<p>Made from sheet metal, a piston (7) forms a ring-shaped bowl and overlaps a ring-shaped axial shoulder (5) on-axis on a plastic casing (2) radially inside and outside. Groove-ring seals are used as seals (12,13). Radially inside and outside in the ring-shaped axial shoulder, there are ring grooves (14,15), into which the seals are inserted. A rolling bearing (16) is held on the piston.</p> |
