Title (EN) DEVICE FOR LUBRICATING A BEARING ACCEPTING A ROTARY SHAFT OF AN ELEMENT OF A CLOSED CIRCUIT OPERATING ON A RANKINE CYCLE AND METHOD USING SUCH A DEVICE
(FR) DISPOSITIF DE LUBRIFICATION D'UN PALIER RECEVANT UN ARBRE ROTATIF D'UN ÉLÉMENT D'UN CIRCUIT FERMÉ FONCTIONNANT SELON UN CYCLE DE RANKINE ET PROCÉDÉ UTILISANT UN TEL DISPOSITIF
Abstract: front page image
(EN)The present invention relates to a device for lubricating at least one bearing accepting a rotary shaft of an element of a closed circuit (10) operating on a Rankine cycle, the said circuit comprising a pump (12) for compressing/circulating fluid in liquid form, a heat exchanger (18) swept by a hot source (24) to evaporate the said fluid, means (30) of expanding the fluid into vapour form, a cooling exchanger (42) swept by a cold source (F) to condense the working fluid, a working fluid reservoir (48), pipes (50, 52, 54, 56, 58, 60) for circulating the working fluid, and a lubricating circuit (62) for lubricating the said bearing. According to the invention, the lubricating circuit comprises a lubricating pipe (64) connected to the closed circuit (10) and comprising means (66) of subcooling fluid circulating through the lubricating pipe.
(FR)La présente invention concerne un dispositif de lubrification d'au moins un palier recevant un arbre rotatif d'un élément d'un circuit fermé (10) fonctionnant selon un cycle de Rankine, ledit circuit comprenant une pompe de compression/circulation (12) du fluide sous forme liquide, un échangeur de chaleur (18) balayé par une source chaude (24) pour l'évaporation dudit fluide, des moyens de détente (30) du fluide sous forme vapeur, un échangeur de refroidissement (42) balayé par une source froide (F) pour la condensation du fluide de travail, un réservoir de fluide de travail (48), des conduites de circulation du fluide de travail (50, 52, 54, 56, 58, 60), et un circuit de lubrification (62) pour lubrifier ledit palier. Selon l'invention, le circuit de lubrification comporte une conduite de lubrification (64) raccordé au circuit fermé (10) et comprenant des moyens de sous-refroidissement (66) du fluide circulant dans la conduite de lubrification.
