Druckausgeglichenes Rohrventil für hydraulische Kupplungen
摘要
<p>An undersea hydraulic coupling having a poppet valve movable between an open and a closed position is disclosed. The poppet valve operates without substantial fluid pressure exerted axially against the face of the poppet valve. When the poppet valve is opened, radial passages are interconnected through an annular cavity between the poppet valve body and the valve bore.</p>
