Claims

[Scope of utility model registration request]

Both spiral bodies of a first scroll member having a spiral body fixed on one side of the plate and a second scroll member having a spiral body similarly fixed on one side of the plate are shifted by 180 degrees from each other, In a state in which the side walls of both spiral winding bodies are engaged and overlapped so that they are in contact with each other, the first scroll member is caused to revolve on a circular orbit to take in fluid while forming a closed space between both spiral winding bodies. , with the movement of the first scroll member,
In a fluid device that moves around the space and performs a unidirectional fluid compression action with a reduction in volume, a balance mechanism that offsets the unbalance of a non-rotating pivoting motion part and a flang part on the main shaft. 1. A fluid device characterized in that the drive center of a crank device that locks the first scroll member and the center of gravity of the first scroll member are substantially aligned.
