Title
(EN) ROTARY ELEMENT AND ROTARY DISPLACEMENT DEVICE COMPRISED THEREOF
(FR) ÉLÉMENT ROTATIF ET DISPOSITIF DE DÉPLACEMENT ROTATIF CONSTITUÉ DE CE DERNIER
Abstract
(EN)
Impeller comprising a body having a plurality of lobes with a curvilinear end and disposed about a rotary axis, the body comprising a composition of a resin and fibers disposed in the resin, wherein the fibers extend axially along the rotary axis. Rotary displacement device comprising such an impeller.
(FR)
L'invention concerne une nouvelle construction pour des éléments rotatifs qui trouvent une utilisation dans des dispositifs de déplacement rotatifs, par exemple, des pompes volumétriques et des compteurs. La construction proposée peut incorporer des fibres, par exemple, des fibres de carbone, disposées dans une matrice de résine. Cette construction peut réduire le besoin d'effectuer des procédés secondaires qui sont nécessaires pour utiliser de nombreux éléments rotatifs de conception classique. De plus, des exemples des éléments rotatifs peuvent améliorer le fonctionnement des dispositifs de déplacement, par exemple, par réduction de la résonance et en permettant au dispositif de déplacement de fonctionner à une vitesse accrue.
