摘要： Provision of flow control arrangements which can be switched from high flow restriction to low flow restriction or vice versa are desirable. It is known to use switched vortex valves comprising a vortex chamber having a diverter portion which jets a through flow into either radial presentation to an outlet or tangential presentation with differential flow restrictions. Typically deflection is through cross flows presented from control ports as determined by mechanically actuated and controlled valves. Sensors are required to determine pressure differentials in order to actuate these moving part valves. By providing association between the control ports and an outlet path along with appropriate configuration and sizing of the flow regulators switching states can be provided through the cross flows presented via the flow regulators between the high and low through flow restriction. The flow regulators generally comprise orifice restrictors, diffusers/venturi arrangements or vortex throttles.

摘要翻译： 提供可以从高流量限制切换到低流量限制或反之亦然的流量控制装置是理想的。 已知使用包括具有分流器部分的涡流室的开关式涡旋阀，该分流器部分将通过流动的径向呈现射流到具有差异流动限制的出口或切向呈现。 典型的偏转是通过由机械致动和控制的阀确定的从控制端口提供的交叉流。 传感器需要确定压差以便致动这些移动部件阀。 通过提供控制端口和出口路径之间的关联以及流量调节器的适当配置和尺寸调整，可以通过在高流量和低流量限制之间经由流量调节器呈现的交叉流提供开关状态。 流量调节器通常包括节流孔，扩散器/文氏管布置或涡流管。
