Further, as shown in Figure 1, bent axle 36 and rotor 22 are fixing with rotor 22 synchronous rotary, bent axle 36 runs through main bearing 31, cylinder 33 and supplementary bearing 32, bent axle 36 is arranged with piston, piston is positioned at cylinder 33, rotor 22 driving crank 36 rotates to drive piston to make eccentric motion in cylinder 33, thus the refrigerant entered in cylinder 33 is compressed, first refrigerant after overcompression can be drained in main baffler 34 by main bearing 31, being drained in the space between main baffler 34 and motor 2 by main baffler 34.
With reference to Fig. 1, bent axle 36 is formed with center oilhole 361, one end away from motor 2 (lower end such as shown in Fig. 1) of center oilhole 361 is opened wide, and bent axle 36 is formed communicates with center oilhole 361 and to run through the side direction oilhole 362 of bent axle 36 sidewall, side direction oilhole 362 is between the upper-end surface of main bearing 31 and the bottom surface of rotor 22.
As shown in Figure 1, center oilhole 361 is formed as coaxial cylindrical with bent axle 36, and center oilhole 361 is formed by the recessed straight up at least partially of lower end surface of bent axle 36, side direction oilhole 362 can be multiple, and multiple side direction oilhole 362 can be evenly spaced apart each other along the circumference of bent axle 36, each side direction oilhole 362 all runs through the sidewall of bent axle 36 along the radial level from bent axle 36, and ensure that each side direction oilhole 362 Jun Yu center oilhole 361 is connected, wherein, the top of side direction oilhole 362 contiguous center oilhole 361, and the outer end of each side direction oilhole 362 is all located between the lower end surface of rotor 22 and the upper-end surface of main bearing 31.
Further, with reference to Fig. 1, oiling blade 35 can be provided with in center oilhole 361, thus the refrigerator oil bottom housing 1 in oil sump 11 can under the driving of oiling blade 35, move upward with lubricate compressors structure 3 along center oilhole 361, the gaseous coolant of separating out in the part in this refrigerator oil and this refrigerator oil is discharged by the side direction oilhole 362 on bent axle 36 again, and between the main bearing 31 entered in housing 1 and motor 2, along with the increase of rotary compressor 100 rotating speed, the corresponding sharp increase of oil pump capacity of side direction oilhole 362.
Further, director valve 4 is located in center oilhole 361, and director valve 4 comprises assembly department 41 and valve block portion 42, and valve block portion 42 is located on assembly department 41.As shown in Figure 2 and Figure 4, director valve 4 can be arranged in center oilhole 361 by forward (free end in the valve block portion 42 such as shown in Fig. 4 extends straight up), can also swing to (free end in the valve block portion 42 such as shown in Fig. 2 extends straight down) is arranged in center oilhole 361, when director valve 4 forward is arranged in center oilhole 361, valve block portion 42 extends (as shown in Figure 4) straight up from the upper-end surface of assembly department 41 and opens with the perisporium internal and external partition of center oilhole 361; When director valve 4 swing to be arranged in center oilhole 361 time, valve block portion 42 extends (as shown in Figure 2) straight down from the lower end surface of assembly department 41 and opens with the perisporium internal and external partition of center oilhole 361, particularly, assembly department 41 is fixed on the perisporium of center oilhole 361, thus assembly department 41 can with bent axle 36 synchronous rotary, namely there is no relative displacement between assembly department 41 with center oilhole 361 or relatively to rotate.
With reference to Fig. 4 composition graphs 7 and Fig. 9, valve block portion 42 relative with side direction oilhole 362 at least partly, the axial direction that valve block portion 42 is arranged to when motor 2 driving crank 36 rotates around spin axis relative to bent axle 36 departs from towards the direction of side direction oilhole 362.Particularly, the one end be connected with assembly department 41 in valve block portion 42 is fixed end, the other end in valve block portion 42 is free end, the free end in valve block portion 42 is relative with side direction oilhole 362 in the circumference of bent axle 36, when bent axle 36 is static, the free end in valve block portion 42 and the perisporium internal and external partition of center oilhole 361 are opened, when rotating shaft drives director valve 4 synchronous axial system, the free end in valve block portion 42 moves towards the perisporium direction of center oilhole 361 due to the effect of centrifugal force, because the free end in valve block portion 42 is relative with side direction oilhole 362, thus valve block portion 42 can shaded portions side direction oilhole 362, namely the aperture of side direction oilhole 362 is reduced, that is, reduce the cross-section area of side direction oilhole 362, thus reduce the oil pump capacity of side direction oilhole 362.
Here, it should be noted that, the centrifugal force that the free end in valve block portion 42 produces is F, F=mr ω 2, wherein, m is the quality of director valve 4, and r is the turning radius of director valve 4, ω is the angular velocity of rotation of director valve 4, can draw thus, the angular velocity of rotation of director valve 4 is larger (namely the rotating speed of bent axle 36 is higher, or the rotating speed of rotary compressor 100 is larger), the centrifugal force that the free end in valve block portion 42 produces is larger, and valve block portion 42 is the closer to side direction oilhole 362.
