ABSTRACT:
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.
