摘要： A conduit arrangement for heavy duty purposes in which a conduit section, such as a length of flexible hose, may be subjected in use to high stresses from pressures attaining several hundred atmospheres, wherein the arrangement provides protection against ruptures and significant leaks and comprises stop valve means at the inlet end of the conduit section, pressure drop type flow sensing means (e.g. an orifice plate or venturi restriction) at the outlet of said section, and pressure comparator means for comparing the pressure drop over the flow sensing means with that over the stop valve means and operative to effect a rapid closing operation of the stop valve means if the ratio of said pressure drops deviates by a certain amount from a predetermined value.

摘要： In a hydrostatic bearing there is provided in known manner pairs of balancing pockets between the coacting bearing surfaces. To counteract the bearing load the pockets of each pair is fed with pressure fluid through a new combined throttle valve which not only distributes the flow of pressure fluid but also its throttling or constricting effect between the pockets of the pair. The valve contains a freely movable roller element cooperating with two pairs of diametrically opposed ports in the valve housing, the ports of one pair individually communicating with each its pocket of the pair of pockets, the ports of the second pair communicating with a pressure source or pump and a low pressure outlet or sump, respectively.
