Description of the invention (2 Ding_〇 heart ah) ("limb full-wheel supercharger" hBr_, Bovene & △ Division Handbook, Baden / Switzerland, classification No. 0107, CH_T 1 22020). As far as this arrangement is concerned, the 3 basic lice can be branched directly from the compressor casing of the exhaust turbocharger, or can be supplied from an external source. However, the main purpose of this solution is @, Usually the focus is on the sealing and cooling function of the blocked air, preventing the accumulation only represents a positive effect. When the compressor air diverges as the blocked air, the efficiency of the compressor is reduced, and the efficiency of the internal combustion engine is reduced. , So there is a considerable reduction. When there is an external blocked air source, although this will not happen, but in the form of a compressed air container or a compressor and the necessary supply duct However, the corresponding additional complexity is caused. Disclosure of the Invention In an attempt to avoid all of these shortcomings, according to such an objective: "with minimal technical complexity and without loss of efficiency," an exhaust turbine is significantly reduced. Accumulation in the turbocharger's radial turbine that causes damage from the exhaust gas from the internal combustion engine. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) According to the present invention, This target is achieved by arranging at least one through-hole in the upstream area of the partition wall, and the through-hole will connect the airflow pipe to the gap through the hollow space. With the first pressure P The-shunt diverges from the mainstream of the working medium (exhaust gas of the internal combustion engine) of the radial turbine, which is the one that enters the air duct. The shunt is introduced to the part made between the partition wall and the turbine rotor. In the gap, and then release into the area of one of the air ducts with a second pressure p2 This paper size applies to China Standard (CNS) A4 (210 X 297 mm) 476839 A7 B7 5. In the description of the invention (3), 'the pressure Pl is greater than the pressure p2.

This bypass flow prevents the main ,,,,, and from the exhaust gas: Zhiling penetrates into the gap between the turbine rotor and the partition wall. In the k ^ way, the damaging product in the exhaust turbocharger radial turbine > several 'can be prevented by using a substance that is always on-site, without having to reduce the efficiency. ^ The at least one through-hole channel has a centerline which is relative to the centerline of the turbine— " *%% 念, / TL 田 ,, A ,,,. The sigh angle Φ is set to be opposite to the direction of the flow of the king, where φ 疋 is between 0 and 45 • ^. Because the set angle φ is within the prescribed range, the probability of the particle penetrating into the gap through the through-hole becomes smaller. The advantage of the oracle is that an orifice entrance is provided for the at least one through-hole, and the entrance of the orifice is made in the radial flow area of the surface of the partition wall as the boundary of the air duct, and is arranged in the gap. Upstream. By means of this device, the through-hole can be arranged upstream of the turbine rotor as far as possible, and the result is that there is a relatively large area between the area where the divergence diverges in the air duct guide and the area where the divergence enters the eunuch again. Available pressure difference. And, a direct, and thus relatively simple, connection between the airflow duct and the hollow space adjacent to the partition wall may be achieved. It is particularly useful that the entrance of the orifice is at a distance from the surface that is the boundary of the air duct, and the paper size of the surface and the entrance of the orifice is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out this page) I nnn I OJa n —annnn Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 476839 A7 B7 Printed by the Consumer ’s Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (4 rooms, making a slope-shaped cut ^ ^ ^ ^ with less soil approximately toward the mainstream of the working medium. In this way, the inlet σ u,, entrance is relative to the boundary of the air flow pipe The surface, indentation setting, so that reading Ji, $, intuition hole are located near the light supply flow of the working medium. With this setting, it is possible for the mass' I * following the flow in the heart gas to penetrate into the m channel. The probability is significantly reduced. In addition, the incision is arranged at a setting angle with respect to the mainstream direction of the working medium ^; the setting angle is set to be within an angle with the mainstream direction ± ΗΓ㈣circle, it is possible. In this way, the best supply stream of the split of the working medium used to keep the gap clean can enter the through-hole. The cutout must have an inlet cut surface and an outlet for the exhaust gas. Cut surface, and the through passage is useful in the area of the entrance cut. In addition, the exit cut has a flatter configuration than the entrance cut. The arrangement and configuration of the cut through can also reduce The probability of penetration of particles following the flow. The particles following the exhaust gas flow have a larger mass, and their inertia is greater than the inertia of the exhaust gas itself. Although these particles will be affected by the divergent shunts, they will deflect In the direction straight through the tunnel, however, due to the inertial relationship of Μ and 马, the particles cannot fall into these orifices. On the contrary, the far isotopes are turned in the direction of the exit and cut plane, and they are at the exit cut plane. It can only be difficult to accumulate, due to the flat configuration of the exit cut surface. Most of these particles are brought out of the incision again and merge with the mainstream. The tangent plane and the exit tangent plane form a common edge in the cut, and a hypothetical parallel line of the turbine centerline extends through the common edge. Between the entry tangent plane and the parallel line, an entrance angle is formed, and the Paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 public love) (Please read the precautions on the back before filling this page) UV4 ^^ · n ί Βϋ —ϋ an mi m ^!

