Abstract: A shock absorber includes a housing, a piston slidable in the housing, a piston rod extending outwardly from the piston, a cup-shaped stop cap secured to the free end of the piston rod, and an adjusting ring which protrudes from the end of the housing and can be rotated to adjust the damping coefficient by adjusting the open cross-section of throttle openings through which a hydraulic fluid is displaced by the piston. When a load pushes against the stop cap, the maximum travel is limited by the stop cap bearing directly against a rigid end ring of the housing. The load forces are introduced directly from the stop cap into the housing, without applying any loads onto the adjusting ring or other components. The adjusting ring and a return spring coaxially on the piston rod are accommodated within the stop cap in the fully retracted position.

Abstract: A filter cartridge which removes particulate contaminants from liquids includes an annular filter element which, for example, may be a pleated paper filter element, as well as an array of fins which impart a spiral motion to the liquid prior to the liquid passing through the filter element. The spiral motion imparts a centrifugal force to the particulate contaminants causing heavier filter contaminants to move away from the filter media to proximity with the wall of a housing enclosing the filter media and to subsequently accumulate in an axial space disposed beneath the filter media. Since the filter media does not need to remove particles already precipitated out of the liquid, the life of the filter media is extended, the capacity of the filter media is increased, and the distribution of contaminant particles over the upstream side of the filter media is made more uniform.
