Document Type and Number:
Japanese Patent JP2710827
Kind Code:
B2
Abstract:
Here is disclosed a scroll-type fluid handling machine having a hermetically sealed casing enclosing therein a stationary side scroll member fixed to the casing, a movable side scroll member adapted to be rotatable in engagement with the stationary side scroll member and an electromotor used to drive the movable side scroll member, wherein said electromotor comprises a linear motor consisting of movable side magnets and stationary side coils mutually facing in the axial direction of the machine itself and is adapted to directly drive the movable side scroll member. Such feature makes the drive shaft as well as the crankshaft which have conventionally been essential to the machine unnecessary, thereby minimizing a mechanical loss and improving a mechanical efficiency. In addition, the axial dimension of the machine can be substantially reduced so as to obtain a compact, light weight machine.
