Abstract

For controlling motion of a movable part, a device comprises a first chamber and a second chamber in fluid communication with each other via a variable orifice that is responsive to pressure within the first chamber. Movement of the movable part is thereby at least partially controlled by flow of a fluid from the first chamber to the second chamber via the variable orifice. An increase in pressure in the first chamber may cause an increase in orifice area, whereas a decrease in pressure may cause a decrease in the orifice area. Pressure-dependent elements that change geometries and/or the pressure-based opening/closing of one or more bypass channels may be used for this purpose. Where bypass channels are used, a valve may be opened/closed based on an operating parameter of a system in which the movable part is a component. Such a system may comprise an internal combustion engine.
