PISTON ASSEMBLY OF A RADIAL-PISTON HYDRAULIC ENGINE

摘要

The invention refers to a piston assembly of a radial-piston hydraulic engine whose main feature is the position of the rolling cylinder (2) in the piston head. This means that the one section of the rolling area of the rolling cylinder (2) that lies the closest to the working surface (8) of the piston always lies in the region between the working surface (8) and the radially-inwards running step (7) which divides the head (4) of the piston (1) from the guiding section (5).