Like this, valve block portion 42 can according to the rotating speed of rotary compressor 100 (i.e. the rotating speed of bent axle 36), the aperture (namely regulating the oil pump capacity of side direction oilhole 362) of automatic adjustment side direction oilhole 362, when the rotating speed of bent axle 36 is higher, the centrifugal force that the free end in valve block portion 42 produces is larger, the amount of deformation of free end on centrifugal direction in valve block portion 42 is larger, that is, valve block portion 42 more departs from towards the perisporium direction of center oilhole 361, namely valve block portion 42 more moves towards the direction of side direction oilhole 362 corresponding thereto, thus the part of the inner of side direction oilhole 362 block by valve block portion 42.Thus, reduce the aperture of side direction oilhole 362, reduce the valid circulation area of side direction oilhole 362, thus reasonably control the oil pump capacity of side direction oilhole 362, when preventing rotary compressor 100 high frequency from running, a large amount of refrigerator oils is pumped out oil sump 11, so improve rotary compressor 100 tell oily rate and pasta stability.
According to the rotating speed of the rotary compressor 100 of the embodiment of the present invention, by arranging director valve 4, thus the aperture of side direction oilhole 362 and the valid circulation area of side direction oilhole 362 can be regulated, reasonably control the oil pump capacity of side direction oilhole 362, when preventing rotary compressor 100 high frequency from running, a large amount of refrigerator oils is pumped out oil sump 11, and then improves the pasta stability of telling oily rate and oil sump 11 of rotary compressor 100.
In one embodiment of the invention, assembly department 41 is formed with at least one through through hole 411.Such as in the example of Fig. 5 and Fig. 6, assembly department 41 is roughly horizontally disposed cylindrical, through hole 411 runs through assembly department 41 along the axial direction of assembly department 41, thus assembly department 41 is formed as ring, assembly department 41 is engaged in center oilhole 361, and the periphery wall of assembly department 41 is connected on the perisporium of center oilhole 361, alternatively, assembly department 41 can together with center oilhole 361 interference fit.
Thus, the refrigerator oil being mixed with gaseous coolant enters into after in center oilhole 361, bent axle 36 can be discharged by through hole 411 and side direction oilhole 362, thus avoid this part gaseous coolant cumulative at center oilhole 361 top, avoid causing the problem that the refrigerator oil liquid level pumped in center oilhole 361 is too low, ensure compressing mechanism 3 sufficient lubrication, ensure that rotary compressor 100 can normally work.
Certainly, the present invention is not limited thereto, assembly department 41 can also be formed as other shapes, such as in the example of fig. 8, assembly department 41 is spliced by three rectangular flats, one of them rectangular flat horizontal positioned, another two rectangular flats extend straight up from two relative edges of this horizontal plate, thus be formed as the cube that top is opened wide and two other side is all opened wide, when assembly department 41 is arranged in center hole, the perisporium of center oilhole 361 and the sidewall of assembly department 41 spaced apart at least partially, thus the refrigerator oil ensureing to be mixed with gaseous coolant enters into after in center oilhole 361, can by the gap between assembly department 41 and center oilhole 361 perisporium, and discharge bent axle 36 from side direction oilhole 362.Here, it should be noted that, in center oilhole 361, can also the devices such as fixing buckle be set, to make assembly department 41 fixed.
In addition, the cross section of center oilhole 361 can also be formed as other shapes, and the shape of assembly department 41 specifically can also be arranged according to the shape of cross section of center oilhole 361, to meet actual requirement better.
Further, valve block portion 42 comprises: body 421 and protruding 422, body 421 extends along the axis of bent axle 36, the fixed end of body 421 is connected with assembly department 41, protruding 422 are located at the free end of body 421 and are positioned at the side of adjacent side to oilhole 362 of body 421, and its protrusions 422 is relative with side direction oilhole 362.As shown in Figure 5, assembly department 41 is ring, body 421 is arc plate, and body 421 extends straight up along the inner circle wall of assembly department 41, the upper end of body 421 is formed with protruding 422, protruding 422 protrude from the radially outward of the outer surface of assembly department 41 centrally oilhole 361, and protruding 422 corresponding in the circumference of center oilhole 361 with side direction oilhole 362.Here, it should be noted that, " interior " can be understood as the direction towards bent axle 36 center, and its opposite direction is defined as " outward ", namely away from the direction at bent axle 36 center.
Certainly, the present invention is not limited thereto, with reference to Fig. 8, when assembly department 41 is formed as cube top and two sides all opened wide, body 421 can be dull and stereotyped, the top of two vertical plates of assembly department 41 is formed with the flange of inside horizontal-extending respectively, and body 421 extends straight up from the inner of two flange, with spaced apart with the perisporium of center oilhole 361.
