Suppose not form exhaust port 44 in cylindric space 41, oil is trapped in cylindric space 41, can not produce from exhaust port 44 and guide outside flowing into, so rotating flow will disappear before arriving pasta, or oil can be rolled-up while arriving pasta.In addition, on cylindric space 41, do not form exhaust port 44, in order to bring into play oily separation function, need to form the sufficient space of oil in reserve.
But, as the oily separating mechanism portion 40 of present embodiment, by oil is discharged from exhaust port 44 together with refrigerant gas, the exhaust port 44 that rotating flow can be led, and oil can be not rolled-up.
According to present embodiment, compressed at compression mechanical part 10, the refrigerant gas of the most High Temperature High Pressure of sending from oily separating mechanism portion 40, imports space 31 in a container and discharges from discharge tube 4.Therefore, the refrigerant gas of most High Temperature High Pressure, can not pass through motor part 20, so motor part 20 can cooled dose of gas-heated, has realized the high efficiency of motor part 20.
In addition, according to present embodiment, by space 31 in the refrigerant gas guiding to of a most High Temperature High Pressure container, can suppress thus the heating of the compression mechanical part 10 that contacts with space 32 in another container, so can suppress to suck the heating of refrigerant gas, obtain the high volumetric efficiency in pressing chamber 15.
In addition, according to present embodiment, the oil of oily separating mechanism portion 40 separation, together with refrigerant gas, is discharged to space 32 in another container, so almost do not have oil to be detained in cylindric space 41.Therefore, separated oil can not blow afloat because of the refrigerant gas of rotation in cylindric space 41, from sending mouth 43, sends together with refrigerant gas, can stablize and carry out oil separation.And, can retained oil in cylindric space 41, so cylindric space 41 can miniaturization.
In addition, according to present embodiment, store oil portion 2 is configured in store oil side space 34, can oil in reserve in compressing mechanism side space 33, so seal container 1 can miniaturization.In addition, according to present embodiment, configuration is the baffler 19 from 31 isolation of space in a container by the exhaust port of compression mechanical part 10 17, by inflow portion 42, be communicated with in baffler 19 and cylindric space 41, thus, the refrigerant gas after compression mechanical part 10 is compressed can import oily separating mechanism portion 40 reliably.That is, all refrigerant gas can be by oily separating mechanism portion 40, so can be from refrigerant gas separating oil effectively.In addition, the refrigerant gas of the most high temperature of discharging from exhaust port 17, can be by space 32 in another container, and from discharge tube 4, is discharged to the outside of seal container 1, so can suppress motor part 20 or compression mechanical part 10 is heated.
In addition, according to present embodiment, by cylindric space 41, be formed at fixed scroll 12 and main bearing parts 11, can form the path of flowing through of the refrigerant gas from exhaust port 17 to discharge tube 4 shortlyer, can make seal container 1 miniaturization.
Fig. 3 is the planimetric map of the oily separating mechanism portion of embodiments of the present invention 1, is the figure that the direction from sending mouthful is seen.The basic structure of present embodiment is identical with the disclosed structure of Fig. 1, so description thereof is omitted.In addition, the structure identical with the structure of Fig. 1 and Fig. 2 explanation paid with prosign, clipped explanation.

In present embodiment, in a container, space 31 disposes the refrigerant gas rotary component 48 that forms cylindric space 41.Refrigerant gas rotary component 48, is arranged on the outer circumferential face of baffler 19.At refrigerant gas rotary component 48, be formed with the 42b of inflow portion, send a mouthful 43b, exhaust port 44b.
The 42b of inflow portion, is communicated with in baffler 19 and cylindric space 41, sends a mouthful 43b and is communicated with space 31 in cylindric space 41 and a container, and exhaust port 44b is communicated with space 31 in cylindric space 41 and a container.The opening of the 42b of inflow portion, is formed at the distolateral inner peripheral surface in cylindric space 41.And the 42b of inflow portion, makes the refrigerant gas of discharging from compression mechanical part 10 flow into cylindric space 41 in baffler 19.The 42b of inflow portion is with respect to cylindric space 41, at tangent direction opening.
