摘要： A rack and pinion gear train actuator for a pintle valve. A motor shaft has a pinion gear that engages a large reduction gear having an integral hub gear. The hub gear is a planet gear for a ring gear segment that pivots on a shaft and includes a pinion gear segment that engages a linear rack. The rack is attached to a valve pintle shaft, causing the valve to be opened and closed in response to rotation of the motor shaft. The pintle shaft, return spring, rack, and gears are all assemblable by slip fit. The actuator has a high actuation force, a fast response time, and compact design by virtue of a rack and internal gearing. The stroke of the rack may be changed for use with pintle valves having differing strokes by varying the angle through which the motor operates.

摘要： A dual-poppet valve comprising a valve body having spaced-apart coaxial valve seats and being arranged such that first and second poppets both open into the primary chamber. A first pintle shaft engages the first poppet, and a second pintle shaft engages the second poppet. A motorized actuator having a gear transmission includes a pinion gear. The pintle shafts include opposing gear racks, and the pinion gear engages both racks. Thus, rotation of the pinion gear in a first direction causes both poppets to be lifted from their seats simultaneously, in opposite directions; and counter-rotation engages each poppet with its respective seat. In closing, one poppet engages its seat slightly before the other poppet engages the other seat. The first pintle slides through the first poppet until the second poppet is fully seated by the actuator. The force of the spring fully engages the first poppet with the first seat.
摘要翻译：一种双提升阀，包括具有间隔开的同轴阀座的阀体，并且布置成使得第一和第二弹簧都打开进入主室。第一枢转轴接合第一提升阀，第二枢轴接合第二提升阀。具有齿轮传动装置的电动执行器包括小齿轮。枢轴包括相对的齿条，小齿轮啮合两个齿条。因此，小齿轮在第一方向上的旋转使得两个弹簧都能沿相反的方向同时从其座上升起; 并且反向旋转使每个提升阀与其相应的座椅接合。最后，一个提升阀略微靠在另一个提升阀接合另一个座位之前。第一枢轴滑过第一提升阀，直到第二提升阀被执行器完全固定。弹簧的力完全与第一座椅接合。
