Abstract
In a sealed-type scroll compressor having a stationary scroll member and an orbiting scroll member, the stationary scroll member is fixed after rotating it in an orbiting direction of the orbiting scroll member by a predetermined angle from a phase angle position where a possible orbiting radius between both scroll members is made maximum at the temperature before driving the scroll compressor.
Claims2
Method for assembling a sealed-type scroll compressor having a stationary scroll member to be fixed to a frame and an orbiting scroll member to be engaged with said stationary scroll member, said method comprising the steps of:
- temporarily positioning said stationary scroll member on said frame to come into engagement with said orbiting scroll member;
- relatively positioning one of said scroll members with respect to the other scroll member in a phase angle direction of wraps of said scroll members;
- positioning said stationary scroll member with respect to said orbiting scroll member in X-direction and Y-direction of said scroll members;
- shifting one of said scroll members, which has a coefficient of thermal expansion smaller than the other scroll member, in an orbiting direction of said orbiting scroll member by a predetermined phase angle;
- and
- fixing said stationary scroll member to said frame.
