<p>An undersea hydraulic coupling has a bleed port for seawater external to the coupling to enter the bore of the female coupling member when the male member is partially withdrawn from the female member. A ring-shaped radial seal positioned between the coupling members allows fluid to enter through the bleed port and flow into the bore, while sealing against the flow of hydraulic fluid out of the coupling. The bleed port and ring-shaped radial seal provide for seawater to fill the vacuum between the coupling members when they are separated, thereby decreasing the separation force required.</p> |
