Abstract:
An undersea hydraulic coupling member comprising:(a) a body section and a probe section, a longitudinal bore extending through both sections, the probe section having a outer surface with a stepped outer diameter and a leading face, the leading face having an aperture therein;(b) a poppet valve in the longitudinal bore in the body section for controlling flow of hydraulic fluid through the bore, the poppet valve slideable between an open position and a closed position, the poppet valve being biased to the closed position;(c) at least one fluid passage in the probe section having a first end in the bore and a second end through the cylindrical outer surface of the probe section, the fluid passage sloping down from the first end to the second end when the body is positioned with the leading face of the probe section facing up; and(d) a valve actuator in the longitudinal bore in the probe section, the value actuator attached to the poppet valve and extending longitudinally through the aperture in the leading face of the bore, the actuator being moveable upon application of longitudinal force thereto to urge the poppet valve to the open position for flow of hydraulic fluid through the fluid passage and the bore.
