摘要 |
<p>A valve for controlling the flow and pressure of fluid in a fluid operated system in which a hollow, ported control valve spool is movable in response to selective operation of a manually actuated actuator valve spool to effect modulation of a first fluid flow through the valve. One end of the hollow, ported control valve spool engages a plug portion of a freely floating piston movable in response to fluid pressure from a second fluid source to close a normally open port in the hollow control valve spool.</p> |
