Abstract

L'invention concerne un compresseur électrique qui permet d'atteindre une durabilité et un rendement élevés avec une structure peu coûteuse appropriée à l'utilisation d'un réfrigérant à base de dioxyde de carbone. Le mouvement de rotation d'une plaque de lavage (23), qui présente un angle d'inclinaison fixe spécifique, est converti en mouvement d'oscillation d'une plaque d'oscillation (24), laquelle oscille alors que le mouvement de rotation sur son axe est restreint. Les pistons (21) sont actionnés par l'oscillation de la plaque d'oscillation (24). Le compresseur selon l'invention peut ainsi présenter une structure qui ne comporte pas de partie qui coulisse sous l'action de la rotation de la plaque de lavage (23) afin d'accroître la durabilité.
