A reciprocating machine component, such as a piston of an internal combustion engine or a compressor, is provided with bearing pads for transmitting lateral thrust to an associated guide surface, such as a cylinder or liner. The bearing pads are mounted such that they tilt during reciprocation in order to provide a wedge-shaped lubricant film between the pad and the surface. The mounting is also such as to ensure that the direction of tilt of the pads changes with the direction of reciprocation.

Tilting bearing pads for improved lubrication

A scraper ring system for removing fluid from a relatively moving cylindrical surface such as a piston rod which comprises a series of overlapping blades or leaves which are pressed against the rod surface at an acute angle either by a garter spring or when the blades are part of a continuous strip, by the natural resilience of the strip and blades. The blades are located in a housing and passages are provided for the discharge of any removed fluid.
