Abstract

A hydraulic valve includes two ports, a chamber within the valve housing which, in operation, is at least partially filled with a hydraulic fluid, and a fluid switch within the chamber. The fluid switch is movable between at least a first position and a second position. In the first position, the ports are fluidly coupled to each other. In the second position, the ports are fluidly isolated from each other. An external surface of the fluid switch is separated from an internal surface of the chamber by a first micro-gap. Another external surface of the fluid switch is separated from another internal surface of the chamber by a second micro-gap. The first micro-gap and the second micro-gap are fluidly coupled to the chamber, and each have a respective size of less than about five micrometers.