Description of the invention (5) The exit angle of all mouths is formed between the exit cut plane and the parallel line %, The entrance angle y5 is between 0 ° and 45 ° and the exit angle% is at 45 °. And 9 〇. between. The main advantage is that an entrance angle can be selected, which can make the through-hole tunnel retract as much as possible, so the best protection can be obtained to avoid the mainstream passing nearby. On the contrary, the exit angle should be selected as flat as possible, so that the amount of the particle that can gather downstream of the through-hole is as small as possible. The selection of the different angle ranges, so that the cutout can be adjusted correspondingly to the application conditions set by the internal combustion engine and the exhaust turbocharger. Finally, an angle Θ, whose (M is between 45 ° and 13 5.), is best made between the entrance cut surface and the exit cut surface of the far incision. In this regard, an opening angle d of 90. In terms of manufacturing technology, it is relatively easy to implement. However, for a flow relationship, an opening angle of 0 ′ to 290 ° has better orientation than an opening angle of 0 ′ to 45 °.

The compressed air in the compressor is pressurized by the internal combustion engine with rice, that is, its power is increased. Lubricating oil 2 2 is supplied through a lubricating oil pipe 15 to lubricate the sliding bearing 8 of the exhaust turbocharger. Upstream of the nozzle ring 12, a shunt 24 having a first pressure P1 diverges from the main stream 23 of the working medium J 1 of the radial turbine 1, which goes into the air duct 10. This shunt The series 24 passes through the hollow compartment 20 and is introduced into the gap 19 formed between the partition wall 18 and the turbine rotor 7. It is also released in a region adjacent to the gap 19 in the airflow duct 10. A region has The second pressure P2 is less than the force pi present in the upstream region of the air duct 10.

The scope of the invention description (9). Because it is arranged in the area of the inlet cut surface 29, the orifice inlet 26 of the through-hole 21 is located near the flow path of the main flow 23 of the working medium 1 1 of the radial turbine 1. As a result, the through-hole 21 is hardly affected by the particles carried by the working medium 11 so that, in addition to the shunt 24, a relatively small number of particles can enter the gap 10. Because of the special configuration of the cutout 28, that is, because of the slope shape plus the beating edge 31, the particles in the main stream 23 of the working medium 11 are difficult to accumulate in this area, so that the orifice The entrances 2 and 6 can be kept free in and out at all times. It is thus possible to ensure a by-pass flow of a desired working medium 11 during a relatively long operating life of the radial turbine 1 of the exhaust swirler. This notch 2 8 is feasible by combining various inlet angles / 5 and outlet angle% for the desired flow conditions. As already explained in FIGS. 1 and 2, each of the through holes 21 has a center line 91, which extends parallel to the turbine center line 9. This centerline 9 'may, of course, have a value different from 0 for the turbine centerline 90. Set angle φ. In Fig. 3, it shows a single straight through-hole 21, which is an enlarged view related to Figs. I and 2, and the possible setting angle? Of the center line 9 'is at 0. And 45. In any case, it is opposite to the main direction 27, as shown by the dotted line. It is also shown that the through-hole 21 is likely to be at an extreme position. In the second specific example, twelve through-holes 21 are arranged on the partition wall 18-, and all are arranged around the outer peripheral edge thereof. Fig. 4 shows this method. A two-dimensional representative diagram is selected to emphasize the layout and configuration of the through-hole 2 i.

Description of the invention (10 ° As far as Ting Wan is concerned, the number of through-holes 21 used depends on the total cross-sectional area necessary for the through-holes 21 and depends on the purpose of blocking the mainstream 23 Depending on the mass flow of the shunt 24 necessary to penetrate into the gap 19, a larger number of directly encountered holes 迢 21 are, in principle, more suitable for individual through-holes 21 with larger diameters. Because the partition wall 18 has a different number and / Or through passages 21 with different overall cross-sections can be used. The radial turbine can be easily adapted to different operating situations by appropriately changing the partition wall 18 (for example, when using different fuels). ) According to a third specific example, the divergence of the shunt 24 from the working medium 11 main stream 23 of the radial turbine 1 has occurred within the turbine intake pipe 3. To this end, a duct 34 leads into the turbine The air inlet pipe 3 is fixed to the latter, and the duct 34 is connected to an associated hole 35 in the bearing housing 13. The hole 35 passes into the hollow space 20 in a manner similar to the through-hole 21 ( Figure 4). Where the catheter 34 acts, the The wheel inlet pipe 3 can be equipped with a device to avoid the penetration of particles: this item is similar to the device installed in the previous specific example.
