Definitions
- Separator device for separating a fluid, in particular a lubricant from a coolant fluid
- the invention relates to a separator for separating a fluid, in particular a lubricant from a coolant fluid, which comprises a separating cylinder and a separating tube arranged coaxially therein.
- the separation cylinder has at least one inlet for the coolant fluid
- Cooling circuits of, for example, refrigerators or air conditioners typically include compressors for compressing a refrigerant whose mechanical components must be lubricated during operation by means of a lubricant. This causes that in the compressor
- the lubricant is usually contained in the form of an oil mist and thus forms a coolant fluid with the coolant. It is understood that the remaining components of the cooling circuit may not be contaminated with lubricant, so that the separator on the compressor typically separator or oil separator are provided for separating the lubricant contained in the coolant fluid.
- Separating cylinder is provided, which is typically part of a
- Compressor housing is.
- Such Separatorvoriquesen have an outlet for the largely freed from the lubricant coolant and another outlet, which with a reservoir for lubricant or oil
- Coolant fluid introduced through an inlet in the separation cylinder.
- the Coolant fluid circulates within the separation cylinder around the separation tube, with centrifugal forces acting on the components of the flow
- Lubricant due to its higher mass first on an inner wall of the separating cylinder or the separating tube and flows downwards, whereas the gaseous refrigerant can escape through the separating tube in the opposite direction.
- the escaping from the separation tube coolant is supplied to the other components of the cooling circuit. The secluded
- Lubricant flows into the sump and thus can be recycled to lubricate the mechanical components of the compressor.
- the published patent application DE 10 2008 013 784 AI shows a compressor with an oil separator for separating oil from a coolant.
- the oil separator comprises a separating cylinder with inlet and outlet openings. Within the separation cylinder, a separation tube is used. In the upper part of the separation cylinder, an outlet for the coolant is provided, which is supplied to the coolant circuit after the lubricant or the oil has been removed. The lubricant or oil is fed via the lower part of the separating cylinder to a storage container.
- a separation cylinder having an inlet region having at least one inlet for the coolant and an axially spaced outlet region for the separated fluid
- a separation tube arranged coaxially in the separation cylinder, which extends at least over the inlet region of the separation cylinder such that the separation tube is spaced from the separation cylinder in the inlet region in the radial direction.
- a spring-loaded closure element is arranged in the inlet region, which is designed to automatically regulate the flow velocity of the volume flow of the coolant aerosol flowing through the at least one inlet.
- the invention is based on the observation that the degree of deposition depends significantly on the flow velocity of the coolant fluid within the separation cylinder. This flow rate depends on the volume flow entering the separator device and thus on the speed of the compressor. If this varies, the flow velocity of the coolant fluid at the separation tube changes accordingly, whereby the deposition process can be adversely affected. It is therefore desirable that
- the effective passage cross section of the at least one inlet can be changed by means of the spring-loaded closure element.
- the change in the effective passage cross section takes place automatically as a function of the inlet pressure prevailing at the inlet.
- a complex, possibly electronic components requiring control and / or regulation is not necessary for this purpose.
- the closure element is able to automatically regulate the deposition process within the separating cylinder in such a way that the
- Flow rate of the coolant fluid in the separator is maintained at least approximately at a constant high level even at a varying speed of the compressor. This is accomplished by limiting the effective passage area of the inlet from the closure element at low pressures, whereas at higher inlet pressures Closing element automatically opens further. This causes a change in the volume flow flowing through the inlet such that the
- a fluid in the sense of the present specification can be both a gas or a liquid.
- the coolant used is preferably carbon dioxide (CO 2 ).
- the coolant fluid may be, for example, an aerosol that includes components of the coolant and the lubricant. In other applications, the lubricant is completely or partially dissolved in the coolant fluid.
- the spring-loaded closure element regulates the cross-sectional area of the inlet and thus the flow velocity of the inlet
- Closure element need not necessarily be designed to completely close the inlet. It is essential that by means of the closure element of the incoming volume flow regulating flow passage in
- the at least one inlet is thus automatically at least partially opened or closed again depending on the inlet pressure, which varies with the rotational speed of the compressor.
- the prevailing within the separation cylinder flow conditions are characterized almost independent of the inlet pressure and the speed of the
- Closing element designed such that the at least one inlet can be completely closed. If the inlet pressure falls below a predetermined substantially by the spring characteristic of the spring-loaded closure element Threshold, so no coolant fluid flows through the inlet into the separator. The flow rate of the coolant fluid flow within the separator device is therefore always above a minimum value in order to ensure a sufficient separation of coolant and lubricant.
- the spring-loaded closure element may comprise a multi-part construction with closure and spring elements.
- the spring-loaded closure element is designed as a bent leaf spring.
- a one-piece design of a resilient closure element is thus given.
- the leaf spring has a radius of curvature which is smaller than half the inner diameter of the separating cylinder.
- the leaf spring is preferably inserted into the separating cylinder such that the effective
- Passage cross section of the at least one inlet on the inside of the leaf spring can be limited.
- Leaf spring variable.
- the position of the leaf spring relative to the opening is determined by the pressure of the incoming fluid acting on the leaf spring.
- the adjustability is influenced by the degree of stiffness of the leaf spring.
- the preferred spring stiffness is in a range that a deflection of 0, 1 to 5 bar / mm is achieved.
- the leaf spring is formed spirally.
- the radius of curvature can be adjusted to the degree of regulation of the inlets and the number of inlets.
- the radius of curvature of the leaf spring for example, progressive
- Spring characteristic lines are formed, which can be used in particular to suitably regulate the flow behavior within the separator at particularly high and / or low inlet pressures.
- Closure element has the further advantage that effectively effective flow channels are defined, which deflect the entering volume flow in the tangential direction. This has the consequence that the tangential component of
- the at least one inlet has a guide channel which extends at least in sections in a direction deviating from the radial direction, so that the volume flow in the
- a plurality of circumferentially arranged around the separating cylinder inlets are preferably provided. Through several inlets can be the
- the inlets are arranged in a direction perpendicular to the axial direction of the row. This promotes the inflow of the volume flow in the tangential direction in the separation cylinder.
- the entirety of the inlets can preferably be closed on the inside by the spring-loaded closure element.
- the invention further relates to a compressor, such as a compressor of an air conditioner, in particular of a motor vehicle, with such
- a separator assembly which provides the associated advantages directly from the above description, in particular, a sufficiently good separation of the lubricant can be ensured even at variable speed of the compressor.
- the compressor is designed such that the separator can be arranged as a separate unit within a compressor housing and detachably connectable with this.
- the separator device forms a separate module which can be inserted into the compressor. This simplifies the function test or maintenance of the separator device or the compressor in a particularly advantageous manner.

- Housing cover 2 is part of a compressor 20, which is within a
- Coolant circuit for compressing a coolant fluid containing lubricant and coolant.
- the coolant fluid is in at least one
- Lubricant In another application, especially when carbon dioxide (C0 2 ) is provided as a coolant, the lubricant may also be at least partially dissolved in the coolant.
- the lubricant is usually oil, which is intended to lubricate the mechanical parts of the compressor continuously.
- the oil is usually introduced in the form of a mist in the coolant fluid.
- the separator device 1 comprises a separating cylinder 6 with several
- Compressor 20 stand.
- the coolant fluid flows from the compressor via the inlets 4 into an inlet region 5 of the separator device 1.
- Separating cylinder 6 is within a hollow cylindrical portion 13 of the
- Housing cover 2 for example, arranged by means of a clearance fit.
- the separator device 1 inserted into the hollow-cylindrical section 13 can be removed as a separate module, in particular for maintenance or repair purposes; for this purpose, it is necessary at most to release a reversible connection, such as, in particular, a screw connection.
- the housing cover 2 further comprises an outlet region 3 which communicates via a collection basin connection 9 with a collection basin (not shown) for collecting separated fluid.
- the section 13 is in operative connection with a not shown cooling circuit.
- this may be the refrigeration cycle of a refrigerator or an air conditioner.
- the lubricant or the oil must first be separated.
- a separation pipe 7 is arranged coaxially, which has a
- Tube section 10 of reduced diameter which extends in the direction of the outlet 3.
- a separating pipe section 14 is arranged, which has a larger cross section than the pipe section 10.
- the diameter of the pipe section 10 is about half of the separating cylinder 6.
- the separating pipe section 14 has an overall cross section on, which is roughly the cross section of the
- Separating cylinder 6 corresponds in this area.
- the pipe section 10 of reduced diameter extends over the inlet portion 5, so that the separation cylinder 6 and the separation pipe 7 in this area in the radial direction
- a plurality of inlets 4 can be arranged on the separating cylinder 6.
- the inlets 4 are arranged in the exemplary embodiment shown in a direction perpendicular to the axis AI series.
- FIG. 3A The position of the sectional plane HIB shown in FIG. 3B and the position of the sectional plane IV shown in FIG. 4 can be seen in FIG. 3A.
- FIG. 2, FIGS. 3A to 3C and FIG. 5 show a closure element 8 according to one exemplary embodiment.
- the closure element 8 comprises a spring element, which is designed as a leaf spring 11.
- the leaf spring 11 has in this
- Embodiment a radius of curvature which is smaller than half of the inner diameter of the separating cylinder 6.
- the radius of curvature of the leaf spring 11 varies slightly, so that the leaf spring 11 in the inlet region 5 of
- Separating cylinder 6 define flow channels for the inflowing coolant fluid, which favor a circulation of the coolant fluid in the tangential direction around the separation pipe 7.
- the closure element 8 is arranged inside the separating cylinder 6 around the separating tube 7, in particular in the region of the tube section 10.
- the leaf spring 11 is arranged so that it or the inlets 4 depending on the inlet pressure partly, completely or not at all occluding a penetrating volumetric flow.
- the coolant fluid is introduced as a volume flow via the inlet region 5 into the separator device 1.
- the inlet pressure generated by the compressor exerts a force on the spring element or on the leaf spring 11 of the
- Spring stiffness can be set in a range of 0, 1 to 5 bar / mm. This effective passage cross-section, which is dependent on the inlet pressure, determines with which flow rate the coolant fluid flows into the separating cylinder 6. The deposition process is thus regulated via the flow velocity of the volume flow.
- the inlets 4 and their guide channels 15 of the leaf spring 11 at least partially closed inside and open and thus regulate the inlet of the coolant fluid flow such that a constant high flow velocity of the coolant fluid within the separation cylinder 6 regardless of the speed of the Compressor is present.
- This is made possible by the variation of the passage cross section of the inlets 4 by means of the leaf spring 11, to which the continuously flowing volume flow exerts a force.
- the closure element 8 therefore provides an entering

- Volumetric flow flows essentially in the tangential direction in the separation cylinder.
- pressure relief valve 25 may be provided, which is arranged between the separating cylinder 6 and the reservoir for the oil. Due to the prevailing pressure during the deposition, the pressure relief valve 25 is usually open to drain the oil. Since no pressure difference is present during non-operation, or at standstill of the device, the pressure relief valve 25 is closed, thus preventing the return flow of the coolant fluid in the
