Abstract
Abstract A hydraulic device suitable for installation in a vessel wall and having a positively opening and closing valve, respectively, upon the insertion and withdrawal, selectively, of another functional member. Such a member may be a magnetic debris collector, an electric chip detector, a fluid-sampling element, a thermosensitive probe, a drain attachment and any related accessory, selectively. The practice of this hydraulic device precludes the draining of the fluid and reduces the fluid spillage to a minimum when the accessory members are negotiated.
