In conjunction with reference to Fig. 4, first vortex 31 and the second vortex 32 engage each other and are formed with four cavitys, two of which cavity 33a be radially positioned at outside and radial symmetric, another two cavity 33b be radially positioned at inner side and diametrically, in cavity 33a, have air;

In conjunction with reference to Fig. 5, Fig. 5 is that relative second vortex 32 of the first vortex 31 revolves round the sun the state after 90 �� counterclockwise, vortex lines along the second vortex 32, two cavity 33b are combined into a cavity, the first corresponding for cavity 33a vortex 31 and the position of engagement of the second vortex 32 are moved to basic circle center, the volume making cavity 33a reduces, and the air in cavity 33a is compressed;

In conjunction with being that relative second vortex 32 of the first vortex 31 revolves round the sun the state after 180 �� counterclockwise with reference to Fig. 6, Fig. 6, the volume of cavity 33a reduces further, and air therein compresses further;

In conjunction with being that relative second vortex 32 of the first vortex 31 revolves round the sun the state after 270 �� counterclockwise with reference to Fig. 7, Fig. 7, the volume of cavity 33a further reduces, and air therein is further compressed;

In conjunction with reference to Fig. 8, Fig. 8 is that relative second vortex 32 of the first vortex 31 revolves round the sun the state after 360 �� counterclockwise, the volume of cavity 33a is reduced to the volume of cavity 33b shown in Fig. 4, volume of air in cavity 33a is compressed to minimum, afterwards, first vortex 31 is rotated further to state shown in Fig. 5, and when two cavity 33a are combined into a cavity, compressed air exports to gas off-take 210. In conjunction with reference to Fig. 5, in this condition, outside two cavity 33a, it is also formed with a pair semi-enclosed cavity 33c, air enters cavity 33c from air intake duct 220, afterwards along with the first vortex 31 revolves round the sun, with reference to Fig. 4��Fig. 8, the air in cavity 33c is compressed in most inner chambers and derives. In the first reciprocal process of revolution of vortex 31, in some cavitys that the first vortex 31 and the second vortex 32 surround, outermost cavity carries the cavity of air inner side extremely constantly, and air is compressed constantly and derives to cylinder. So, the air pressure compression process of the scroll machine supercharger of the present embodiment is performed continuously over, to realize the purpose of engine booster.

First, the scroll machine supercharger overall structure size particularly axial dimension of the present embodiment is very little, during scroll machine supercharger is not limited to, large-duty engine, may be used on the electromotor of various discharge capacity, and range of application is unrestricted. In actual applications, the axial dimension of the first vortex 31 and the second vortex 32 can be arranged according to application vehicle, such as when vehicle discharge capacity is bigger, first vortex 31 can be set and the second vortex 32 has larger axis to size, the cavity volume that first vortex 31 and the engagement of the second vortex 32 are formed is bigger, scroll machine supercharger air flow is relatively big, to meet the requirement of huge discharge.

Secondly, scroll machine supercharger is arranged in the side, bent axle place of electromotor, owing to the space of side, bent axle place is bigger, therefore the radial dimension of scroll machine supercharger has bigger extending space, can increase and decrease the number of turns of the first vortex 31 and the second vortex 32 as required to regulate the radial dimension of scroll machine supercharger. Such as when the number of turns of the first vortex 31 and the second vortex 32 is more, first vortex 31 and the second vortex 32 engage and form greater number of cavity, air in outermost cavity can be compressed to only small volume through bigger compression, to promote the boost pressure of scroll machine supercharger.

Furthermore, some cavitys that first vortex 31 and the second vortex 32 engage and surround, can be divided into several to radially symmetrical space, air in the outermost cavity that should have two radial symmetric is all compressed and is derived to gas off-take by each air pressure compression process, therefore scroll machine supercharger is high to the more existing mechanical supercharger of compression efficiency of air, the engine power consumed when obtaining identical boost pressure and pressurized air flow is less, the output making electromotor is bigger, promotes fuel economy.

Finally, first vortex and the second vortex engage each other and surround the cavity of multipair radial symmetric, in two radially symmetrical cavitys, wherein the air in a cavity radially each to pressure radially each with the air in another cavity to pressure cancel out each other, substantially without producing radial vibration between first vortex 31 and the second vortex 32, when scroll machine supercharger is worked steadily, vibration noise is very little, greatly improves the comfortableness of car load.

