Owing in the main road of lubricant oil, be provided with one-way valve, certain pressure loss appears in delivery line, like this transport pipe than doing of real needs more greatly, the perhaps bearing of exhaust-gas turbocharger supplying lubricating oil best.
For this reason, this regulating element that is arranged in the lubricant oil main road can bring the potential danger that hinders transferring oil when possible fault appears in the function of these regulating elements.
The present invention attempts the shortcoming of avoiding all.Task of the present invention is to propose lubricant oil in a kind of bearing housing that is arranged on exhaust gas turbine and increases device and carries the fuel reserve tank that has improved.
According to the present invention is this task of finishing like this, that is, and and in device, except throttle orifice is provided with a same one-way valve that feeds fuel reserve tank in outlet pipe according to claim 1 preamble.
When the lubricant oil supply fault that carries out through delivery line, the oil column that flows back to delivery line is via being arranged on the throttle orifice in the outlet pipe and being arranged in the one-way valve of outlet pipe equally and supplying gas by the present invention.Cancelled the necessity that one-way valve promptly is set in the delivery line like this in main road.Based on this, when supplying, lubricant oil causes the less pressure loss.At last, improved the conveying of lubricant oil thus, can realize lubricated oil supplying reliable and inexpensively by the one-way valve of cancellation in delivery line.
The topmost part that one-way valve is arranged on outlet pipe is especially favourable.Can in single part, realize the simple combination of throttle orifice and one-way valve like this, bring lower cost of production thus.
At last, the lubricating oil tank of the internal-combustion engine that will link to each other with exhaust-gas turbocharger is advantageous as the lubricating oil bath that the outside at exhaust-gas turbocharger is provided with.
In the accompanying drawings, by means of an exhaust-gas turbocharger that links to each other with internal-combustion engine one embodiment of the present of invention have been described.Wherein:
Fig. 1 schematically illustrates the exhaust-gas turbocharger that links to each other with internal-combustion engine in the prior art;
Fig. 2 represents the just exhaust-gas turbocharger of the Fig. 1 behind internal combustion engine start;
Fig. 3 is the diagrammatic sketch according to Fig. 2, yet is normally in service at exhaust-gas turbocharger;
Fig. 4 is the diagrammatic sketch according to Fig. 2, yet is in service at the standby oil of exhaust-gas turbocharger.
Only show among the figure for understanding the important element of the present invention, and for example compressor side and the turbo-side of exhaust-gas turbocharger are not shown.The flow direction of working medium is represented with arrow.
Exhaust-gas turbocharger 1 mainly is made of a not shown compressor and a same unshowned turbine that is supported by a public axle 2.They are separately positioned in the housing.Axis 3 is by axle 2 horizontal-extendings.The bearing of axle 2 is so-called inner bearings, and promptly axle 2 is supported on the corresponding bearing 4 of scope between compressor and the turbine.The position of the axle 2 that is provided with between compressor and turbine, supported by bearing 4 is surrounded by bearing housing 5, and this bearing housing 5 not only links to each other with compressor housing but also with turbine shroud.
Fig. 1 schematically illustrates the exhaust gas turbine that links to each other with internal-combustion engine 6 in the prior art increases device L wherein, and the ratio of the amplification of these two machines does not conform to the actual conditions.Top in the inside of bearing housing 5 is provided with a fuel reserve tank 7.Fuel reserve tank 7 links to each other with the lubricating oil bath that is designed to oil groove 10 of internal-combustion engine with a delivery line 9 that links to each other with this transport pipe via transport pipe 8.Wherein, transport pipe 8 links to each other via flange 11 with delivery line 9, links to each other via case lid 12 with fuel reserve tank 7.A transfer pump 13 is set in delivery line 9, a link 14 as one-way valve is set in transport pipe 8.Between bearing 4 and fuel reserve tank 7, constitute service duct 15.For this reason, at the foot of bearing housing 5, oil return line 16,16 ' is set respectively in the both sides of axle 2.Yet, have only oil return line 16 to link to each other with the lubricating oil bath 10 of internal-combustion engine 6 via return line 17.Second oil return line 16 ' is with covering 18 sealings.An outlet pipe 19 is set in bearing housing 5, and the latter has a throttle orifice 20 at the end that it inserts fuel reserve tank 7, and the other end feeds the free chamber 21 of bearing housing 5.
