Abstract
A scroll compressor includes a non-orbiting scroll having a plurality of radially extending ribs on its rear face. The non-orbiting scroll preferably provides a separating function separating the interior of the sealed housing of the compressor into the discharge and suction pressure chambers. The ribs extend from a central portion of the base of the non-orbiting scroll to its outer peripheral surface. A circumferentially extending rib also connects the plural radially extending ribs.
Claims12
A scroll compressor comprising:
- a sealed housing;
- a first scroll member having a base and a generally spiral wrap extending from said base, a seal between said base and said housing to define a discharge pressure chamber on a first side of said base, and a suction pressure chamber on a second side of said base;
- a second scroll member having a base and a generally spiral wrap extending from said base, said wraps of said first and second scroll members interfitting to define compression chambers;
- a motor for driving said second scroll member to orbit relative to said first scroll member;
- and
- wherein said base of said first scroll member comprises a center portion and a periphery and wherein plural ribs extend to about said periphery on said first side.
The scroll compressor of claim 8 wherein said first rib extends along a path generally orthogonal to said second rib.
A scroll compressor comprising:
- a sealed housing;
- a first scroll member having a base and a generally spiral wrap extending from said base, a seal provided between said base and said housing to define a discharge pressure chamber on a first side of said base, and a suction pressure chamber on a second side of said base, said base of said first scroll member comprising a center point;
- a second scroll member having a base and a generally spiral wrap extending from said base, said wraps of said first and second scroll members interfitting to define compression chambers;
- a motor for driving said second scroll member to orbit relative to said first scroll member;
- and
- a plurality of radially extending ribs extending from a central boss, said central boss communicating said compression chambers to said discharge chamber, said radially extending ribs extending from said boss to an outer peripheral surface on said first side of said base of said first scroll member, and a circumferentially extending rib connecting said plural radially extending ribs.
