Fig. 6 is along the sectional view of the A-A line in Fig. 2 (B).Fig. 7 is along the sectional view of the B-B line in Fig. 3 (A).First, motor M is described.Motor M has coil 30, rotor 40, stator 50 and printed circuit board (PCB) PB etc.Stator 50 is metal parts.Stator 50 is fixed on the bottom wall portion 21f of crankcase 20.Stator 50 is wound with multiple coil 30.Coil 30 is electrically connected with printed circuit board (PCB) PB.Printed circuit board (PCB) PB is the parts being formed with conductive pattern on the substrate of the insulating properties with rigidity.Printed circuit board (PCB) PB is provided with not shown power connector for supplying electric power to coil 30 or signal connector and other electronic units.Such as, electronic unit is output transistor (switching element) or the capacitors etc. such as the FET (Field Effect Transistor: field effect transistor) of "on" position for control coil 30.By making coil 30 be energized, make stator 50 excitation.Printed circuit board (PCB) PB is supported in bottom wall portion 21f.
Rotor 40 has running shaft 42, yoke 44, one or more permanent magnets 46.Running shaft 42 is supported to can rotates by bearing BR1, BR2, and described bearing BR1, BR2 are held in upper wall portions 21e, bottom wall portion 21f respectively.Yoke 44 is fixed in running shaft 42 through lining 43, and yoke 44 rotates together with running shaft 42.Yoke 44 is metal parts.Yoke 44 comprises: wall portion 45f, and it is vertical with running shaft 42; Roughly cylindric surrounding wall portion 45s, itself and wall portion 45f are continuous.The inner peripheral surface 45e of surrounding wall portion 45s is fixed with one or more permanent magnets 46.Permanent magnet 46 is opposed with the outer circumferential face of stator 50.By making coil 30 be energized, make stator 50 excitation.Therefore, between permanent magnet 46 and stator 50, magnetic attraction and repulsion is acted on.By the effect of this magnetic force, rotor 40 rotates relative to stator 50.Like this, motor M is the motor of the external rotor type that rotor 40 rotates.Rotor 40 is external rotors.
Yoke 44 is described in detail.Outer circumferential face 45a, 45c of surrounding wall portion 45s are the round shape eccentric relative to the axis of rotation (hereinafter referred to as axis of rotation) of rotor 40.Outer circumferential face 45a, 45c stagger 180 degree relative to the eccentric direction of axis of rotation.The offset of outer circumferential face 45a, 45c is identical.The thickness of surrounding wall portion 45s is different according to position, makes outer circumferential face 45a, 45c become round shape relative to axis of rotation bias thus.Further, inner peripheral surface 45e is the shape concentric with axis of rotation.
Piston 25a, 25c link by means of bearing 25ar, 25cr and yoke 44 respectively.Therefore, piston 25a, 25c arranges diametrically relative to yoke 44, stator 50, coil 30, permanent magnet 46.Along with yoke 44 rotates to a direction, piston 25a, 25c move back and forth respectively in cylinder main body 12a, 12c.Piston 25a, 25c phase shifting separately 180 degree.
Cylinder main body 12a, 12c is fixed with respectively in the wall portion 21a of crankcase 20, the inner surface side of 21c.By making yoke 44 rotate, thus, the terminal part of piston 25a and cylinder main body 12a sliding contact.At this, delimit out chamber 13a by the wall portion 21a of the terminal part of piston 25a, cylinder main body 12a and crankcase 20.The volume of chamber 13a increases and decreases along with moving back and forth of piston 25a.Piston 25c and cylinder main body 12c is also identical structure.
As shown in (A) of Fig. 1, crankcase 20 is provided with nozzle N1, N2.Nozzle Nl, N2 are arranged at recess 28,29, and described recess 28,29 is arranged at the bight of crankcase 20.By making piston 25a, 25c move back and forth, by means of nozzle N1, air is imported in crankcase 20 thus.Intercommunicating pore 26a is provided with at the terminal part of piston 25a.The terminal surface of the terminal part of piston 25a is provided with the not shown valve member of opening and closing intercommunicating pore 26a.Between wall portion 21a, exhaust room 18a delimited by means of cylinder head 15a.Wall portion 21a chamber 13a and exhaust chamber 18a separated is provided with the intercommunicating pore 22a be communicated with exhaust chamber 18a by chamber 13a.Intercommunicating pore 22a is by being fixed on the not shown valve member opening and closing of the outer surface side of wall portion 21a.Piston 25c, cylinder head 15c, wall portion 21c, chamber 13c are formed too.