Send mouthful 43b and be formed at the distolateral of cylindric space 41, be at least formed at more distolateral by one than the 42b of inflow portion.Send a mouthful 43b, be preferably formed in one of cylindric space 41 distolateral end face.And, send a mouthful 43b, from cylindric space 41 to a container in space 31, send the refrigerant gas after separating oil.
The effect of the oily separating mechanism portion 40 of present embodiment is described below.Be discharged to the refrigerant gas in baffler 19, through being formed at the 42b of inflow portion of the upper surface of baffler 19, import cylindric space 41.The 42b of inflow portion is with respect to cylindric space 41, and at tangent direction opening, so the refrigerant gas of sending from the 42b of inflow portion is mobile along the internal face in cylindric space 41, the inner peripheral surface in cylindric space 41 produces rotating flow.This rotating flow, becomes flowing of going to exhaust port 44b.In refrigerant gas, be included in the oil of compression mechanical part 10 fuel feeding, during refrigerant gas rotation, the inwall in oil cylindric space 41 because centrifugal force is attached to that proportion is high, separated with refrigerant gas.
The rotating flow that inner peripheral surface in cylindric space 41 produces after arriving exhaust port 44b, or is turned back near exhaust port 44b, becomes by the adverse current at 41 center, cylindric space.Due to the refrigerant gas after centrifugal force separate oil, because arriving, the stream by 41 center, cylindric space sends a mouthful 43b, pass out to space 31 in a container.Pass out to the refrigerant gas in space 31 in a container, from being arranged at the discharge tube 4 in space 31 in a container, pass out to the outside of seal container 1, be supplied to refrigeration cycle.
In addition, at the separated oil in cylindric space 41, because deadweight secund flows down, exhaust port 44b is formed at the bottom of opposite side end face or the bottom in cylindric space 41, so easily discharge oil.Oil after separation, with together with a small amount of refrigerant gas, passes out to the upper surface of baffler 19 from exhaust port 44b.Pass out to the oil of baffler 19 upper surfaces, because the gap of compression mechanical part 10 is passed through in deadweight, from space 31 in a container, arrive compressing mechanism side spaces 33, and then via the wall of seal container 1 or the access of motor part 20, arrive store oil portion 2.The refrigerant gas of sending from exhaust port 44b, passes out to the outside of seal container 1 from being arranged at the discharge tube 4 in space 31 in a container, be supplied to refrigeration cycle.
The oily separating mechanism portion 40 of present embodiment, sends mouthful 43b and is formed at than the 42b of inflow portion more distolateral by cylindric space 41, and exhaust port 44b is formed at more distolateral by another of cylindric space 41 than the 42b of inflow portion.Therefore, from the 42b of inflow portion to exhaust port 44b, the inner peripheral surface in cylindric space 41 produces rotating flow, and from exhaust port 44b to sending mouthful 43b, the central part in cylindric space 41 produces and the reciprocal stream of rotating flow.Therefore,, along with exhaust port 44b leaves from the 42b of inflow portion, the number of revolution of refrigerant gas increases, and has improved oily separating effect.In addition, postrotational refrigerant gas, by the central part of rotating flow, so be positioned at than the 42b of inflow portion more by exhaust port opposition side as long as send a mouthful 43b.That is,, by making the distance of the 42b of inflow portion and exhaust port 44b large as much as possible, can improve the effect of oily rotating separation.
In addition, the oily separating mechanism portion 40 of present embodiment, is not stored in the oil after 41 separation of cylindric space, and oil is discharged from exhaust port 44b together with refrigerant gas, so the rotating flow that the inner peripheral surface in cylindric space 41 produces, has the effect of the direction of guiding exhaust port 44b.
