Title
(EN) HYPOCYCLOID COMPRESSOR
(FR) COMPRESSEUR HYPOCYCLOÏDE
Abstract
(EN)
A compressor includes a stationary housing (58) disposed about a central axis (86) and having a radially inner surface defining a plurality of circumferentially spaced cavities (90) opening into an interior space (92) of the housing. The compressor further includes a plurality of fluid volume control members (80), each of which is disposed within one of the plurality of cavities and defines a fluid chamber within the cavity sealed relative to the interior space. An eccentric shaft (72) is disposed within the interior space (92) of the housing (58) and configured for rotation about the central axis (86). A hypocycloid rotor (76) is disposed within the interior space of the housing and supported on the eccentric shaft. The rotor (76) defines a plurality of lobes (104) configured for movement into and out of each cavity (90) responsive to rotation of the shaft (72)to displace the fluid volume control member (80) in each cavity (90) and adjust a volume of each fluid chamber (94).
(FR)
La présente invention concerne un compresseur comprenant un logement fixe (58) disposé autour d'un axe central (86) et ayant une surface radialement interne définissant une pluralité de cavités espacées de manière circonférentielle (90) s'ouvrant dans un espace intérieur (92) du logement. Le compresseur comprend en outre une pluralité d'éléments de régulation de volume de fluide (80), chacun étant disposé à l'intérieur d'une cavité de la pluralité de cavités et définissant une chambre de fluide à l'intérieur de la cavité étanche par rapport à l'espace intérieur. Un arbre excentrique (72) est disposé à l'intérieur de l'espace intérieur (92) du logement (58) et est conçu pour se mettre en rotation autour de l'axe central (86). Un rotor hypocycloïde (76) est disposé à l'intérieur de l'espace intérieur du logement et supporté sur l'arbre excentrique. Le rotor (76) définit une pluralité de lobes (104) conçus pour un mouvement entrant dans chaque cavité (90) et sortant de celle-ci en réponse à la rotation de l'arbre (72) pour déplacer l'élément de régulation de volume de fluide (80) dans chaque cavité (90) et ajuster un volume de chaque chambre de fluide (94).
