An apparatus for an active suspension system provides independent control of each adjustable spring rate mechanism. Ride height, spring rate, and oscillation control are achieved with the use of transducers that send signals to a controller. The controller receives the signals and responsively generates signals to adjust pressure and flow between an accumulator and the adjustable spring rate mechanism.

Apparatus for an active suspension system

A heat exchanger includes a first header and tank assembly having an inlet port and an outlet port. First and second tubes are included, each tube in fluid communication with the first header and tank assembly and with the other tube. An elastomeric baffle is disposed in the first header and tank assembly to substantially prevent fluid flow between the inlet port and the outlet port except through the first and second tubes.
