Abstract: The present disclosure relates to a shock absorber having a pressure tube forming a pressure chamber. A piston rod is disposed within the pressure chamber. A reserve tube defines a reserve chamber adjacent the pressure tube. A rod guide assembly is concentrically disposed about the piston rod and the pressure chamber and houses a plurality of digital valves. Each one of the digital valves includes a component which is moveable between an open state and a closed state, and thus helps to control a fluid flow between the pressure chamber and the reserve chamber. An electronic control system is disposed on a printed circuit board assembly (PCBA) and controls actuation of the digital valves. At least one additional valve is associated with one of the digital valves for further controlling a flow of fluid between the pressure chamber and the reserve chamber.

Abstract: A shock absorber is disclosed which has a base valve assembly for controlling a flow of a working fluid between a reservoir chamber and a working chamber of the shock absorber. The base valve makes use of at least one digital valve assembly. The digital valve assembly communicates with an intermediate chamber formed between an intermediate tube and a pressure tube of the shock absorber. The digital valve assembly controls flow of the working fluid between the intermediate chamber and the reservoir chamber, to help control a damping action provided by the shock absorber.

Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a flux bridge portion or a flux break portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The flux bridge portion or flux break portion is axially positioned between the transverse planes.

IPC: F16F9/512
Abstract: A shock absorber includes a pressure sensitive valve assembly that controls fluid flow through the pressure sensitive valve assembly based upon the velocity of the piston assembly in the shock absorber. The pressure sensitive valve assembly restricts fluid flow as the velocity of the piston in a compression stroke increases to increase the damping loads provided by the shock absorber. A secondary valve assembly controls fluid flow through the pressure sensitive valve assembly when the pressure sensitive valve assembly is in a closed position.
