Abstract

A vehicle damper comprising a cylinder and a piston; a working fluid within the cylinder; a reservoir in fluid communication with the working fluid to receive working fluid from the cylinder in a compression stroke; and a remotely-operable valve, the valve operable to permit and restrict flow of the working fluid between the cylinder and the reservoir.

Claims

1. A vehicle damper comprising:

a cylinder and a piston;

a working fluid within the cylinder;

a reservoir in fluid communication with the working fluid, the reservoir operable to receive working fluid from the cylinder in a compression stroke; and

a remotely-operable valve, the valve operable to permit and restrict flow of the working fluid between the cylinder and the reservoir.
