- the document FR 2 885 966 describes a scroll compressor, also known by the term Scroll compressor, comprising a sealed enclosure delimited by a shell, and containing a suction volume and a compression volume respectively arranged on either side of a body contained in the enclosure.
- the shell defining the sealed enclosure comprises a refrigerant gas inlet.
- An electric motor is arranged in the sealed enclosure, with a stator located on the outer side, mounted fixed relative to the ferrule, and a rotor disposed in central position, integral with a drive shaft, crankshaft-shaped, of which a first end drives an oil pump supplying, from oil contained in a housing located in the lower part of the enclosure, a lubrication duct formed in the central part of the shaft.
- the lubrication duct has lubrication holes at different guide bearings of the drive shaft.
- the compression volume contains a compression stage comprising a fixed volute equipped with a spiral engaged in a spiral of a moving volute, the two spirals delimiting at least one compression chamber of variable volume.
- the second end of the drive shaft is equipped with an eccentric driving the moving volute in an orbital motion, to achieve the compression of the refrigerant gas sucked. From a practical point of view, refrigerant gas arrives from outside and enters the sealed enclosure. Part of the gas is sucked directly towards the compression volume, while the other part of the gas passes through the engine before flowing towards the compression stage.
- All the incoming gas is directly to the compression stage, or after passing through the engine, is sucked by the compression stage, penetrating into at least one compression chamber defined by the two spirals, the inlet is forming at the periphery of the compression stage, and the gas being conveyed towards the center of the spirals as compression occurs by decreasing the volume of the compression chambers, resulting from the movement of the mobile scroll relative to the fixed scroll.
- the gas compressed leaves in central part in the direction of the compressed gas recovery chamber.
- the refrigerant gas entering the compressor can be charged with oil, this oil can come for example leaks bearings, licking the surface of the oil sump by gas .
- oil content in the refrigerant gas changes according to the rotational speed of the rotor of the electric motor.
- the amount of circulating oil with the refrigerant gas is low, which can degrade the performance of the compressor and reduces the lubrication of the various parts of the compressor.
- US 6,287,099 discloses a variable speed scroll coiled compressor comprising a drive shaft having an oil supply conduit extending the full length thereof, the oil supply conduit being fed in oil from oil contained in an oil sump by an oil pump disposed at a first end of the drive shaft.
- the drive shaft comprises a transverse orifice, one end of which opens into the feed duct and the other end of which opens into the wall of the shaft, in an area thereof located in the volume of the shaft. suction.
- the compressor described in US Pat. No. 6,287,099 also comprises a shutter arranged to close the transverse orifice when the speed of the compressor is less than a predetermined value and to move and release, under the effect of a centrifugal force, the transverse orifice when the speed of the compressor exceeds the predetermined value.
- the shutter closes the transverse orifice.
- all of the oil entering the feed conduit is forced toward the second end of the drive shaft and injected into the compression volume.
- the shutter releases the transverse orifice.
- a portion of the oil having entered the feed pipe is discharged through the transverse orifice and is therefore not injected into the compression volume.
- the transverse orifice no longer allows to divert a sufficient amount of oil to the oil sump. This can result in a large amount of oil in the compression volume and thus an excessive oil level in the refrigerant gas leaving the compressor.
