Abstract: A smart damping control valve having a failsafe mode is provided. The control valve includes a movable valve assembly within a valve housing. The moveable valve assembly includes a shuttle valve concentrically positioned with respect to a spool valve, with the spool valve and the shuttle valve each being axially moveable within a bore in the valve housing. The control valve includes a solenoid assembly having an electromagnetically actuated armature that varies the opening pressure of the movable valve assembly. At a first electrical current, the valve assembly provides a first opening pressure, and at a second electrical current, the valve assembly provides a second opening pressure. The valve assembly provides a third opening pressure, between the first and second opening pressures, in the absence of an electrical current to the solenoid assembly.
Abstract: A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.
