Abstract
The utility model provides a turbocharger compressor volute with a conical wind guide opening. The turbocharger compressor volute comprises a turbocharger compressor volute body, wherein the conical wind guide opening, which is casted with the volute body to form a whole, is formed at an air inlet of the turbocharger compressor volute body; and a flow guide cavity is formed between the conical wind guide opening and an air inlet of a flow passage in the volute body. In the turbocharger compressor volute provided by the utility model, the wind guide opening and the volute body are casted into a whole, and parts like wind guide rings and retaining rings of the wind guide ring are not needed, so that little material is consumed, the assembly procedures are simultaneously reduced, the production efficiency is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to the internal combustion engine turbocharger technical field, particularly a kind of turbosupercharger air pressure mechanism of qi spiral case.
Background technique
At present, in order to make the turbosupercharger noise reduction and to widen flow, usually the technological means that adopts is air-ducting ring, air-ducting ring back-up ring to be installed and to set up a secondary air inlet groove at the suction port of turbocharger air compressor spiral case runner at the suction port end of turbocharger air compressor spiral case, reaches the turbosupercharger noise reduction and widens the purpose of flow by above-mentioned design.Its structure is as described in the accompanying drawing 1, it comprises turbocharger air compressor spiral case body 1, set up a secondary air inlet groove 1-2 at the suction port of turbocharger air compressor spiral case body 1 runner, suction port 1 inwall at turbocharger air compressor spiral case body 1 is provided with a step annular groove 1-3 that air-ducting ring 3 and air-ducting ring back-up ring 2 are installed, air-ducting ring 3 and air-ducting ring back-up ring 2 are installed in step annular groove 1-3, air-ducting ring back-up ring 2 is pressed on the air-ducting ring 3, fixes air-ducting ring 3 by air-ducting ring back-up ring 2.Though at the turbocharger air compressor spiral case effect that air-ducting ring can play noise reduction and widen flow is installed, has the following disadvantages: 1, increase number of spare parts; 2, increase the machining preface; 3, increase assembly process.Will increase cost of production like this, reduce manufacturing efficiency.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of novel turbocharger air compressor spiral case is provided, it be will existing turbocharger air compressor spiral case former suction port be designed to a taper air guide hole and a diversion cavity.
The technical solution of the utility model is: a kind of turbocharger air compressor spiral case with the taper air guide hole, it comprises turbocharger air compressor spiral case body, suction port at turbocharger air compressor spiral case body is provided with one and spiral case body cast solid taper air guide hole, is provided with a diversion cavity between the runner suction port in taper air guide hole and spiral case.
After the air that enters from turbocharger air compressor spiral case taper air guide hole entered diversion cavity, runner suction port in the turbocharger air compressor spiral case and secondary air inlet groove entered the runner in the spiral case again, realized noise reduction and widened the purpose of flow.
The utility model compared with prior art has following characteristics:
The turbocharger air compressor spiral case that the utility model provides does not need to increase air-ducting ring, air-ducting ring back-up ring part with air guide hole and spiral case body cast solid, and consumptive material is few, reduces assembly process simultaneously, has improved manufacturing efficiency, has reduced cost of production.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Accompanying drawing 1 is the structural representation of existing turbocharger air compressor spiral case;
Accompanying drawing 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2: a kind of turbocharger air compressor spiral case with the taper air guide hole, it comprises turbocharger air compressor spiral case body 4, suction port at turbocharger air compressor spiral case body 4 is provided with one and spiral case body 4 cast solid taper air guide hole 4-2, is provided with a diversion cavity 4-1 between the runner suction port in taper air guide hole 4-2 and spiral case body 4.
Claims (1)
1. turbocharger air compressor spiral case with the taper air guide hole, it comprises turbocharger air compressor spiral case body, it is characterized in that: the suction port at turbocharger air compressor spiral case body is provided with one and spiral case body cast solid taper air guide hole, is provided with a diversion cavity between taper air guide hole and the intrinsic runner suction port of spiral case.
