Abstract
The invention discloses a small-displacement gasoline engine supercharger assembly. A decompression valve is integrated on a compressor. The small-displacement gasoline engine supercharger assembly comprises a supercharger decompression valve seat, a compressor inlet pipe, a compressor outlet pipe, a decompression valve inlet pipe, a decompression valve outlet pipe and the compressor, wherein all the parts are connected into a whole in a casting mode. According to the small-displacement gasoline engine supercharger assembly, the problem that integration of a small-displacement engine can not be achieved because a compressor casing is too small in the prior art is solved, a decompression valve inlet rubber tube or a decompression valve outlet rubber tube or clamps are not needed, installation processes and additional supercharger decompression valve installation points are reduced, thus, cost is reduced, and arrangement difficulty is reduced as well.
Description
Technical field
The present invention relates to a kind of exhaust-gas turbocharger.
Background technique
Along with people are more and more higher and environment is more and more paid attention to the requirement of engine consumption, on increasing motor, adopted turbosupercharger to reduce oil consumption and to improve discharge, in order to guarantee the normal work of turbosupercharger safety, therefore need to use pressurized machine recycle valve to carry out pressure release to the gas of gas compressor end when bringing to a halt and suddenly subtract throttle.The pressurized machine of present stage 0.8L and following small displacement engine is because compressor housings is too small, and Decompression valves all and be non-integrated form between pressurized machine, need to be with the connection of rubber pipeline, and Decompression valves also needs to find mounting points to be fixed, and has greatly increased layout difficulty and cost.
Summary of the invention
The object of the invention is to solve the problem of the increase of layout difficulty that small displacement engine pressurized machine Decompression valves and pressurized machine can not integratedly cause and cost, proposes a kind of small-displacement gasoline engine pressurized machine assembly.
Technological scheme of the present invention is as follows:
A small-displacement gasoline engine pressurized machine assembly, it comprises turbo machine, intermediate gas compressor and exhaust gas valve final controlling element, and turbo machine is connected with gas compressor by intermediate, and exhaust gas valve final controlling element two ends are connected with gas compressor with turbo machine respectively; It is characterized in that: at the shell integrally casting of gas compressor, be formed with Decompression valves valve seat, Decompression valves inlet pipe and Decompression valves and go out pipe, Decompression valves is arranged on Decompression valves valve seat, Decompression valves valve seat is outward that part is unsettled at the shell of gas compressor, Decompression valves inlet pipe is drawn from gas compressor inlet pipe, connect Decompression valves valve seat, Decompression valves goes out pipe and from gas compressor, goes out pipe and draw, and connects Decompression valves valve seat.
The design of this patent is in the situation that meeting intensity, to make Decompression valves valve seat part unsettled, then by go out direct introduction pipe on pipe at gas compressor, be connected on valve seat, pressurized machine Decompression valves can be integrated on pressurized machine, and the pressurized machine that has solved 0.8L and following small displacement engine is because compressor housings is compared with problem little and cannot integrated Decompression valves.
compared with prior art, tool has the following advantages in the present invention:
1) valve seat of Decompression valves directly designs on the pressure shell of pressurized machine assembly, and Decompression valves does not need to find everybody installation and Support Position;
2) suction tude of Decompression valves and steam outlet pipe all design on pressure shell, form an integral body with compressor casing, have saved Decompression valves suction tude and steam outlet pipe and clip, and have reduced assembly technology step.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, turbo machine, 2, intermediate 3, gas compressor, 4, gas compressor inlet pipe 5, exhaust gas valve final controlling element 6, Decompression valves 7, Decompression valves valve seat 8, Decompression valves go out pipe 9, Decompression valves inlet pipe 10, gas compressor and go out pipe
Embodiment
Referring to Fig. 1, pressurized machine assembly includes turbo machine 1, intermediate 2, gas compressor 3, exhaust gas valve final controlling element 5 and Decompression valves 6, and turbo machine 1 is connected with intermediate 2, then is connected with gas compressor 3, and exhaust gas valve final controlling element 5 two ends are connected with gas compressor 3 with turbo machine 1 respectively.Decompression valves 6 is arranged on Decompression valves valve seat 7, then Decompression valves inlet pipe 9 is drawn and is connected with Decompression valves valve seat 7 from gas compressor inlet pipe 4, Decompression valves inlet pipe goes out pipe 10 from gas compressor draws and is connected with Decompression valves valve seat 7, and Decompression valves valve seat 7 goes out pipe 10 with gas compressor again and is connected.Decompression valves valve seat 7 goes out pipe 10, Decompression valves inlet pipe 9 and Decompression valves with gas compressor inlet pipe 4, gas compressor and goes out pipe 8 by integral body of form of casting, Decompression valves valve seat 7 is outward that part is unsettled at the shell of gas compressor, make like this pressurized machine Decompression valves be integrated on gas compressor, reduce thus rubber pipe, clip, the extra mounting points of Decompression valves, and reduced assembly process.
