CA 2266633

A rotary hydraulic machine (10) for incorporation in a drill string (92) of a well formation (86). The machine (10) is particularly adapted to act as a motor and includes an outer housing (11) of a generally cylindrical configuration having a radial inner surface (12). Rotatably mounted within the housing (11) is a shaft assembly (13) including a shaft (14) upon which a stator (15) is mounted. The stator (15) includes a plurality of lobes (16) which have a maximum radius approximately equal to the radius of the surface (12). A plurality of gates (35) are radially movably mounted in the housing (11) and engage the stator (15). The shaft (14) is hollow to provide for the delivery and the removal of hydraulic fluid to the working chambers (45 and 46) of the machine (10).

Cette invention se rapporte à une machine hydraulique rotative (10) conçue pour être incorporée dans un train de tiges de forage (92) d'une installation de puits (86). Cette machine (10) est particulièrement conçue pour servir de moteur et elle comprend un logement externe (11) ayant une configuration généralement cylindrique avec une surface radiale interne (12). Un ensemble à arbre (13) est monté rotatif dans ce logement (11), cet ensemble comportant un arbre (14) sur lequel est monté un stator (15). Ce stator (15) comporte plusieurs lobes (16) qui ont un rayon maximum approximativement égal au rayon de la surface (12). Plusieurs portillons (35) sont montés dans le logement (11) en position radialement mobile et coopèrent avec le stator (15). L'arbre (14) est creux pour assurer l'apport de fluide hydraulique aux chambres de travail (45 et 46) de la machine (10) et pour assurer le retrait de fluide hydraulique de ces chambres.