Alternatively, protruding 422 is salient point 4221, and the shape of cross section of salient point 4221 is preferably identical with the shape of cross section of side direction through hole 411.Such as in the example of fig. 8, protruding 422 is hemisphere, and horizontally outward protrudes from the outer surface of plate shaped body 421, and certainly, the present invention is not limited thereto, salient point 4221 can also be formed as semielliptical shape, or polyhedron etc.
Or alternatively, body 421 is arc plate, projection 422 is the convex tendon 4222 that the circumference of arcuately plate extends.Such as in the example of Fig. 5 and Fig. 6, the upper end-face edge of convex tendon 4222 arcuately plate horizontally outward protrudes, and the cross section of convex tendon 4222 is semicircle, certainly, the cross section of convex tendon 4222 can also be formed as half elliptic, half long-round-shape and polygonal etc., now, the shape of side direction oilhole 362 and the shape of convex tendon 4222 can not be identical.Certainly, the present invention is not limited thereto, arc plate can also arrange salient point 4221.
Further, the maximum cross-section area of salient point 4221 is less than the cross-section area of side direction oilhole 362.Such as in the figure 2 example, salient point 4221 is hemisphere, along from the sidewall of body 421 to the direction of corresponding side direction oilhole 361, the cross-section area of salient point 4221 reduces gradually, the cross-section area of side direction oilhole 362 is circular, the cross-section area of side direction oilhole 362 is greater than the cross-section area of salient point 4221 and body 421 sidewall connecting place, thus, when the free end centrifugal motion in valve block portion 42, even if the unlimited perisporium near center oilhole 361 of the outer surface of body 421, salient point 4221 is also unlikely to complete closed side to oilhole 362, can ensure that gaseous coolant is discharged from side direction oilhole 362 thus, and reduce the aperture of side direction oilhole 362, and then reasonably control the oil pump capacity of side direction oilhole 362.
In addition, during due to valve block portion 42 centrifugal motion, body 421 tilts to extend from inside to outside, and the lower end of such salient point 4221 and the lower end of side direction oilhole 362 have certain angle, thus salient point 4221 can be avoided further by complete for side direction oilhole 362 totally enclosed problem.So, be understandable that, the maximum cross-section area of convex tendon 4222 is also less than the cross-section area of side direction oilhole 362.
In addition, except the amount of deformation by controlling valve block portion 42 according to the rotating speed of bent axle 36 mentioned above, can also the centrifugal force in valve block portion 42 be controlled by regulating the quality of protruding 422 and then regulate the amount of deformation in valve block portion 42, and control the aperture of side direction oilhole 362, regulate the oil pump capacity of side direction oilhole 362.
Alternatively, as shown in Figure 5 and Figure 6, valve block portion 42 is one or more, and the quantity in valve block portion 42 is less than or equal to the quantity of side direction oilhole 362.That is, have at least a side direction oilhole 362 to have valve block portion 42 corresponding thereto, thus director valve 4 at least can control the aperture of a side direction oilhole 362, adjusts oil mass.Preferably, the quantity in valve block portion 42 is equal with the quantity of side direction oilhole 362, thus director valve 4 can regulate the oil pump capacity of side direction oilhole 362 better.
Preferably, with reference to Fig. 6, valve block portion 42 is two, and two valve block portions 42 are about the spin axis Central Symmetry of bent axle 36.Thus, the rotational stability of director valve 4 can be ensured.
Such as in the example of fig. 6, valve block portion 42 is for being provided with the arc plate of convex tendon 4222, and the length of convex tendon 4222 equals the length of corresponding arc plate, like this, when bent axle 36 is provided with two relative side direction oilholes 362, two convex tendons 4222 can be relative with a side direction oilhole 362 respectively, to regulate the oil pump capacity of two side direction oilholes 362 simultaneously, when bent axle 36 be provided with multiple be spaced apart from each other and equally distributed side direction oilhole 362 time, two convex tendons 4222 can be relative with multiple side direction oilhole 362 respectively, certainly, some side direction oilholes 362 also may be had not relative with any one in these two convex tendons 4222, when director valve 4 rotary work, the oil pump capacity of the side direction oilhole 362 relative with two convex tendons 4222 can be regulated.
Such as in the example of fig. 8, valve block portion 42 is for being provided with the flat board of salient point 4221, and each flat board is only formed by a salient point 4221, like this, when bent axle 36 is provided with two relative side direction oilholes 362, or be provided with multiple be spaced apart from each other and equally distributed side direction oilhole 362 time, the side direction oilhole 362 that two salient points 4221 are only relative with two is relative, when director valve 4 rotary work, the oil pump capacity of two the side direction oilholes 362 relative with two salient points 4221 can be regulated.
