Compressor driver

A compressor including a fixed scroll member fixed to a casing and having a base plate and a scroll element, and a movable scroll member having a base plate and a scroll element, said scroll elements being engaged with each other with a compression chamber defined between them so that said compression chamber moves toward the centers of the scroll elements from the peripheries of the scroll elements to compress a gas when said movable scroll element is directly moved along an orbital path by means of a drive apparatus which is constituted by a plurality of electrostatic actuators for applying driving forces in a plurality of different directions within parallel planes to said movable scroll member, each of said parallel planes being parallel to the base plate of said movable scroll member, each electrostatic actuator comprising:

• a fixed drive member having a plurality of first electrode strips arranged in a single direction with a predetermined pitch;
• and
• a movable drive member having a plurality of second electrode strips arranged in the same direction as said first electrode strips with said predetermined pitch, said fixed and movable drive members being located opposite to each other so that said movable drive member moves in said single direction in response to Coulomb force generated between said fixed and movable electrode strips when voltage is applied to said fixed and movable electrode strips.
