As shown in fig. 1,13A is corresponding with floss hole, and when vertical direction Y2 looks, the front end of the restriction 15G of discharge passage 15E is positioned at the center of back side panel 15.Clear and definite, when vertical direction Y2 looks, restriction 15G is positioned at the center of back side panel 15 on the opposite side of running shaft 17, rather than in the bottom of back side panel 15.Pass through restriction 15G throttling from emission quotas D by the refrigerant gas stream that discharge passage 15E is transported to drain chamber 30, the pressure of the refrigerant gas that must be transported to drain chamber 30 is reduced.That is, pressure is transported to drain chamber 30 less than the refrigerant gas of the pressure among the emission quotas D by restriction 15G.Thus, drain chamber 30 is as low pressure area, and its pressure is lower than the pressure among the emission quotas D, and is being positioned at emission quotas D downstream when the flow direction of refrigerant gas is looked.
Vane compressor 10 has the oil separator 40 that is arranged in drain chamber 30, is used for separating the lubricant oil that is contained in refrigerant gas.Pressure in pressure in the oil separator 40 and the drain chamber 30 about equally, therefore, the inside of oil separator 40 is same same as above-mentioned low pressure area.Drain chamber 30 is positioned at oil separator 40 outer parts and is used as accumulator 31.
Oil separator 40 has housing 41, oil separation chamber 42 and oily splitter cylinder 43.Housing 41 is installed on the thickened portion 15C of back side panel 15 by pad G, to cover discharge passage 15E.Oil separation chamber 42 is formed in the housing 41, and cylindrical.Oil splitter cylinder 43 is positioned at the top of oil separation chamber 42, and is installed on housing 41 in a fixed manner.As shown in figs. 1 and 4, housing 41 is formed with a pair of communication passage 41A, and described a pair of communication passage 41A is communicated with the upper end of corresponding discharge passage 15E, and faces the outer circumferential face of oily splitter cylinder 43.Discharge passage 15E is connected in oil separator 40 in the drain chamber 30 with emission quotas D.
The housing 41 of oil separator 40 has oil duct 41B in its underpart, the lubricant oil in the oil separation chamber 42 drops in the accumulator 31 by this oil duct 41B.In addition, the thickened portion 15C that runs through back side panel 15 is formed with oil supply gallery 15D, is used for the lubricant oil of accumulator 31 is delivered to the sliding parts of vane compressor 10, as the groove of rotor 18.
As shown in Fig. 1,3 and 4, back side panel 15 has drainback passage 45 in its underpart, and the lubricant oil among the emission quotas D turns back to drain chamber 30 by this drainback passage 45.Drainback passage 45 is provided by spill port 45B and oil-return groove 45A, and this spill port 45B extends through the thickened portion 15C of back side panel 15, and this oil-return groove 45A is formed in the ear end face of thickened portion 15C, so that be communicated with spill port 45B.
The front end of spill port 45B is close to the lower end of the front-end face 15A of back side panel 15, and opens to the bottom of emission quotas D.That is, the position that is connected at discharge passage 15E below the height at emission quotas D place of drainback passage 45 is connected in emission quotas D.Spill port 45B extends through the thickened portion 15C of back side panel 15 obliquely, makes the rear end of spill port 45B be higher than its front end, and position a little less than running shaft 17 on thickened portion 15C, the rear end of spill port 45B is open.
Oil-return groove 45A is connected in the rear end of spill port 45B in its lower end.Oil-return groove 45A tilts to extend upward, and is connected in the groove 15F of discharge passage 15E in the top.Oil-return groove 45A is communicated with groove 15F, and when the flow direction of refrigerant gas is looked, this groove 15F is positioned at the downstream of the restriction 15G of discharge passage 15E.The pad G of the ear end face of the thickened portion 15C of oil-return groove 45A by being installed on back side panel 15 and drain chamber 30 sealings separate.
Thus, emission quotas D is connected in the discharge passage 15E that is communicated with drain chamber 30 by drainback passage 45.Drainback passage 45 is positioned at the below of this discharge passage 15E and floss hole 13A.Discharge passage 15E is communicated with the communication passage 41A of oil separator 40, and therefore, emission quotas D is communicated with oil separator 40 by drainback passage 45 and discharge passage 15E.
To the operation of vane compressor 10 be described below.When running shaft 17 rotated with rotor 18 and blade 20, refrigerant gas was introduced in the pressing chamber 21 that volume increasing by intakeport 14B and air intake passage 13B from breathing space S.Along with rotor 18 is further rotated, the volume of pressing chamber 21 then reduces, so refrigerant gas is compressed in pressing chamber 21.Subsequently, refrigerant gas is discharged among the recess 13D (emission quotas D) by floss hole 13A.When refrigerant gas is discharged among the emission quotas D,, in emission quotas D, lubricant oil is isolated from refrigerant gas by for example bump of refrigerant gas on the inner peripheral surface of rear case 11.
