Scroll compressor including lubrication features
View Patent ↗A compressor may include a shell assembly, a first scroll member, and a second scroll member. The first scroll member may be located within the shell assembly and may include a first end plate and a first spiral wrap extending from a first side of the first end plate. The first end plate may define an oil groove extending into the first side. The second scroll member may be located within the shell assembly and supported for orbital movement relative to the first scroll member. The second scroll member may include a second end plate and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap to form compression pockets.
1. A compressor comprising:
a shell assembly;
a first scroll member located within said shell assembly and including a first end plate and a first spiral wrap extending from a first side of said first end plate, said first end plate defining a discharge passage and defining an oil groove extending into said first side; and
a second scroll member located within said shell assembly, supported for orbital movement relative to said first scroll member and including a second end plate and a second spiral wrap extending from said second end plate and meshingly engaged with said first spiral wrap to form compression pockets, said first end plate and said shell assembly cooperating to define a chamber isolated from said discharge passage and receiving a pressurized fluid to deflect said first end plate and said first spiral wrap toward said second scroll member.
2. The compressor of claim 1 , wherein said first scroll member is axially fixed relative to said shell assembly.
3. The compressor of claim 2 , wherein said first end plate defines an auxiliary passage in fluid communication with an intermediate one of said compression pockets and said chamber to provide said pressurized fluid to said chamber.
4. The compressor of claim 1 , wherein said oil groove is in communication with a pressurized oil source.
5. The compressor of claim 1 , further comprising a control valve located in a supply path of oil to said oil groove.
6. The compressor of claim 1 , further comprising an oil sump in communication with said oil groove.
7. The compressor of claim 1 , wherein said shell assembly defines an oil sump.
8. The compressor of claim 1 , wherein said oil groove is annular groove.
9. The compressor of claim 1 , wherein said oil groove lubricates an interface between said first scroll member and said second scroll member.
10. The compressor of claim 1 , further comprising an oil separator in communication with a discharge passage defined in said first scroll member, said oil separator receiving a mixture of oil and compressed gas from said discharge passage and returning the oil to the compressor.
11. A compressor comprising:
a shell assembly;
a non-orbiting scroll member located within said shell assembly and including a first end plate and a first spiral wrap extending from a first side of said first end plate, said first end plate defining a discharge passage and defining an oil groove extending into said first side; and
an orbiting scroll member located within said shell assembly and including a second end plate and a second spiral wrap extending from said second end plate and meshingly engaged with said first spiral wrap to form compression pockets, said first end plate and said shell assembly cooperating to define a chamber isolated from said discharge passage and receiving a pressurized fluid to deflect said first end plate and said first spiral wrap toward said orbiting scroll member.
12. The compressor of claim 11 , wherein said non-orbiting scroll member is axially fixed relative to said shell assembly.
13. The compressor of claim 11 , further comprising an oil separator in communication with said discharge passage defined in said non-orbiting scroll member, said oil separator receiving a mixture of oil and compressed gas from said discharge passage and returning the oil to the compressor.
