Title (EN) ROTARY EXPANSION POWER UNIT
(FR) MOTEUR ROTATIF A EXPANSION
Abstract: front page image
(EN)A rotary expansion power unit, such as a steam engine, which has a planetating rotor (12) in a housing (11) having an epitrochoidal cavity (20). In known engines hot expansion fluid is in the interior of the rotor and surrounds the rotor journal bearing (26) This leads to excessive expansion of the rotor and requires an excessive flow of cooling oil (69) to the bearing. The invention isolates the expansion fluid (56) from the interior of the rotor by having a valve disc (49) fastened to the eccentric (25) with a first seal member (54) between the valve disc and housing end wall (15) and a second seal member (65) between the valve disc and the rotor.
(FR)Un moteur rotatif a expansion tel qu'un moteur a vapeur, qui possede un rotor planetaire (12) dans un carter (11) ayant une cavite epitrocoidale (20). Dans les moteurs connus, un fluide d'expansion thermique se trouve a l'interieur du rotor et entoure le palier du rotor (26). Ceci conduit a une expansion excessive du rotor et demande un ecoulement excessif d'huile de refroidissement (69) sur le palier. Le present dispositif isole le fluide d'expansion (56) de l'interieur du rotor a l'aide d'un disque formant vanne (49) fixe a l'excentrique (25) avec un premier organe de joint (54) entre le disque et la paroi extreme du carter (15) et un second organe de joint (65) entre le disque et le rotor.
