Patent ID: 7878776

Claim:
A scroll machine comprising: a first scroll member including a first end plate having a first spiral wrap extending therefrom; a second scroll member including a second end plate having a second spiral wrap extending therefrom, said second spiral wrap being intermeshed with said first spiral wrap such that a distal end of said first spiral wrap engages said second end plate and a distal end of said second spiral wrap engages said first end plate; a drive member for causing said scroll members to orbit relative to one another whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone; and a compensation member attached to one of said first and second scroll members and having a first reaction to a temperature change, said first reaction to said temperature change causing said one scroll member to maintain a sealed relationship between said distal end of said first spiral wrap and said second end plate and between said distal end of said second spiral wrap and said first end plate at said suction pressure zone and said discharge pressure zone.
