摘要： A surgical system having a cassette with an aspirant collection chamber and an aspiration exhaust line that drains into the aspirant collection chamber. A fluid line containing a valve allowing fluid from the irrigation fluid container to be vented into the aspirant collection chamber. A source of pressurized air is connected to the irrigation fluid container and is used to pressurize the fluid container. When the pressure within the fluid container needs to be increased, pressurized air from the pressurized air source is allowed to enter the fluid container. When the pressure within the fluid container needs to be decreased, irrigation fluid is allowed to be bled out of the fluid container and inter the collection chamber. In this manner, a direct fluidic connection with the gas contained within the fluid container does not need to be maintained.

摘要： A proportional flow control valve, for controlling fluid flow through a flexible tube, includes first and second jaws on opposing sides of the tube. An actuator drives one of such jaws for adjusting the separation distance therebetween. When the valve is open, the separation distance is small enough to partially deform the tube without significantly restricting fluid flow. When the valve is closed, the separation distance is just small enough to essentially block fluid flow. A control system controls the actuator to determine such separation distance. Such valve can be used within a level control system for controlling the thickness of a work material in a slurry form cast upon a moving belt. A fluid reservoir is disposed above the belt, and the control valve adds slurry to the reservoir. A lens disposed near the moving belt and above the reservoir is coupled by fiber optics to a remote sensor for detecting the height of the slurry. A control circuit responsive to the light sensor regulates the flow rate of the control valve.
摘要翻译：用于控制流过柔性管的流体的比例流量控制阀包括在管的相对侧上的第一和第二钳口。致动器驱动这些夹爪中的一个以调节其间的间隔距离。当阀门打开时，分离距离足够小以使管子部分变形，而不会明显地限制流体流动。当阀门关闭时，分离距离足够小，基本上阻止流体流动。控制系统控制致动器以确定这样的间隔距离。这种阀可以用于液位控制系统中，用于控制铸造在移动带上的浆料形式的工件材料的厚度。流体储存器设置在带上方，并且控制阀将浆料添加到储存器。设置在移动带附近和储存器上方的透镜通过光纤耦合到远程传感器，用于检测浆料的高度。响应于光传感器的控制电路调节控制阀的流量。

摘要： An intercept valve for fluids, comprising a tubular element (2) made of a deformable material, which internally defines a passage provided with an inlet (3) and an outlet (4) for a fluid to be intercepted. The tubular element (2) is housed internally of a second tubular element (5) made of steel and having an inlet (7) through which, on command, a pressurised fluid is introduced which closes the passage by laterally choking the tubular element (2). In an open configuration, a median section of the tubular element (2), which is choked to close the tubular element (2), is slightly pre-choked in a preferred choking direction and is free to expand in a direction which is transversal to the preferred choking direction. The valve guarantees a sealed closure. The valve can be used in particular in a device for filling containers with a liquid product.

摘要： An extractor valve assembly for controlling fluid flow in a fluid flow path. The extractor valve assembly comprises an elastic valve conduit having an outer surface with a pair of grooves. The pair of grooves are formed on opposite sides of the outer surface and intersect a pinch circumference of the elastic valve conduit, and are parallel to a central axis of the elastic valve conduit. When the elastic valve is pinched along the pinch circumference by pinch blades, pinch corners are formed at the pair of grooves, such that the pinching action completely blocks fluid flow. Additionally, first and second pairs of symmetric tabs are formed on the elastic valve on opposite sides of the pinch blades, to reduce stress along the portion of the pinch perimeter which comes in contact with the pinch blades.