By moving back and forth of piston 25a, the volume of chamber 13a changes.Accompany therewith, air is imported in chamber 13a via intercommunicating pore 26a, thus the air in chamber 13a is compressed.Pressurized air is discharged to exhaust chamber 18a via intercommunicating pore 22a.As shown in figures 4-6, exhaust chamber 18a, 18c is communicated with via the hole 27H of the interconnecting part 27 formed in the inner side of crankcase 20.Exhaust chamber 18c is communicated with nozzle N2.Nozzle N2 is connected with pipe etc.
Cylinder 10c is also identical.Therefore, the air be imported in crankcase 20 via nozzle N1 is compressed by moving back and forth of piston 25a, 25c, and is discharged to the outside of crankcase 20 via nozzle N2.
As shown in Figure 6,7, piston 25a, 25c is positioned at the radial outside of rotor 40.Thus, compared with situation about arranging along the direction of axis of rotation with rotor 40, piston 25a, 25c, compressor A achieves miniaturization on the direction of axis of rotation.And, the length of running shaft 42 can be shortened in compressor A.Thus, the rigidity of running shaft 42 is improved, and can stably rotate.Thereby, it is possible to suppress the vibration etc. of motor M.
Because motor M is incorporated in crankcase 20, therefore the driving sound of motor M reduces.In addition, even if in the process driving compressor A, user also can when not contacting with motor M operate compressor A.
By making piston 25a, 25c link with outer circumferential face 45a, 45c of yoke 44 respectively, thereby, it is possible to make piston 25a, 25c along with the rotation of yoke 44 back and forth.In addition, the inner peripheral surface 45e of yoke 44 is concentric circles relative to the axis of rotation of rotor 40.In addition, the periphery of stator 50 also relative to the axis of rotation of rotor 40 in roughly concentric circles.Therefore, it is possible to the distance be fixed between the permanent magnet 46 of inner peripheral surface 45e and the periphery of stator 50 is kept roughly fixing.Thus, rotor 40 stably rotates.
Cylinder head 15a is substantially planar.In addition, the outside depression of the fixed air cylinder cap 15a of wall portion 21a, delimit exhaust room 18a by cylinder head 15a and wall portion 21a thus.About cylinder head 15c, wall portion 21c, also identical.Thus, cylinder head 15a, 15c need not define exhaust chamber 18a, 18c from crankcase 20 is significantly outstanding laterally with regard to drawing respectively.Thereby, it is possible to guarantee the area of the flat of the outer surface of compressor A, operation becomes easy.
Formed in the mode of the inner side projecting to the upper wall portions 21e of crankcase 20 by the interconnecting part 27 of exhaust chamber 18a, 18c connection is as shown in Fig. 4,6, and do not project to the outside of upper wall portions 21e.Thus, the outer surface of the upper wall portions 21e of crankcase 20 is smooth.Therefore, it is possible to guarantee the area of the flat of the outer surface of compressor A, operation becomes easy.
Nozzle Nl, N2 extend along identical direction, and extend along the direction vertical with upper wall portions 21e.Nozzle Nl, N2 are arranged at the recess 28,29 of crankcase 20 respectively, therefore, it is possible to suppress the overhang that nozzle Nl, N2 end is separately given prominence to from upper wall portions 21e.Thereby, it is possible to make compressor A integral miniaturization.In addition, as (B) of Fig. 2, Fig. 3 (B) shown in, the end of nozzle N1, N2 is configured to not give prominence to from upper wall portions 21e.Thus, the operation of compressor A becomes easy.
The maximum volume of the volume ratio chamber 13a of the exhaust chamber 18a delimited out by wall portion 21a and cylinder head 15a is little.For exhaust chamber 18c, chamber 13, also identical.By guaranteeing the maximum volume of chamber 13a, 13c, ensure that compression ratio.In addition, by less for the volume of exhaust chamber 18a, 18c of being discharged by the air compressed, therefore compressor A entirety achieves miniaturization.
