Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Fig. 1 and Fig. 2 are referred to, the embodiment of the present invention includes：
A kind of adjustable back-to-back bilateral-pressure impeller turbocharger, including：Body 1, the body 1 offer at least two and entered
Gas port, respectively normally opened air inlet 2 and can be opened and closed air inlet 3, and the inside of body 1 is provided with a pair of side pressure impeller 4, described normally opened
Air inlet 2 is respectively arranged on the both sides of the bilateral pressure impeller 4 with that can be opened and closed air inlet 3, and the bilateral is pressed in the output end of impeller 4
Provided with diffusion passage 5, connected by the diffusion passage 5 with vortex road 6, a side wall of the diffusion passage 5 is provided with removable
Dynamic formula diffusion adjustment disk 7, the diffusion adjustment disk 7 are connected with a control valve.
Described be opened and closed on air inlet 3 is equipped with opening and closing valve 8, and the opening and closing valve 8 is expanded by a linkage 9 and one
Pressure adjustment disk 7 connects.By controlled opening/closing valve 8, by linkage 9 diffusion adjustment disk 7 can be driven to move.
By the way that the air inflow being opened and closed to increase or reduce compressor of air inlet 3 can be opened and closed, to meet big flow scope
Engine calls.
As shown in figure 1, when opening and closing valve 8 is closed mode, diffusion adjustment disk 7 adjusts the channel width of diffusion passage 5
For minimum widith.
When engine speed is relatively low, in the case that distributive value is few, the air inflow needed for engine is few.Now it is opened and closed valve 8
Closing can be opened and closed air inlet 3, and air can only be entered by normally opened air inlet 2, lead in the presence of bilateral presses the left side blade of impeller 4
Cross diffusion passage 5 and enter vortex road 6.Now diffusion adjustment disk 7 causes the width of diffusion passage 5 in the presence of linkage 9
In minimum state to meet that current bilateral pressure impeller 4 only has the requirement under the blade operative condition of left side.
As shown in Fig. 2 when opening and closing valve 8 is open mode, diffusion adjustment disk 7 adjusts the channel width of diffusion passage 5
For Breadth Maximum.
When engine speed is high, distributive value is big, and the opening of valve 8 is opened and closed in the case that required air inflow is big can be opened and closed air inlet
3, enable air to while from normally opened air inlet 2 and can be opened and closed the air inlet of air inlet 3, and the left and right sides blade of bilateral pressure impeller 4
Play a role simultaneously, pass the gas through diffusion passage 5 and enter vortex road 6.The now diffusion adjustment disk in the presence of linkage 9
7 cause the width of diffusion passage 5 to be in maximum rating to meet the current bilateral pressure left and right sides blade of impeller 4 operative condition simultaneously
Under requirement.
In the case where booster is in same rotating speed, the air inflow of two air inlet air inlets simultaneously is an only inlet charge
When twice, the scope that whole compressor is provided to the air inflow of engine has obtained fairly effective extension.
Wherein, linkage 9 includes connecting rod and push rod, connecting rod connecting valve valve and push rod, and the push rod is adjusted with diffusion
Section disk 7 is connected, and spring structure is equipped with the push rod.
Adjustable back-to-back bilateral-pressure impeller turbocharger of the present invention is simple in construction, reliable, occupies little space, and can provide big model
The air inflow enclosed, meet the big engine of air inlet area requirement, and effectively save installing space.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
