The procedure of calculation of profile and end clearances in working chambers of dry compression scroll machines considering thermal and force deformations of compressor parts is presented. It is shown that the thermal deformations of scroll machine parts make the determining contribution into clearance change. Force deformations are negligible due to small load of gas forces and constructive peculiarities of scroll machines connected with flexural stiffness of scrolls.
