A lubrication conduit communicates with the trunnion bore to supply a lubricant to the trunnion bore.  A retention valve is positioned within the lubrication conduit for preventing drainback of the lubricant within the lubrication conduit. The retention valve includes a valve body extending along a portion of the length of the conduit, with the valve body having an outer surface approximately the same size as the inner surface of the lubrication conduit. The retention valve also includes a plurality of grooves in the surface of the valve body, with the grooves extending generally in the direction of the length of the conduit, and the grooves being large enough to enable the passage of the lubricant under pressure past the retention valve, but small enough to prevent drainback of lubricant within the lubrication conduit.

Abstract: The invention provides a variable shape device, with or without a base, for presenting all types of bouquets individually, vertically and without water. The device (1) is made of water- and deformation-resistant materials, with an adjustable attachment means having a male (3) and a female portion (4). The assembled device has a tapered portion (5) with tabs (11), which adapts to every type of bouquet, and a stable base (2). The openings (6) enable the bouquet to be initially retained in the device, for individual presentation, by any fastening means inserted in the openings. A  water-tight decorated sheet (8), extending towards the top (5) of the outer walls (1) and adhering to members (7), is retained by a ribbon (21) on blade members which holds together the sheet, the device and the bouquet, the sheet providing water-tightness to the device (8). Water (10) introduced into the device collects at its base (2), thus providing stability to the bouquet and converting the device into a disposable flower-pot. In the same way, a cylindrical sleeve (20) provides for the transport, by air or by road, with very little water, of a bunch of 40 flowers from the producing country to a buyer country.
