Abstract
A compressor has a casing and a compressing member located within the casing. A gas drawn from a suction chamber into a compression chamber is compressed to be discharged to a discharge chamber in accordance with the operation of the compressing member. The compressor has a drive apparatus located within the casing for driving the compressing member. The drive apparatus has a fixed drive member fixed to the casing and having a plurality of electrode strips arranged in a single direction with a predetermined pitch. A second member is fixed to the compressing member. The compressing member is driven by relative movement generated between the fixed and movable drive members in response to Coulomb force generated between the fixed and movable drive members when voltage is applied to the electrode strips.
