SCROLL TYPE FLUID MACHINE

摘要

PROBLEM TO BE SOLVED: To suppress the change of a thrust clearance due to change of temperature to prevent the reduction of performance due to the rise of temperature and prevent the contact of a lap part with a panel board of a scroll at low temperature time. SOLUTION: This scroll type fluid machine is constituted by providing an auxiliary crank mechanism 12 between a turning scroll 5 and a fixed frame 7 to prevent rotation movement of the turning scroll 5. A spacer 16 is inserted and fixed between an outer periphery fixing part of a fixed scroll 11 and the fixed frame 7 to set height H2 of the spacer 16 to be larger than height H1 of an auxiliary crank 13. Consequently, the change of a thrust clearance due to the change of temperature is reduced. COPYRIGHT: (C)2007,JPO&INPIT
