INTERNAL FLOATING PISTON
Disclosed herein is a shock absorber comprising a cylinder, a rod, a main damping piston, the main damping piston coupled to the rod and configured for operation within the cylinder, the main damping piston configured to divide the cylinder into a compression side and a rebound side, a body cap disposed at one end of the cylinder, wherein the body cap has a second inner diameter greater than an inner diameter of the cylinder, an internal floating piston disposed within the body cap, configured to divide the body cap into a first side and a second side, and a base valve piston disposed to separate the compression side from the first side.
1 . A shock absorber comprising:
A cylinder;
a rod;
a main damping piston, the main damping piston coupled to the rod and configured for operation within the cylinder, the main damping piston configured to divide the cylinder into a compression side and a rebound side;
a body cap disposed at one end of the cylinder, wherein the body cap has a second inner diameter greater than an inner diameter of the cylinder;
an internal floating piston disposed within the body cap, configured to divide the body cap into a first side and a second side; and
a base valve piston disposed to separate the compression side from the first side.
2 . The shock absorber of claim 1 further comprising:
