Abstract

A compressor may include a compression mechanism, a driveshaft, and an oil allocation member. The driveshaft drives the compression mechanism and includes a lubricant passage having an inlet and first and second outlets. The first outlet is disposed vertically higher than the inlet and the second outlet is disposed vertically higher than the first outlet. The oil allocation member is disposed within the lubricant passage. The oil allocation member may define first, second and third channels. The first channel extends through a lower axial end of the oil allocation member. The second channel receives a first portion of the lubricant from the first channel. The third channel receives a second portion of the lubricant from the first channel. The first and second portions of the lubricant may be separated from each other at a location that is vertically higher than the first outlet.

Claims (41)

1. A compressor comprising:

a compression mechanism;

a driveshaft drivingly engaging the compression mechanism and including a lubricant passage, wherein the lubricant passage includes an inlet, a first outlet, and a second outlet, and wherein the inlet and the first and second outlets are spaced apart from each other in a direction parallel to a rotational axis of the driveshaft such that the first outlet is disposed vertically higher than the inlet and the second outlet is disposed vertically higher than the first outlet; and

an oil allocation member disposed within the lubricant passage and fixed relative to the driveshaft,

wherein:

the oil allocation member includes a lower body portion and an upper body portion and defines a first channel, a second channel, and a third channel,

the first channel extends through a lower axial end of the oil allocation member and receives lubricant flowing upward from the inlet of the lubricant passage,

the second channel receives a first portion of the lubricant from the first channel through an inlet of the second channel,

the third channel receives a second portion of the lubricant from the first channel through an inlet of the third channel,

the inlets of the second and third channels are disposed vertically higher than the first outlet, and

the lower body portion of the oil allocation member separates the first channel from the first outlet of the lubricant passage.

2. The compressor of claim 1 , wherein the inlets of the second and third channels are disposed between the first and second outlets in the direction parallel to a rotational axis of the driveshaft.

3. The compressor of claim 1 , wherein the first portion of the lubricant and the second portion of the lubricant are separated from each other at a location that is vertically higher than the first outlet.

4. The compressor of claim 3 , wherein the location at which the first portion of the lubricant and the second portion of the lubricant are separated from each other is vertically lower than the second outlet.

5. The compressor of claim 1 , wherein the oil allocation member includes a divider wall that separates the inlet of the second channel from the inlet of the third channel and restricts fluid communication between the second and third channels.

6. The compressor of claim 1 , wherein the third channel extends through an upper axial end of the upper body portion.

7. The compressor of claim 1 , wherein the first outlet of the lubricant passage extends radially outward through an outer circumferential surface of the driveshaft.

8. The compressor of claim 7 , further comprising a bearing rotatably supporting the driveshaft, wherein the first outlet of the lubricant passage is aligned with the bearing to provide lubricant to the bearing.

9. The compressor of claim 7 , wherein the second outlet of the lubricant passage extends through an upper axial end of the driveshaft.

10. The compressor of claim 9 , wherein the upper axial end of the driveshaft is disposed within a hub of a scroll member of the compression mechanism.

11. The compressor of claim 1 , wherein the compression mechanism is a scroll compression mechanism including a first scroll member and a second scroll member.

12. The compressor of claim 1 , wherein the lubricant passage is an eccentric lubricant passage, and wherein the driveshaft further comprises a concentric lubricant passage that extends through a lower axial end of the driveshaft and is in fluid communication with the eccentric lubricant passage.

13. A compressor comprising:

a compression mechanism;

a driveshaft drivingly engaging the compression mechanism and including a lubricant passage, wherein the lubricant passage includes an inlet, a first outlet, and a second outlet, and wherein the inlet and the first and second outlets are spaced apart from each other in a direction parallel to a rotational axis of the driveshaft such that the first outlet is disposed vertically higher than the inlet and the second outlet is disposed vertically higher than the first outlet; and

an oil allocation member disposed within the lubricant passage and fixed relative to the driveshaft, the oil allocation member defining a first channel, a second channel, and a third channel,

wherein:

the first channel extends through a lower axial end of the oil allocation member and receives lubricant flowing upward from the inlet of the lubricant passage,

the second channel receives a first portion of the lubricant from the first channel through an inlet of the second channel and provides the first portion of the lubricant to the first outlet of the lubricant passage,

the third channel receives a second portion of the lubricant from the first channel through an inlet of the third channel and provides the second portion of the lubricant to the second outlet of the lubricant passage, and

the first portion of the lubricant and the second portion of the lubricant are separated from each other at a location that is vertically higher than the first outlet.

14. The compressor of claim 13 , wherein the location at which the first portion of the lubricant and the second portion of the lubricant are separated from each other is vertically lower than the second outlet.

15. The compressor of claim 13 , wherein a lower body portion of the oil allocation member separates the first channel from the first outlet of the lubricant passage.

16. The compressor of claim 13 , wherein the oil allocation member includes a divider wall that separates the inlet of the second channel from the inlet of the third channel and restricts fluid communication between the second and third channels.

17. The compressor of claim 13 , wherein the third channel extends through an upper axial end of the oil allocation member.

18. The compressor of claim 17 , wherein the first outlet of the lubricant passage extends radially outward through an outer circumferential surface of the driveshaft.

19. The compressor of claim 18 , further comprising a bearing rotatably supporting the driveshaft, wherein the first outlet of the lubricant passage is aligned with the bearing to provide lubricant to the bearing.

20. The compressor of claim 19 , wherein the second outlet of the lubricant passage extends through an upper axial end of the driveshaft.

21. The compressor of claim 20 , wherein the upper axial end of the driveshaft is disposed within a hub of a scroll member of the compression mechanism.

22. The compressor of claim 13 , wherein the compression mechanism is a scroll compression mechanism including a first scroll member and a second scroll member.

23. The compressor of claim 13 , wherein the lubricant passage is an eccentric lubricant passage, and wherein the driveshaft further comprises a concentric lubricant passage that extends through a lower axial end of the driveshaft and is in fluid communication with the eccentric lubricant passage.
