the scroll machine has a first and a second scroll member each having intermeshed scroll wraps . a compensation member is attached to one of the scrolls . as the scroll machine warms to operating temperature , the compensation member exerts a force on the one scroll member causing it to deflect . the deflection of the scroll member compensates for the unequal growth of the scroll wrap which is caused by a temperature difference between the radially inner section and the radially outer section of the scroll wrap .
