Specific embodiment：

The present invention provides a kind of rotating boosting pump, including the housing 1 that internal structure is cylindric cavity, in 1 cavity of housing Front end be provided with end cap 2, the sucking of connection housing cavity is provided on end cap 2 with head piece 3 and outlet 12, feature It is：Rotating boosting pump further includes rotor block, and rotor block includes driving wheel 4 and driven wheel 5, and driving wheel 4 is arranged on housing 1 Interior, outer wall and the tangent dynamic cooperation of 1 cavity interior walls of housing of driving wheel 4, the inside of driving wheel 4 is reentrant cylindrical cavity, and driven wheel 5 is set It puts in the cavity 6 of driving wheel 4, is formed between the center O1 of the center O2 of the support shaft 7 of driven wheel 5 and the main shaft 8 of driving wheel 4 Eccentric e；

5 outer wall of driven wheel cooperatively forms dynamic sealing tangent line a with tangent move of 4 cavity interior walls of driving wheel, and removing for driven wheel is dynamic close Cavity is formed between 4 cavity interior walls of outer wall and driving wheel beyond sealing line a；Driving wheel 4 and driven wheel 5 move close with end cap 2 Envelope；

Driven wheel 5 is more wheel constructions that at least two driven wheels are formed, and is contacted between adjacent two driven wheels and forms energy The movable sealing structure mutually rotated, wherein the first driven wheel 10 is single chip architecture, the second driven wheel 11 and other driven wheels are Paired structure, the first driven wheel 10 are clipped between the paired structure of the second driven wheel 11, the second driven wheel 11 be clipped in the 3rd from Between the paired structure of driving wheel, and so on；

It is provided in the side wall of 4 cavity of driving wheel along the diametric slot H of cavity, quantity and the driven wheel 5 of slot H Quantity corresponds to, and one end of each slot H connects as connecting pin each via a rotating vane 9 with the activity of corresponding driven wheel It connects, dynamic sealing coordinates between all rotating vanes 9 and corresponding slot H connecting pins, and all rotating vanes 9 are and driven wheel Dynamic sealing connects, and contacts with each other and can relatively rotate between adjacent driven wheel, and matches somebody with somebody between adjacent driven wheel for dynamic sealing It closes；

It is dynamic sealing between driven wheel 5 and the cavity blind end of driving wheel 4 and between driven wheel 5 and end cap 2, rotation It is dynamic sealing between blade 9 and the cavity blind end of driving wheel 4 and between rotating vane 9 and end cap 2；

The cavity 6 of driving wheel 4 is separated into multiple independences after being connected between multiple rotating vanes 9 and slot H and driven wheel 5 Chamber；Wherein with sucking the chamber connected with head piece 3 as intake chamber, other chambers are connected with the outlet 12 on end cap；

By taking Fig. 1 as an example, three separate chambers i.e. I that the embodiment of the present invention is simultaneously formed for rotor block rotation process, II, Ⅲ.Wherein each separate chamber can be undergone with the rotation of driving wheel changes from small to big, then from large to small in cycles Process when the volume of separate chamber changes from small to big and is connected with sucking with head piece 3, becomes intake chamber（Such as I in Fig. 1）, It at this point, other chambers are from large to small, is connected as discharge chamber with outlet 12, at this point, the discharge chamber and sucking flow It is not connected between mouth 3；

By taking Fig. 1 as an example, I volume of chamber changes from small to big, chamber II, III volume are distinguished from large to small；Separate chamber volume week The variation of phase property realizes the course of work for constantly sucking fluid, constantly excluding.

Driven wheel 5 is two, and including the first driven wheel 10 and the second driven wheel 11, it is driven that the first driven wheel 10 is clipped in second Dynamic sealing coordinates between the paired structure of wheel 11.

Outlet 12 is along the arc-shaped of discharge chamber setting.

Operation principle of the present invention is as shown in Figure 1 when main shaft 8 drives rotor block to turn around centre of gyration O1 by shown by arrow direction When dynamic, compressed gas chamber（II He in figure）Volume is from large to small；I volume of chamber changes from small to big, and fluid media (medium) is through inhaling Enter and constantly enter chamber I with head piece；Compressed gas chamber（II He in figure）Compression supercharging is discharged by outlet 12. So moved in cycles so as to fulfill the course of work.