In the present embodiment, rotating disk 23 two ends vertically are respectively provided with the first vortex 31. But it is not limited to this, as variation, it may also is that be only provided with the first vortex in rotating disk one end vertically, correspondingly, two price fixings are first vortex circumference against price fixing be provided with the second vortex, second vortex and the engagement of the first vortex, now air intake duct and gas off-take are arranged on this second vortex place price fixing. It may also is that two first vortexes are two independent vortexes, but not same vortex, now each price fixing is provided with air intake duct and gas off-take, the gas off-take connection cylinder in two price fixings. It addition, in the present embodiment, the first vortex 31 and the second vortex 32 are single vortex lines vortex. In addition, as variation, the first vortex and the second vortex can be also binary vortices line vortex or many vortex lines vortex, and wherein the vortex lines of many vortex lines vortex are no less than 3. When the first vortex and the second vortex adopt binary vortices line vortex or many vortex lines vortex, then the number of cavities that the first vortex and the second vortex engage and surround is more, it is possible to improve scroll machine supercharger traveling comfort further.

With continued reference to Fig. 3, the first vortex 31 has the axial end 310 for 1 traverse of eccentric main axis, and the vortex lines drawn from this end 310 are around this end 310 vortex. Wherein, in the second side, axle 12 place, the first vortex 31 and the second vortex 32 engage each other in the position of corresponding second axle 12, have radial clearance between end 310 and the second axle 12, and during to allow the first vortex 31 to revolve round the sun, revolve round the sun around the second axle 12 in end 310. Correspondingly, in the first side, axle 11 place, the first vortex 31 and the second vortex 32 engage each other in the position of corresponding first axle 11.

In the present embodiment, in conjunction with reference to Fig. 2, Fig. 3, owing to two first vortexes 31 are same vortex, air intake duct 220 and gas off-take 210 can be in same price fixing, and are not limited to the layout of the present embodiment. It addition, in the present embodiment, air inlet 221 is positioned at the outer peripheral face of the second price fixing 22, and gas outlet 211 is positioned at the outer peripheral face of the first price fixing 21, but is not limited to this. If space allows, may be additionally located on the end face of price fixing as variation, air inlet and gas outlet. In the application, the air inlet position of scroll machine supercharger can be set according to the air inlet pipe position of the gas handling system of electromotor, arrange the position of the gas outlet of scroll machine supercharger according to the position of the air inlet pipe led in cylinder. Except position, the quantity of air intake duct and gas off-take is arranged also dependent on needs.

With continued reference to Fig. 3, the aperture of air intake duct 220 is more than the aperture of gas off-take 210. Air intake duct 220 aperture is bigger, it is possible to increasing the air inflow entering air intake duct 220, so eventually arrive at the air capacity in cylinder also more, the air capacity in cylinder is many, and the fuel oil in cylinder can be made fully to burn, and improves the output of electromotor. When air life after scroll machine compressed is hot and has stronger thermal expansion, the aperture of gas off-take 210 is less, is cause deformation for gas off-take 210 causes after avoiding thermal expansion air to pour in gas off-take 210 compressing. If the aperture of gas off-take 210 is relatively big, a large amount of thermal expansion air enter the air inlet pipe of connection cylinder, and air inlet pipe tube wall can bear relatively strong gas pressure for a long time and impact, and can accelerate to damage, reduce service life.

As it was noted above, the raw heat of air after scroll machine compressed, temperature is higher, therefore before passing into cylinder, needs first the high temperature air of compression to be cooled down. In the present embodiment, gas off-take 210 is connected with the charge air cooler of electromotor by gas outlet 211, the charge air cooler of electromotor can be first passed through from the pressurized air of gas off-take 210 derivation, derive to cylinder after charge air cooler absorbing and cooling temperature, to avoid overheated air early to fire before spark plug sprays electric spark. For obtaining good cooling radiating effect, in the present embodiment, with reference to Fig. 1, Fig. 2, the first price fixing 21 vertically dorsad the second price fixing 22 end face distribution have some radiating fins 10, second price fixing 22 vertically dorsad the first price fixing 21 end face distribution have some radiating fins 10, radiating fin 10 circumferentially direction on each price fixing is spaced apart, and some radiating fins are as air-turbocooler structure. The heat that pressurized air produces is transferred to some radiating fins 10 through rotating disk 23, two price fixing, radiating fin 10 energy augmentation of heat transfer, making the speed that heat transmits to radiating fin 10 increase, radiating fin 10 is lost in ambient atmosphere after absorbing heat, to play good radiating effect. So, the partial heat of the pressurized air in scroll machine supercharger is that some radiating fins 10 absorb and lose, the pressurized air derived from gas outlet 211 is before arriving charge air cooler, heat part is scattered and disappeared, temperature is reduced, this can alleviate the burden of engine intercooler, reduces the thermic load of the charge air cooler of electromotor. If space allows, it is possible to arrange radiating fin on the outer peripheral face of two price fixings.