Suppose not form exhaust port 44b in cylindric space 41, oil is trapped in cylindric space 41, can not produce from exhaust port 44b and guide outside stream into, and rotating flow can be rolled oil.In addition, in cylindric space 41, do not form exhaust port 44b, in order to bring into play oily separation function, need to form the sufficient space of oil in reserve.But, as the oily separating mechanism portion 40 of present embodiment, by oil is discharged from exhaust port 44b together with refrigerant gas, the exhaust port 44b that rotating flow can be led, and oil can be not rolled-up.
According to present embodiment, can not change compressor axle direction size be rotated separation.In addition, the number of revolution of refrigerant gas increases, so can increase cylindric space 41, in more detail, can increase the distance of the 42b of inflow portion and exhaust port 44b.Thus, can maintain compressor itself size in the inside of seal container 1, there is oily separating mechanism portion 40, and can improve oily rotating separation effect.
In addition, according to present embodiment, by the refrigerant gas rotary component 48 that forms cylindric space 41 is configured in to space 31 in a container, can shorten the path that the refrigerant gas from exhaust port 17 to discharge tube 4 flows through, seal container 1 can miniaturization.
According to present embodiment, the refrigerant gas of High Temperature High Pressure compressed at compression mechanical part 10, that send from oily separating mechanism portion 40, space 31 in the container that leads, discharges from discharge tube 4.Therefore, the refrigerant gas of High Temperature High Pressure, by mechanism portion 20, so motor part 20 can, because refrigerant gas is heated, not realize the high efficiency of motor part 20.
In addition, according to present embodiment, by space 31 in a container that the refrigerant gas of High Temperature High Pressure is led, can suppress the heating of the compression mechanical part 10 that is connected with space 32 in another container, so can suppress to suck the heating of refrigerant gas, can obtain high volumetric efficiency in pressing chamber 15.
In addition, according to present embodiment, the oil after 40 separation of oily separating mechanism portion is discharged to space 31 in a container together with refrigerant gas, so almost do not have oil to be detained in cylindric space 41.Therefore, the oil after separation, can not blown afloat cylindric space 41 is interior because of the refrigerant gas of rotation, from sending a mouthful 43b, is sent together with refrigerant gas, can carry out stable oil separated.And, can retained oil in cylindric space 41, so cylindric space 41 can miniaturization.In addition, according to present embodiment, store oil portion 2 is configured in store oil side space 34, can oil in reserve in compressing mechanism side space 33, so seal container 1 can miniaturization.
In addition, according to present embodiment, dispose the baffler 19 from 31 isolation of space in a container by the exhaust port of compression mechanical part 10 17, by the 42b of inflow portion, be communicated with in baffler 19 and cylindric space 41, thus, at the compressed refrigerant gas of compression mechanical part 10, can import reliably oily separating mechanism portion 40.That is, all refrigerant gas can be by oily separating mechanism portion 40, so can be from refrigerant gas separating oil effectively.In addition, the high temperature refrigerant gas of discharging from exhaust port 17, can, by space 32 in another container, not be discharged to the outside of seal container 1, so can suppress the heating of motor part 20, compression mechanical part 10 from discharge tube 4.
Compressor in the respective embodiments described above, also can arrange 2 above cylindric spaces 41.
In addition, the compressor of the respective embodiments described above, can use carbon dioxide as refrigeration agent.Carbon dioxide is high temperature refrigerant, in the situation that use such high temperature refrigerant, the present invention is more effective.In addition,, in the situation that using carbon dioxide as refrigeration agent, as oil, preferably use the oil (PAG) that PAG is main component.The difficult soluble oil of PAG, can not merge with carbon dioxide coolant, with the state being separated from each other, mixes and exists.Therefore, to cylindric space 41, import refrigerant gas and PAG, the PAG high with respect to refrigerant gas proportion has large centrifugal force.As a result of, PAG disperses to peripheral direction, is attached to the inwall in cylindric space 41, can be separated with refrigerant gas.That is, with respect to slightly solubility oil (or non-intermiscibility oil), more remarkable effect of the present invention.
