In one embodiment of the invention, flow control device 5 is arranged in slide plate 25 and is communicated with first end and the second end and cuts off first end and the second end at slide plate 25 during to direction motion near bent axle 3 central axis to direction when motion of deviating from bent axle 3 central axis.As shown in Figure 1, because the eccentric part of bent axle 3 rotates, thereby drive slide plate 25 interior reciprocating at vane slot 211, particularly, in breathing process, slide plate 25 is towards direction (being the direction of the central axis of the bent axle 3) motion of rotating center, now vane slot 211 is stretched out in the inner of slide plate 25, and it is large that the space in vane slot 211 becomes, and refrigerator oil is inhaled in vane slot 211 by oil-sucking hole 41; In exhaust process, slide plate 25 is towards the direction motion away from rotating center, now the inner of slide plate 25 retraction, space in vane slot 211 diminishes, refrigerator oil in vane slot 211 enters oily cap 7 by oil feed line 4, arrive the center oilhole 31 of bent axle 3, and enter cylinder 21 assemblies from bent axle 3 Shang center oilholes 31, with lubrication and seal cylinder 21 assemblies.In the course of the work, the continuous to-and-fro motion of slide plate 25, cyclically inhales, arranges refrigerator oil to horizontal rotary compressor 100, refrigerator oil is sent to the center oilhole 31 of bent axle 3 by oil feed line 4, finally arrives cylinder 21 assemblies.
In one embodiment of the invention, oil feed line 4 has flow control pipeline section 42, and flow control pipeline section 42 is located between oil-sucking hole 41 and the second end of oil feed line 4, first end in flow control pipeline section 42 (for example, Fig. 1, one end of contiguous sealing plate 6 in Fig. 3 and Fig. 5) be provided with Sealing 421, and the second end in flow control pipeline section 42 (for example, Fig. 1, one end of the oily cap 7 of vicinity in Fig. 3 and Fig. 5) be provided with at least one stop member 422, flow control device 5 is rolling element, rolling element is located in flow control pipeline section 42, and rolling element can roll between Sealing 421 and stop member 422.With reference to Fig. 1, Fig. 3 and Fig. 5, Sealing 421 and stop member 422 are located in flow control pipeline section 42, and lay respectively at flow control pipeline section 42 along its axial two ends, for example ball of rolling element can roll back and forth between Sealing 421 and stop member 422, when slide plate 25 is in the time that the direction of the central axis away from bent axle 3 is moved, the ball that refrigerator oil in vane slot 211 can promote in flow control pipeline section 42 moves towards the direction of stop member 422, in the time that ball and stop member 422 only supports, ball no longer moves towards the direction of center oilhole 31 with respect to stop member 422, refrigerator oil can enter in the center oilhole 31 of bent axle 3 by the gap between ball and stop member 422, when slide plate 25 is in the time that the direction of the central axis of bent axle 3 is moved, refrigerator oil in center oilhole 31 can promote the direction motion of ball towards Sealing 421, in the time that ball and Sealing 421 only supports, ball no longer moves towards the direction of vane slot 211 with respect to Sealing 421, now seal up the first end of flow control pipeline section 42 completely due to ball, thereby the refrigerator oil in center oilhole 31 can not enter in vane slot 211 by oil feed line 4, thereby promote the fuel delivery of oil feed line 4.In addition, by flow control pipeline section 42 is arranged on oil-sucking hole 41 on oil feed line 4 and and one end of being connected of the center oilhole 31 of bent axle 3 between, thus, when slide plate 25 is in the time that the direction of the central axis of bent axle 3 is moved, ball and stop member 422 only support, the refrigerator oil entering in center oilhole 31 not only cannot flow towards the direction of the first end of oil feed line 4, nor can flow out from oil-sucking hole 41, thereby has further improved the fuel delivery of oil feed line 4.
Here, it should be noted that, flow control pipeline section 42 can be arranged on the arbitrary position on oil feed line 4, for example flow control pipeline section 42 can be arranged on the middle part of oil feed line 4, as shown in Figure 3, or also can be arranged on one end (for example, the second end in Fig. 5) of oil feed line 4.It will be appreciated that, quantity, shape and the arrangement etc. of stop member 422 can be according to actual requirement settings, to meet better actual requirement.
Alternatively, as shown in Figure 3 and Figure 5, flow control pipeline section 42 is become and is formed greatly by a part of cross-section area of fuel supply line, and one end being communicated with vane slot 211 of the contiguous fuel supply line of flow control pipeline section 42 forms Sealing 421.For example, in the example of Fig. 3 and Fig. 5, the transverse dimension of flow control pipeline section 42 is greater than the transverse dimension of the other parts of fuel supply line, and the diameter of ball should be greater than the transverse dimension of the other parts of fuel supply line, wherein, Sealing 421 from the first end of flow control pipeline section 42 (is for example, right-hand member in Fig. 5) to the second end of flow control pipeline section 42 (for example, left end in Fig. 5) loop configuration that increases gradually of cross-section area, now Sealing 421 is roughly cone cylinder body shape, when slide plate 25 is in the time that the direction of the central axis of bent axle 3 is moved, ball can contact with the internal surface of Sealing 421, thereby by the first end sealing of flow control pipeline section 42, good sealing effect and easy to process.In another example of the present invention, the internal surface of Sealing 421 can also be formed as planar annular, and this planar annular can substantially vertical with the central axis of fuel supply line (scheming not shown).
