摘要： An electric valve including, housed within a valve body, a nut having a central shaft; a screw threadingly engaged within the nut and fixed thereto to prevent the nut from turning around the screw; and a seal mounted to the central shaft and configured to move freely with respect to the central shaft, both axially and rotatably there-about. The valve further includes sliding bearings disposed between the nut and the seal and disposed between the nut and a base of the screw; a lip correspondingly disposed with respect to the seal and reversibly engagable therewith. A projection is attached at a periphery of the nut; and a limiter is positioned in an inner side of the valve body, configured so that the projection is abuttable therewith. Due to the slide bearings, neither during opening of the valve or closing of the valve does the seal slide on the lip. (From US10400907 B2)
