Patent

CA 2481950

A hydraulically operated motor may be located in an atmosphere having substantially high and varying pressure. The motor (130) may be provided with conduits (150, 158) that are in fluid communication with cavities (152) adjacent to the motor bearings (138, 140), so that fluid in the conduits may lubricate the bearings. Lubricating fluid may be introduced to the conduits across an air gap (168, 170) that is in the atmosphere having substantially high and varying pressure, and the fluid may thereby pass though and lubricate the bearings.

L'invention porte sur un moteur à fonctionnement hydraulique situé dans une atmosphère présentant une pression sensiblement élevée et variable. Le moteur est doté de conduits qui sont en communication fluidique avec des cavités adjacentes des paliers du moteur, de manière que le fluide des conduits puisse lubrifier les paliers. Le fluide lubrifiant peut être introduit dans les conduits à travers une couche d'air qui se trouve dans l'atmosphère présentant une pression sensiblement élevée et variable, le fluide pouvant par conséquent passer à travers et lubrifier les paliers.