Certainly, the invention is not restricted to this, Sealing 421 can also be formed as annular shape, and the outer end of Sealing 421 is connected on the internal face of flow control pipeline section 42 (scheming not shown).For example, Sealing 421 is located in fuel supply line, and the outer ring of the Sealing 421 of annular can be connected on the inner peripheral surface of fuel supply line, the inner ring of Sealing 421 extends towards the direction at fuel supply line center, now the plane at Sealing 421 places can be vertical with the central axis of fuel supply line, or to form with the central axis of fuel supply line be not the angle of 90 °.Here, it should be noted that, direction " outward " can be understood as the direction towards Sealing 421 centers, and its contrary direction is defined as " interior ", away from the direction at Sealing 421 centers.
Alternatively, at least one stop member 422 is for being located at backstop thorn or the stopper protrusion in flow control pipeline section 42.For example, in the example of Fig. 3, stop member 422 is backstop thorn, now backstop thorn can be inwardly concaved and be formed by a part for the outer wall of flow control pipeline section 42, backstop thorn is formed at cross-section area in direction from inside to outside and increases gradually, in the time that refrigerator oil in fuel supply line drives rolling element for example ball is towards the direction motion of the second end of fuel supply line, backstop thorn can block ball, prevents that ball from continuing to move towards the center of bent axle 3 oilhole 31.Further, backstop thorn is for multiple, and multiple backstop thorn being circumferentially spaced apart from each other along flow control pipeline section 42.Four stop members 422 have for example been shown in the example of Fig. 5 and Fig. 6, four stop members 422 are evenly distributed on the inner circle wall of described fuel supply line, and four stop members 422 are stopper protrusion, now each stopper protrusion inwardly concaves formation by a part for the outer wall of flow control pipeline section 42, in the time that refrigerator oil in fuel supply line drives rolling element for example ball is towards the direction motion of the second end of fuel supply line, stopper protrusion can be blocked ball, prevents that ball from continuing to move towards the center of bent axle 3 oilhole 31.
In one embodiment of the invention, flow control device 5 is located between the first end and oil-sucking hole 41 of oil feed line 4.Alternatively, flow control device 5 is made up of a part for oil feed line 4, and flow control device 5 is configured to reduce gradually (scheming not shown) from the first end of oil feed line 4 to the second end cross-section area of oil feed line 4.Now, flow control device 5 is roughly conical pipe and is the part of oil feed line 4, and this flow control device 5 can play the effect of throttling, is conducive to reduce slide plate 25 and from oily cap 7, sucks back refrigerator oil when towards the direction motion of the central axis of bent axle 3.
In one embodiment of the invention, flow control device 5 is flange, and flange is located in oil feed line 4 and is positioned at oil-sucking hole 41 places, as shown in Fig. 7-Fig. 9.For example, in the example of Fig. 7-Fig. 9, flange is concordant with the edge of oil-sucking hole 41, and extend towards the direction at oil feed line 4 centers from the edge of oil-sucking hole 41, thus, by flange is set, ensure fuel delivery, and in oil extraction process, due to the impact of flange, refrigerator oil in vane slot 211 only has can enter oil sump 11 on a small quantity, and in the most of center oilhole 31 that feeds bent axle 3 of the refrigerator oil sucking in fuel feeding process, thereby effectively improve fuel feeding efficiency, ensured the reliability of horizontal rotary compressor 100.
Certainly, in another example of the present invention, flange can also arrange around oil-sucking hole 41 (scheming not shown), and now the marginating compartment of flange and oil-sucking hole 41 is opened certain distance, and the cross-section area of flange is greater than the area of oil-sucking hole 41.In some examples more of the present invention, flange can also be multiple, and multiple flange is in the setting (scheming not shown) that is upwards spaced apart from each other in the week of oil-sucking hole 41.
For example, in a specific embodiment of the present invention, with reference to Fig. 5 and Fig. 6, the first end of oil-sucking hole 41 contiguous oil feed lines 4 is arranged, flow control pipeline section 42 is formed on the second end of oil feed line 4, and the first end of flow control pipeline section 42 has the Sealing 421 of the truncated conical shape of being formed as, and the second end of flow control pipeline section 42 is formed with four stopper protrusion, four stopper protrusion were upwards uniformly distributed in the week of flow control pipeline section 42, and ball is located between Sealing 421 and four stopper protrusion.
In the time that the refrigerator oil in vane slot 211 enters the center oilhole 31 of oily cap 7 and bent axle 3 by oil feed line 4, ball is towards the direction motion of four stopper protrusion, thereby the first end of oil feed line 4 and the second end are communicated with, and do not affect center oilhole 31 fuel feeding of vane slot 211 to bent axle 3.In the time that vane slot 211 sucks refrigerator oil, ball is towards the direction motion of Sealing 421, thereby the first end of oil feed line 4 and the second end cut off, being pressed into refrigerator oil in the center oilhole 31 of oily cap 7 and bent axle 3 can adverse current oil return pond 11 and vane slot 211, promote the fuel feeding efficiency of oil feed line 4, improved the reliability of the horizontal rotary compressor 100 that uses this oil feed line 4.
Certainly, the invention is not restricted to this, in another specific embodiment of the present invention, with reference to Fig. 7-Fig. 9, only at oil-sucking hole 41 places, flange is set, flange is concordant with the edge of oil-sucking hole 41, and extend towards the direction at oil feed line 4 centers from the edge of oil-sucking hole 41, in oil-absorbing process, because oil supply hole is all immersed in oil sump 11, adopt flange, fuel delivery is guaranteed; In oil extraction process, due to the impact of flange, the refrigerator oil in vane slot 211 only has can enter oil sump 11 on a small quantity, has effectively improved fuel feeding efficiency.In the most of center oilhole 31 and oily cap 7 that feeds bent axle 3 of refrigerator oil that adopts this mode fuel feeding process to suck, effectively improve fuel feeding efficiency, ensured the reliability of horizontal rotary compressor 100.
