Abstract
A control cylinder unit for varying a spring constant of a vehicular stabilizer includes a cylindrical fluid chamber divided into upper and lower liquid chambers by a slidably inserted piston. The upper and lower liquid chambers are communicated with each other through a controlled rotary valve installed in a piston rod connected to the piston. A reservoir chamber is formed around the liquid chamber and is communicated with the upper and lower liquid chambers through first and second check valves installed at upper and lower ends of the liquid chamber. The first and second check valves function to allow fluid from the reservoir chamber into the upper and lower liquid chambers. Further, a hole for communicating the liquid chamber and the reservoir chamber is formed at a center portion of a cylindrical wall of the fluid chamber.
