Abstract

See full text

A valve includes a valve body including a main passage defining a first volume and a second volume. The valve also includes a valve spool moveable relative to the valve body. The valve spool includes a central vent passage capable of fluid communication with each of the first volume and the second volume. Air flows between the first volume and the second volume through the central vent passage as the valve spool moves relative to the valve body and as the valve changes between an actuated position and a non-actuated position.