As shown in Figure 7, cylinder main body 12a is configured in crankcase 20, and the wall portion 21a of crankcase 20 plays function as the portion of taking a seat of taking a seat for piston 25a.Equally, another wall portion 21c also plays function as the portion of taking a seat of taking a seat for piston 25c.Further, in order to avoid the impulsive sound produced when piston is taken a seat, piston can be made not exclusively to take a seat, but reserve small gap.Thus, in the direction that piston 25a, 25c move back and forth, in other words on the direction vertical with running shaft 42, the size of compressor A achieves miniaturization.
Such as, when the wall portion of crankcase being formed the escape hole of the size that piston can pass through and cylinder main body and cylinder head are arranged at the outside of crankcase, need to arrange space bar cylinder main body and cylinder head being separated and also play function as the portion of taking a seat.In this case, may maximize diametrically.
, as the present embodiment, wall portion 21a, the 21c of crankcase 20 play function respectively as the portion of taking a seat of piston 25a, 25c.Therefore, in the compressor A of the present embodiment, distance member as described above is not needed.Therefore, in the compressor A of the present embodiment, the direction that piston 25a, 25c move back and forth achieves miniaturization, and reduces number of components.
In addition, because the motor M of the present embodiment is external rotor type.When motor measure-alike, compare with inner-rotor type motor, the output that there is outer rotor motor becomes large trend.In other words, when exporting identical with inner-rotor type motor, outer rotor motor can realize miniaturization.Therefore, the motor M of the compressor A of the present embodiment achieves miniaturization.
As mentioned above, in compressor A, because piston 25a, 25c are positioned at the radial outside of rotor 40, motor M is incorporated in crankcase 20, cylinder main body 12A is fixed on the inner surface side of the wall portion 21a of crankcase 20 and cylinder head 15a is fixed on the outer surface side of wall portion 21a, and have employed the motor M of external rotor type, thus achieve miniaturization.
Further, for compressor A, make connect with air inlet side in the position of exhaust side connecting object device or make the installation direction of safety check and compressor A contrary, thus, compressor A plays function as vacuum machine.
In addition, using compressor A as in other situations that vacuum machine uses, by object-based device is connected with nozzle N2 side, thus as vacuum machine play function.In this case, the valve member be located in cylinder 10a can be the structure identical with the situation of compressor A.
(embodiment 2)
Next, the compressor B of embodiment 2 is described.Further, for the label that the component part identical, similar with the compressor A of embodiment 1 mark is identical, similar, and the repetitive description thereof will be omitted.Fig. 8 is the sectional view of the compressor B of embodiment 2.

At this, in yoke 44' rotation during driven plunger 25c, produce imbalance due to the driving of yoke 44' and piston 25c.This can think because the load such as the inertial force of yoke 44' and the counter-force moved back and forth of piston 25c produce.
In addition, for yoke 44', rotating center and position of centre of gravity are also different.Therefore, when yoke 44' rotates, produce uneven.Imbalance caused by the rotation of this yoke 44 and the imbalance caused by the rotation of balace weight bb are offset.Thus, even if in the compressor B being provided with independent piston 25c, the imbalance of overall torque also can be reduced.
Because balace weight bb is positioned at the radial outside of rotor 40', therefore, compared with situation about rotor 40', balace weight bb and running shaft 42 being linked in the mode arranged along axis of rotation direction, compressor B achieves miniaturization on axis of rotation direction.
Further, yoke 44' and balace weight bb also can be made to be molded as one.Also relative to axis of rotation providing holes asymmetrically on the wall portion 45f of yoke 44', balace weight bb can be replaced.That is, the wall portion 45f of yoke 44' also can be made to be formed as balace weight.In addition, also can on the wall portion 45f of yoke 44' fixed weight partly.
Fig. 9 is the sectional view of the compressor B' of the variation of embodiment 2.The surrounding wall portion 45s'' of yoke 44'' is only linked with piston 25c via bearing 25cr.Balace weight bb' is directly fixed on running shaft 42'.The eccentric direction of balace weight bb' is different from the eccentric direction of outer circumferential face 45c'.By such structure, the imbalance of overall torque also can be reduced.
Further, can one or more hole be set on wall portion 45f.Thereby, it is possible to reduce the imbalance of overall torque.If this structure, then the balace weight of point body component can not be set, also can weight reduction.Such as, also can on wall portion 45f, area peripheral edge providing holes between running shaft 42 and the terminal part of piston 25c.Such as, also multiple hole can be set in the circumference of wall portion 45f.
In addition, also on the basis of balace weight bb' being directly fixed on running shaft 42', also other balace weight can be fixed on yoke 44''.
