摘要： The invention concerns an hydraulically powered mechanism of the kind having a piston assembly which is arranged to be driven by hydraulic fluid acting on it in a working zone and an item of equipment which is to be driven by the piston assembly. The piston assembly presents a face which acts at an interface against a complemental face on the item of equipment. A fluid passage is provided to supply hydraulic fluid from the working zone to the interface for lubrication purposes. In a specific application of the invention it may be used in the rotary indexing mechanism of an hydraulically powered, typically a water-powered, rockdrill.
