Main cylinder for hydraulic piston - has groove in casing for fixing holder by sprung tab, holder holding seal and acting as stop for second holder projecting from cylinder

摘要

The cylinder has a groove (84) in its casing (1), which is fixed in a metal holder (80) by a sprung tab. A seal (6') is held in position via this holder at its inner sealing lip (93). At the same time, movement of its outer sealing lip (94) is possible Hydraulic fluid can flow through an axial aperture (95). The holder also acts as a stop for another holder (82) projecting from the cylinder (2), thus ensuring that the piston cannot fall out. This holder may be slit round its circumference.
