    Abstract: A valve unit or rectilinear positioning device having a plurality of operating positions and arranged such as to hold the operating position last encountered upon inactivation of the valve or positioning device moving and control means comprising a body including a bore, a slide positioner or slide valve reciprocable in the bore between the two operating positions, at least two elastic ring seals spaced along the bore, and partially recessed into the periphery thereof, said seals having an unexpanded ring diameter substantially equal to or slightly less than the ring diameter of complemental detents or recesses on the slide positioner into which the seals are selectively seated, means for applying fluid pressure to the ring seals and to the ends of the slide positioner or slide valve, and means for locking and unlocking the elastic ring seals to the slide positioner simultaneously with moving it to the next operating position and holding it in that position upon inactivation of the moving means.

    Abstract translation: 一种阀单元或直线定位装置，其具有多个操作位置并且布置成保持最终在阀或定位装置失活时遇到的操作位置移动和控制装置，该装置包括主体，该主体包括孔，滑动定位器或可往复运动的滑阀 在两个操作位置之间的孔中，沿着孔间隔开的并且部分地凹入其周边的至少两个弹性环密封件，所述密封件具有基本上等于或略小于互补棘爪或凹槽的环直径的未膨胀环直径 在所述滑动定位器中，所述密封件被选择性地放置在所述滑动定位器中，用于向所述环形密封件和所述滑动定位器或滑阀的端部施加流体压力的装置，以及用于将所述弹性环密封件锁定并解锁到所述滑动定位器的装置， 它到下一个操作位置，并在mov的停用时将其保持在该位置 意味着。
