In addition, the oily separating mechanism section 40 of present embodiment, can not store the oil in space 32 in the container that is separated to the opposing party, but discharge from exhaust port 44 together with refrigerant gas, so possess the effect to the direction guiding of exhaust port 44 by the rotating flow of the generation of the inner peripheral surface in cylindric space 41.
Even do not form exhaust port 44 in cylindric space 41, but when the 41 interior oil in reserve of cylindric space, owing to not producing flowing of stretching from exhaust port 44 to outside, so before arriving pasta, rotating flow will disappear, or oil is rolled while arriving pasta.In addition, in order not form just performance oil separation function of exhaust port 44 in cylindric space 41, need to form the sufficient space for oil in reserve.
But, as the oily separating mechanism section 40 of present embodiment like this, oil is discharged from exhaust port 44 together with refrigerant gas, thus can be by rotating flow to exhaust port 44 guiding, and can not roll oil.
According to present embodiment, the refrigerant gas of that send, most High Temperature High Pressure in compression mechanical part 10 compression and from oily separating mechanism section 40, be directed to space 31 in a side container and discharge from discharge tube 4.Therefore, the refrigerant gas of most High Temperature High Pressure is by motor part 20, so motor part 20 can cooled dose of gas-heated, can realize the high efficiency of motor part 20.
In addition, according to present embodiment, the refrigerant gas of most High Temperature High Pressure is directed to a side the interior space 31 of container, can suppress thus the heating of the compression mechanical part 10 that in the container with the opposing party, space 32 is connected, so can suppress to suck the heating of refrigerant gas, can access the high volumetric efficiency in pressing chamber 15.
In addition, according to present embodiment, can be by by oily separating mechanism section 40 isolated oil, be expelled to space 32 in the opposing party's container together with refrigerant gas, so can be detained oil is arranged hardly in cylindric space 41.Therefore, isolated oil, the refrigerant gas that can not be rotated in cylindric space 41 blows afloat and is sent from sending mouth 43 together with refrigerant gas, can stably carry out oil and separate.And then, can not be detained oil is arranged in cylindric space 41, so can form littlely by cylindric space 41.
In addition, according to present embodiment, oil storage section 2 is disposed to oil storage side space 34, the oil in reserve not in compressing mechanism side space 33, so seal container 1 can miniaturization.In addition, according to present embodiment, the baffler 19 from 31 isolation of space in a side container by the exhaust port of compression mechanical part 10 17 is set, by inflow section 42, will baffler in 19 and cylindric space 41 be communicated with, the refrigerant gas by after compression mechanical part 10 compressions can be guided reliably thus to oily separating mechanism section 40.That is, all refrigerant gas are by oily separating mechanism section 40, so can separate expeditiously fuel-displaced from refrigerant gas.In addition, the overwhelming majority's who discharges from exhaust port 17 high temperature refrigerant gas, do not pass through the opposing party's the interior space 32 of container, and be discharged to the outside of seal container 1 from discharge tube 4, so can suppress the heating of motor part 20 or compression mechanical part 10.