Be discharged to refrigerant gas among the emission quotas D by the restriction throttling, and flow among the groove 15F of discharge passage 15E.Refrigerant gas flows to the oil separator 40 from discharge passage 15E by communication passage 41A.Refrigerant gas is sprayed to the outer circumferential face of oily splitter cylinder 43 in the oil separation chamber 42, centers on the outer circumferential face rotation of oily splitter cylinder 43, and is directed towards the bottom of oil separation chamber 42.Thus, by centrifugation lubricant oil and refrigerant gas are separated.Lubricant oil is collected in the oil separation chamber 42, and drops onto by oil duct 41B in the accumulator 31 of drain chamber 30.Subsequently,, lubricant oil is delivered to the sliding parts of vane compressor 10,, is used to lubricate as the groove of rotor 18 by the oil supply gallery 15D of back side panel 15.On the other hand, the refrigerant gas that lubricant oil has been separated with it moves up in oily splitter cylinder 43, and discharges vane compressor 10 outer (for example, being discharged in the external refrigerant loop of the air-conditioning that wherein is connected with vane compressor 10).
In above-mentioned vane compressor 10, isolated lubricant oil utilizes the pressure reduction between emission quotas D and the drain chamber 30 to pass through spill port 45B from refrigerant gas in emission quotas D, and flow among the oil-return groove 45A.Then, flow of lubricant and subsequently with the refrigerant gas that flows towards oil separator 40 in discharge passage 15E, is introduced in the oil separator 40 by communication passage 41A in the groove 15F of discharge passage 15E.Lubricant oil is separated with refrigerant gas in oil separator 40, and drops onto in the accumulator 31 of drain chamber 30.Thus, the drainback passage 45 that emission quotas D is connected in drain chamber 30 makes the lubricant oil that are present among the emission quotas D can turn back to drain chamber 30.
Vane compressor 10 according to first mode of execution provides following advantage.
(1) emission quotas D is positioned at the radially outer of pressing chamber 21, and drain chamber 30 is formed among the housing H.Emission quotas D links to each other by the discharge passage 15E that is formed in the back side panel 15 with drain chamber 30.Discharge passage 15E is connected in emission quotas D by the drainback passage 45 that is positioned at discharge passage 15E below.Therefore, isolated lubricant oil is back to discharge passage 15E by drainback passage 45 from refrigerant gas in emission quotas D, and turns back to drain chamber 30 with the refrigerant gas of the discharge passage 15E that flows through subsequently.Thus, drainback passage 45 is set has prevented that lubricant oil from staying among the emission quotas D, thereby the volume that has prevented emission quotas D reduces, and correspondingly cushioned the discharging fluctuation.In addition, having prevented that lubricant oil from staying among the emission quotas D becomes dead oil, thereby the lubricants capacity that has prevented to be supplied to the sliding parts of vane compressor 10 reduces, and has prevented that therefore the reliability of sliding parts from reducing.
(2) back side panel 15 is formed with the drainback passage 45 that emission quotas D is linked to each other with discharge passage 15E.Therefore, isolated lubricant oil turns back to discharge passage 15E by drainback passage 45 from refrigerant gas in emission quotas D, and further turns back to drain chamber 30 with the refrigerant gas of the discharge passage 15E that flows through.Thus owing to prevented that lubricant oil from staying among the emission quotas D, so the motion of escape cock 22 (particularly opening the motion of floss hole 13A) can not be interfered because of these lubricant oil, thereby prevented the delay of opening of emission quotas D.Therefore, prevented the excess compression of refrigerant gas, this causes the power loss in the vane compressor 10 to reduce.
(3) drainback passage 45 being set is communicated with emission quotas D and discharge passage 15E.Because refrigerant gas flows to the discharge passage 15E from emission quotas D, therefore, the lubricant oil that turns back to discharge passage 15E by drainback passage 45 further turns back to drain chamber 30 (oil separator 40) with the refrigerant gas of the discharge passage 15E that flows through.
(4) lubricant oil among the emission quotas D turns back to discharge passage 15E by drainback passage 45, and is introduced in the oil separator 40 by communication passage 41A.Therefore, when the refrigerant gas among the emission quotas D turned back to discharge passage 15E with lubricant oil by drainback passage 45, refrigerant gas and lubricant oil were separated in oil separator 40.Therefore, compare by the situation that drainback passage 45 directly turns back to accumulator 31, more effectively separated refrigerant gas and lubricant oil with the lubricant oil among the emission quotas D.
