摘要： A plurality of aspirating ejector nozzles are fed with primary fluid which is admitted successively past a modulating valve and throttling orifice to the inlet ports of the nozzles with a portion of the primary fluid being arranged for bypassing the nozzle past a bypass valve controlled by pressure responsive means subject to the pressure of the primary fluid upstream of the throttling orifice.

摘要： A fluid flow control system having a control valve which maintains a constant output flow rate regardless of input flow pressure variations. Three such constant flow valves are disposed in parallel to common inlet and exhaust headers, and hydraulically detented pilot control valves are selectively actuated to vary exhaust flow from the system in discrete steps. A web arrangement in the exhaust header prevents interaction of velocity heads between the flows coming from the three constant flow valves.
摘要翻译：一种具有控制阀的流体流量控制系统，其与输入流量压力变化无关地保持恒定的输出流量。三个这样的恒流阀与共同的入口和排气集管平行设置，并且选择性地启动液压定位的先导控制阀以在离散的步骤中改变来自系统的排气流。排气歧管中的腹板布置防止来自三个恒定流量的流动之间的速度头的相互作用。
