Abstract (en)
The retractable vane (15) is intended for sliding in the longitudinal notches (6) of the rotor (1) of a rotary fluid-pressure machine. The vane (15) has a substantially symmetrical lateral profile in relation to its longitudinal axis (16), particularly as regards the indentations (13) and (17). There are also lubricating reservoirs (18) which ensure permanent communication between the indentations (13) and (17). The invention is used for eliminating jamming between the members of the rotary machine, whilst at the same time ensuring perfect internal sealing. <IMAGE>
Abstract (fr)
La présente invention concerne une cloison escamotable (15) destinée à coulisser dans les encoches longitudinales (6) du rotor (1) d'une machine tournante à fluide sous pression. La cloison (15) a un profil latéral globalement symétrique par rapport à son axe longitudinal (16), notamment en ce qui concerne les échancrures (13) et (17). De plus, on prévoit des bassins de lubrification (18) qui assurent en permanence la communication entre les échancrures (13) et (17). Application: suppression du coincement entre les organes de la machine tournante, tout en assurant une parfaite étanchéité interne.
