Abstract
A dual piston shock assembly is disclosed. The dual piston shock assembly includes a body with a chamber having working fluid therein. A dual piston assembly coupled with a shaft, the dual piston assembly including a compression piston, a rebound piston, and a reservoir port coupled between the compression piston and the rebound piston along an axis of the shaft. The dual piston assembly disposed in the chamber, axially movable relative to the chamber, and separating the chamber into a compression side and a rebound side. A fluid pathway internal to the shaft, the fluid pathway fluidly coupling the chamber with a reservoir via the reservoir port.
Claims19
A shock assembly comprising:
- a body comprising a chamber with a working fluid therein;
- a dual piston assembly coupled with a shaft, said dual piston assembly comprising:
- a compression piston;
- a rebound piston;
- and
- a reservoir port coupled between said compression piston and said rebound piston along an axis of said shaft;
- said dual piston assembly disposed in said chamber and axially movable relative to said chamber, said dual piston assembly separating said chamber into a compression side and a rebound side;
- a fluid pathway internal to said shaft, said fluid pathway fluidly coupling said chamber with a reservoir via said reservoir port;
- and
- a bypass flow path, said bypass flow path fluidly coupling said compression side of said chamber with said rebound side of said chamber while bypassing said dual piston assembly.
