COMPRESSIEKLEP VOOR EEN SCHOKDEMPER.

摘要

A compression or base valve for a shock absorber including concentrically oriented pressure and reserve cylinders defining a fluid reservoir therebetween, with the pressure cylinder having a reciprocally disposed piston therein; the compression valve being located at the lower end of the pressure cylinder and adapted to selectively communicate fluid between the pressure cylinder and the fluid reservoir; the valve including a base member extending across the lower end of the pressure cylinder and defining a central opening and a plurality of circumferentially spaced passages arranged concentrically of the central opening, a first valve member mounted above the base member and adapted to selectively close the plurality of fluid passages and a second valve member carried on a relief valve reciprocally disposed below the base member, the second valve member being movable to a first position response to low fluid pressure flowing from the pressure cylinder to the fluid reservoir and being movable to a second position in response to movement of the relief valve when relatively higher pressure fluid is communicated from the pressure cylinder to the fluid reservoir.
