flange 22, and the lubricant oil of two pressurized machines of flowing through flows to oil return manifold I 1 and oil return manifold II 4 by the filler opening I 2 of oil return manifold I 1 and the filler opening II 3 of oil return manifold II 4 respectively under Action of Gravity Field.The filler opening of oil return manifold I 1 and oil return manifold II 4, except can being connected with flange, can also be connected with pressurized machine return opening by swivel nut or other Placement herein.
The oil inlet end of oil return manifold I 1 and oil return manifold II 4 is laid with bellows 21, and oil-feed flange 22 is laid in the outer end of bellows 21.Because bellows 21 has certain flexibility, when installation, bellows 21 can be adjusted the position of oil-feed flange 22, has reduced installation difficulty.
Trident is taken over 5 and is had three interfaces, is connected respectively with oil return manifold I 1, oil return manifold II 4 and oil return house steward 6.The lubricant oil of two pressurized machines flows into respectively oil return manifold I 1 and oil return manifold II 4 under the effect of gravity, takes over 5 places and pools after one, then flow out from oil return house steward 6 return opening 7 at trident.
At oil return house steward 6 return opening 7 places with oil return flange 23, for connecting the spill port on the body of internal-combustion engine or on oil sump.Certainly also can connect by swivel nut or other Placement herein.Two oil return pipe of superchargers are simplified for one, reduced the quantity of special purpose parts, and then reduce manufacture cost, purchase cost and stock control cost, Assembly of the parts cost etc.A return tube just can supply two pressurized machine oil returns simultaneously, and on body or on oil sump, only with opening a return opening, sealing surface has reduced, and has therefore reduced oil leakage fault rate.And this kind of oil return pipe of supercharger characteristics of compact layout is attractive in appearance, easily applies.