When internal-combustion engine 6 operations, hot waste gas arrives turbine and drives turbine.Turbine is used to drive through the coupled compressor of axle 2.Compressed air arrives internal-combustion engine 6 and is used for supercharging, the i.e. power of increasing combustion engine there via unshowned delivery pipe in compressor.In this process, axle 2 and whole rotor part reach very high peripheral velocity.In order farthest to reduce relevant friction, axle 2 is supplied with lubricant oil 22 all the time in this course.For this reason, lubricant oil 22 is transported to fuel reserve tank 7 by means of transfer pump 13 from the lubricating oil bath 10 of internal-combustion engine 6, and is transported to bearing 4 via service duct 15 therefrom, and wherein, fuel reserve tank 7 is arranged in main road, therefore, pressure is arranged all the time.Lubricant oil 22 then returns the lubricating oil bath 10 of internal-combustion engine 6 via oil return line 16 and oil circuit 17 from bearing 4.
When the lubricant oil supply of internal-combustion engine 6 was broken down, the pasta in the fuel reserve tank 7 descended.In this case, the free chamber of fuel reserve tank 7 charges into air via outlet pipe 19 and throttle orifice 20 from bearing housing 5, and transport pipe 8 guarantees that by means of link 14 lubricant oil 22 does not reflux.Therefore, the fuel feeding of the bearing portion of exhaust-gas turbocharger 1 can also guarantee a period of time, and the lubricant oil 22 in fuel reserve tank 7 uses up.During this period of time, exhaust-gas turbocharger 1 both can be shut down, also regular supply lubricant oil once more.But got rid of exhaust-gas turbocharger 1 because of lacking the accident of lubricant oil 22.
In one embodiment of the invention, in outlet pipe 19, a same one-way valve 23 (Fig. 2) that feeds fuel reserve tank 7 is set in the outside of throttle orifice 20.As above-mentioned prior art, lubricant oil 22 is transported to exhaust-gas turbocharger 1 by delivery pipe 9 and transport pipe 8 when internal combustion engine start, thereby is full of fuel reserve tank 7.Wherein, the bearing 4 of exhaust-gas turbocharger 1 is lubricated via service duct 15.The exhaust of fuel reserve tank 7 is to realize by means of the throttle orifice in bearing housing 5 free chambers 21 20.
Normally in service at internal-combustion engine and exhaust gas turbine 1, fuel reserve tank 7 has lubricant oil 22 to flow through, and therefore, bearing 4 is supplied with enough lubricant oil.Unnecessary lubricant oil 22 is drained via throttle orifice 20, returns the lubricating oil bath 10 (Fig. 3) of internal-combustion engine 6 then via oil return line 16 and oil circuit 17 with the lubricant oil 22 that flows through bearing 4.Because one-way valve 23 is closed in above-mentioned running state, the bypass amount of lubricant oil 22 does not improve.
Promptly in service, fuel reserve tank 7 is drained, and at this moment bearing 4 is continued supplying lubricating oil.Wherein, fuel reserve tank 7 charges into air (Fig. 4) with the volume that returns the oil column in the transport pipe 8 via throttle orifice 20 and one-way valve 23 from bearing housing 5.Therefore, at first stoped lubricant oil 22 to pass back into transport pipe 8, because transport pipe is connected on the topmost part of fuel reserve tank 7.Under the situation that continues assurance function, can save the link 14 that in described prior art, is arranged in the transport pipe 8 thus.
