ROCKING CYLINDER ASSEMBLY, METHOD OF OPERATING ROCKING CYLINDER ASSEMBLY, MACHINE COMPRISING ROCKING CYLINDER ASSEMBLY, AND BEARING COMPONENT FOR ROCKING CYLINDER ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a cylinder assembly.SOLUTION: A cylinder 2 has a cylinder bore 12 terminating at a bearing surface and a cylinder aperture 16 defined by a line of intersection between the cylinder bore and the bearing surface. The cylinder is rocking rotatable between a first end position and a second end position. A rocking cylinder assembly 1 comprises a bearing component 8 that has a component bore terminating at a component bearing surface and a component aperture 22 defined by a line of intersection between the component bore and the component bearing surface. The cylinder aperture and the component apertures are fluidly communicated as the cylinder rotates between the first and second end positions. The ratio of the area of a second one of the apertures to the square of the maximum extent of the second one of apertures in a direction perpendicular to a rocking axis and perpendicular to a second principal fluid flow axis is greater than the ratio of the area of a first one of the apertures to the square of the maximum extent of the first one of the apertures in a direction perpendicular to the rocking axis and perpendicular to a first principal fluid flow axis.