In addition, as variation, it is also possible to be: change existing charge air cooler position, charge air cooler is installed to two price fixings and is exposed on the external on the end face in environment. Using as air-turbocooler structure, this can save electromotor installing space, improves the structural compactness of electromotor.

In the present embodiment, with reference to Fig. 2, Fig. 3, air intake duct 220 connects with chamber 20, the air of engine aspirating system output can enter in chamber 20, treat that the first vortex 31 revolution is engaged to the second vortex 32 afterwards, and surround radially open farthest away from the cavity of the first axis in axis line after, the air in chamber 20 enters this cavity farthest away from the first axis in axis line, and is compressed immediately. Wherein, the end face that first price fixing 21 in axial direction docks with the second price fixing 22 has groove 212, the second vortex 32 on first price fixing 21 is arranged in groove 212, and engage in groove 212 with the first corresponding vortex 31 when two price fixing docking, the axial dimension of the second vortex 32 and the first corresponding vortex 31 approximates depth of groove, offset with the bottom surface of the first vortex 31 after guaranteeing two price fixing docking with groove 212, and the end face of the second vortex 32 and rotating disk 23 offsets. Correspondingly, the end face that second price fixing 22 in axial direction docks with the first price fixing 21 has another groove (not shown), the second vortex 32 on second price fixing 22 is arranged in this groove, and engages in this groove with the first corresponding vortex 31. When the first price fixing 21 and the second price fixing 22 dock, two grooves of two price fixings are docking together and surround chamber 20. As variation, when scroll machine supercharger only has the first vortex and second vortex of pair of meshing, then only having groove in the second vortex place price fixing end face, the second vortex is in the grooves, in axial direction, this groove surrounds described chamber with the end face of another price fixing.

As mentioned before, two first vortexes 31 vertically respectively with the groove floor of price fixing between two against, substantially seamless gap between vortex lines and the groove floor of the first vortex 31, and, the end face axial of each second vortex 32 and rotating disk 23 against, substantially seamless gap between vortex lines and the end face of rotating disk 23 of the second vortex 32, this is that the cavity air for avoiding the first vortex 31 and the second vortex 32 to engage and surround is revealed, to improve compression efficiency. cavity for the first vortex 31 and corresponding second vortex 32 are surrounded better seals, in conjunction with reference to Fig. 2, Fig. 9, in the end face of the vortex lines rotating disk 23 dorsad vertically of the first vortex 31, end face axially towards rotating disk 23 of the vortex lines of the second vortex 32 is provided with sealing strip 30, sealing strip 30 on first vortex 31 forms excellent sealing between vortex lines and the groove floor of the first vortex 31, sealing strip 30 on second vortex 32 forms excellent sealing between the vortex lines and the end face of rotating disk 23 of the second vortex 32, the air in cavity is avoided to leak better. especially, thermal expansion after the air in cavity is compressed, it is easy to go out from the gap between vortex lines and the groove floor of the first vortex 31, between vortex lines and the end face of rotating disk 23 of the second vortex 32, and sealing strip 30 can seal this gap well to prevent air from going out, play good sealing effectiveness.

Except sealing effectiveness, sealing strip 30 also can strengthen between vortex lines and the groove floor of two price fixings of the first vortex 31, antiwear characteristic between vortex lines and rotating disk 23 end face of the second vortex 32, extends the service life of first vortex the 31, second vortex 32. The forming method of sealing strip 30 be may is that in the fabrication stage, seal groove can be set in the position of the first vortex 31 sealing strip 30 corresponding to the vortex lines of the second vortex 32, then polytetrafluoroethylmaterial material is injection-moulded in seal groove to form sealing strip 30.
