Below the structure of the back pressure oil groove of the application is described.As shown in figures 4-9, be the application's scheme clutch shaft bearing 31 on back pressure tank structure, back pressure oil groove 71 is mainly divided into inspiratory limb 711, compressing section 712 and exhaust section 713, the corresponding cylinder suction location of inspiratory limb 711 and forward part compression angle, connect oil duct 311 to be directly connected with inspiratory limb 711, now the gas pressure that is subject to of slide plate 8 head 81 is less, does not need high back pressure; The corresponding rear section compression in compressing section 712 angle, now slide plate 8 head 81 is subject to larger gas pressure, and higher back pressure guarantee slide plate 8 need be provided not return vane slot 61 by pressure; The corresponding exhaust position angle of exhaust section 713, now the gas pressure that is vented of slide plate 8 head 81, needs the back pressure guarantee slide plate 8 being greater than exhaust pressure not return vane slot 61.For this reason, be set to that there is different cross-section areas by three of back pressure oil groove 71 sections, the cross-section area of wherein said inspiratory limb 711 is greater than the cross-section area of described compressing section 712, and/or the cross-section area of described compressing section 712 is greater than the cross-section area of described exhaust section 713, and/or the cross-section area of described inspiratory limb 711 is greater than the cross-section area of described exhaust section 713.
As one preferably mode of execution, the cross-section area of described inspiratory limb 711, described compressing section 712 and described exhaust section 713 reduces successively.Preferably, described inspiratory limb 711, described compressing section 712 are identical with the degree of depth of described exhaust section 713, and its groove width width reduces successively, and namely the groove width of inspiratory limb 711 is maximum, and the groove width of compressing section 712 is taken second place, and the groove width of waiting section 713 is minimum, as shown in Figure 6.
Preferably, clutch shaft bearing 31 and the second bearing 32 are respectively equipped with back pressure oil groove 71,72, as shown in Figure 3, slide plate 8 can be made along the both sides uniform force of main shaft 21 axial direction, can the inclination of anti-slip limiting plate 8, ensure the reliability that slide plate 8 works.
Introduce the principle in each stage below respectively:
In inspiratory limb 711, because the gas force that now slide plate 8 head 81 is subject to is pressure of inspiration(Pi), therefore slide plate 8 afterbody 82 does not need too large back pressure, to come and first oil through restrictor 4 reducing pressure by regulating flow arrive inspiratory limb 711 from connecting oil duct 311, because back pressure oil have passed through reducing pressure by regulating flow, excessive head 81 power consumption that causes of slide plate 8 afterbody 82 back pressure can not be caused to increase.
In compressing section 712, the power that now slide plate 8 head 81 is subject to is through the gas force of certain compression, therefore comes from inspiratory limb 711 and may can not meet pressure now through the oil of reducing pressure by regulating flow.The application's scheme utilizes now slide plate 8 to be do the recoil movement that the axis direction to main shaft 21 moves, as Fig. 8, slide plate 8 moves to position B from position A, the volume in vane slot tail chamber 610 can reduce along with corner change, by the cross-section area of compressing section 712 is reduced, because slide plate 8 angular velocity is very fast, the drainage area of back pressure oil groove diminishes, oil in vane slot tail chamber 610 can not be vented by back pressure oil groove at once, so the oil of inside, vane slot tail chamber 610 can have certain decrement due to vane slot tail diminishing of volume of chamber 610, be equivalent to increase to back pressure oil, thus ensure that in vane slot tail chamber 610 now, back pressure increases.
At exhaust section 713, principle and compressing section similar, as Fig. 9, slide plate 8 moves to position D from position C, also be that the cross-section area in vane slot tail chamber 610 when utilizing slide plate 8 to return reduces to increase back pressure oil oil pressure, due to also little than compressing section 712 of the cross-section area of exhaust section 713, be equivalent to the drainage area further reducing back pressure oil groove, simultaneously because the volume in vane slot tail chamber 610 diminishes further, thus larger oil pressure can be produced in vane slot tail chamber 610.
Can be controlled the oil pressure of compressing section 712 and exhaust section 713 by the cross-section area controlling back pressure groove, thus both ensure that two stage slide plate 8 afterbodys 82 had enough back pressures.
Described back pressure oil groove 71 can be through annular pass, also can be the not through curve bath disconnected, as known from prior art.When back pressure oil groove 71 is curve baths, in inspiratory limb and compressing section, back pressure oil groove 71 is communicated with vane slot tail chamber 610, is not communicated with vane slot tail chamber 610 at the confined area back pressure oil groove of exhaust section.As one preferably mode of execution, described inspiratory limb 711, described compressing section 712 and described exhaust section 713 form through annular pass, at exhaust section 713, do not deposit confined area in the introduction, vane slot tail chamber 610 is connected with hydraulic pressure oil groove 71 all the time, can be drained by annular pass when the oil pressure in vane slot tail chamber 610 is too high, the situation avoiding back pressure excessive occurs, reduces in the friction of exhaust section slide plate 8 with cylinder 5.In addition, the application's scheme is in the compressor start stage, because back pressure oil groove 71 is annular pass-through, the negative pressure in the vane slot tail chamber 610 that slide plate 8 stretches out and causes can stay remaining gas to supplement at any time by working connection 22, reduce the negative pressure in vane slot tail chamber 610, be conducive to stretching out of slide plate 8 when compressor just starts, ensure that the followability of slide plate 8.