(5) cylinder body 13 has recess 13D at its outer circumferential face place, and the ladder surface 13F that each recess 13D all has attachment face 13G and intersects with this attachment face 13G, floss hole 13A are open on this attachment face 13G.In a recess 13D, ladder surface 13F is positioned at the top of attachment face 13G.In another recess 13D, ladder surface 13F is positioned at the below of attachment face 13G.In this case, lubricant oil tends to stay among the described recess 13D, rather than stays among described another recess 13D, and this causes producing pressure reduction between two recess 13D.This pressure reduction can cause the irrgular movement of rotor 18 in cylinder body 13, may cause noise.But, according to present embodiment,, the setting of drainback passage 45 stays among the emission quotas D because having prevented lubricant oil, and therefore,, also can prevent this irrgular movement of rotor 18, thereby prevent noise even recess 13D has different shapes.
(6) drainback passage 45 runs through back side panel 15 formation, and this back side panel 15 separates and limit emission quotas D and drain chamber 30 in housing H.Preventing that lubricant oil from staying among the emission quotas D can only realize by the existing parts (back side panel 15) of vane compressor 10 are simply changed.
(7) run through back side panel 15 and be formed with discharge passage 15E, refrigerant gas is discharged to the drain chamber 30 from emission quotas D by this discharge passage 15E.Because discharge passage 15E has the restriction 15G that sees the center that is positioned at back side panel 15 along vertical direction Y2, therefore, prevented that in emission quotas D isolated flow of lubricant is in discharge passage 15E from refrigerant gas.
(8) drainback passage 45 is positioned at the below of discharge passage 15E, and has the spill port 45B that front end is opened to the bottom of emission quotas D.Therefore, the lubricant oil that is stored in the bottom of emission quotas D turns back to drain chamber 30 by drainback passage 45.
(9) drainback passage 45 is connected in emission quotas D at its front end, and is connected in discharge passage 15E in its back-end, and when the flow direction of refrigerant gas is looked, this discharge passage 15E is positioned at the downstream of emission quotas D.For example, if drainback passage 45 is connected in emission quotas D and sees the pressing chamber 21 that is positioned at emission quotas D upstream along the flow direction of refrigerant gas, then the cross sectional area of drainback passage 45 need be very little, so that restriction is back to the lubricants capacity of pressing chamber 21.But, according to present embodiment, because drainback passage 45 is connected in the discharge passage 15E that is positioned at emission quotas D downstream, therefore, the lubricants capacity that turns back to drain chamber 30 (oil separator 40) need not to be restricted, thereby allows the cross sectional area of drainback passage 45 relatively large.In addition, be connected under the situation of pressing chamber 21 at aforesaid drainback passage 45, when the lubricants capacity in being present in emission quotas D is considerably less, refrigerant gas moves to the pressing chamber 21 from emission quotas D by drainback passage 45, and be compressed once more, thereby cause the compression efficiency of vane compressor 10 to reduce.But according to present embodiment, drainback passage 45 is connected in the discharge passage 15E that is positioned at emission quotas D downstream, and the recompression of refrigerant gas can not take place, and lubricant oil turns back to drain chamber 30 and can not reduce the efficient of vane compressor 10.
Above-mentioned mode of execution can following illustrational multiple mode be changed.
Fig. 5 shows another mode of execution of the drainback passage of vane compressor 10.Drainback passage 50 comprises first passage 51 that is formed in the back side panel 15 and the second channel 52 that is formed among the pad G.First passage 51 is connected in emission quotas D at the one end.Second channel 52 is connected in first passage 51 and discharge passage 15E.
As an alternative, drainback passage can run through back side panel 15 and form at the one end and be connected in emission quotas D, and is connected in bottom (accumulator 31) as the drain chamber 30 of low pressure area at its other end.In this case, the lubricant oil among the emission quotas D directly turns back to the bottom of drain chamber 30.
Drainback passage can form at the one end in the housing 41 of back side panel 15 and oil separator 40 and be connected in emission quotas D, and is directly connected in communication passage 41A as the oil separator 40 of low pressure area at its other end.
Drainback passage can form in cylinder body 13 that the one end is connected in emission quotas D in suction stroke, and its other end is connected in the pressing chamber 21 as low pressure area.In this case, drainback passage provides by the otch in the face of forming in the ear end face of back side panel 15 at cylinder body 13.
Drainback passage can be connected in emission quotas D at the one end, and is connected in air intake passage 13B or oil supply gallery 15D as low pressure area at its other end.
The lubricant oil that turns back to discharge passage 15E by drainback passage 45 can directly turn back to drain chamber 30, need not to be provided with oil separator 40.In this case, the oil-return groove 45A of drainback passage 45 is sealed by pad G.
