Abstract: A brake apparatus and method utilize an electric power brake booster for operating a push rod actuated hydraulic master cylinder. The existing vehicle electrical system provides electric power for the power brake booster, thus eliminating the need for engine driven or auxiliary pressure/vacuum sources. The electric power brake booster includes an electrically powered actuator having an output shaft adapted for operative connection to the master cylinder, and an input for receipt of a signal indicative of force applied to the push rod. The electrically powered actuator augments the force applied to the push rod in response to the signal indicative of the force applied to the push rod. The booster may include a sensor for sensing force applied to the push rod and generating the signal indicative of the force applied to the push rod.

Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.

Abstract: A damper includes a piston that carries a relatively compact control valve for controlling fluid flow through the piston. The control valve provides a variable amount of damping by regulating damper fluid flow between the extension chamber and the compression chamber of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through a flow path as determined by the control valve. The damping force of the damper varies depending upon the loading conditions of the vehicle. The control valve is air pressure actuated to adjust the damping force and control the flow of fluid in the flow path.
