Abstract:
An undersea hydraulic coupling member comprising:(a) a body section attached to a probe section, the probe section having a smaller diameter than the body section, and having a stepped cylindrical bore having a first section in the body section and a second section in the probe section, a valve seat between the first section and second section in the bore, and a poppet valve in the first section of the bore slideable between a closed position against the valve seat and an open position spaced from the valve seat; and; (b) a valve actuator extending longitudinally from the poppet valve through the second section of the bore, the valve actuator having an outer diameter greater than one half of the internal diameter of the second section of the bore; and (c) a guide slideable in the second section of the bore having an outer diameter greater than the valve actuator, the guide having a central bore through which the valve actuator extends the guide having a generally cylindrical shape with a plurality of apertures therein sufficient for hydraulic fluid to pass longitudinally therethrough.
