Abstract
A scroll compressor having a stationary scroll member and a rotary scroll member. The compressor is provided with a mechanism for obtaining an orbital movement of the rotary scroll member while preventing a rotation thereof about its own axis. The mechanism has a stationary and a rotary ring arranged in parallel and spaced from each other. These rings form a plurality of circumferential spaced facing pairs of circular holes. The mechanism also has shoes arranged in the respective holes and balls arranged between the shoes in the facing pair of holes. The shoes can maintain a parallel location with respect to the corresponding holes, since the shoes are movable relative to the ball. A sealtight contact of the rotary scroll member with the stationary scroll member is realized over a prolonged period.
