摘要： A fluid flow control valve comprises a housing defining a fluid flow passage extending longitudinally therethrough, the housing having opposite ends each defining an opening for flow into and out of the fluid flow passage, and an orifice and diaphragm disposed in the housing. The orifice has a seat at one end thereof facing the diaphragm. The diaphragm has one end face that opposes the seat of the orifice, the seat being configured such that one or more flow control passages are defined between the seat and the one end face of the diaphragm through which the fluid flows. The seat is contoured to include at least two different shapes of channels each promoting localized bending of the diaphragm at a different pressure differential, thereby permitting an expansion of the working pressure range to very low pressure differentials. The localized bending of the diaphragm can be modeled as a simple supported beam bending, which is well understood and readily predicted, thus making the prediction of the diaphragm movement more accurate than prediction of complex diaphragm deflections that occur in many prior flow control valves. Accordingly, the accuracy of the flow control valve can be improved over that of prior valves having complex diaphragm deflection modes.
摘要翻译：流体流量控制阀包括限定纵向延伸穿过其中的流体流动通道的壳体，所述壳体具有相对的端部，每个端部限定用于流入和流出流体流动通道的开口，以及设置在壳体中的孔口和隔膜。孔口在其一端面向隔膜的座椅。隔膜具有与孔口的座部相对的一个端面，座椅构造成使得一个或多个流动控制通道限定在阀座与流体流过的隔膜的一个端面之间。座椅的轮廓是包括至少两个不同形状的通道，每个通道促进隔膜在不同压差下的局部弯曲，从而允许工作压力范围扩展到非常低的压力差。隔膜的局部弯曲可以被建模为简单的支撑梁弯曲，这是很好的理解和容易预测的，因此使得隔膜运动的预测比在许多现有流量控制阀中发生的复杂隔膜偏转的预测更准确。因此，与具有复杂的膜片偏转模式的现有阀相比，可以提高流量控制阀的精度。

摘要： The present invention is directed to a zero crack-pressure, high-flow valve assembly especially suited for use with blood salvage or recovery systems. The valve assembly cooperates with a valve seat defining an opening for selectively providing fluid communication between two adjacent chambers based on a pressure differential between the chambers. The valve assembly includes a disk coupled to a concentric ring support by a plurality of flexible or elastic arms, thereby permitting the disk to move relative to the ring support in a direction that is generally perpendicular to the plane of the ring support and the disk. The connecting arms also define fluid flow passages between the disk and ring support. The valve assembly is mounted so that the disk is normally spaced-apart from the valve seat, allowing fluid to flow between the two chambers. By increasing the relative pressure of the downstream chamber, the disk closes against the valve seat, blocking the opening.

摘要： The present invention relates to an excess flow valve system having a sliding poppet within a chamber with an orifice at one end, wherein the closing flow rate settings can be adjusted. Precise adjustments can be made externally by turning a threaded member extending through the valve, which causes a retainer, threadably located on the member, to move laterally within the chamber. This movement causes an angled surface on the retainer to engage and slide in relation to a similarly angled surface on the poppet. As the poppet is urged toward the retainer by a coiled spring, the poppet is moved longitudinally within the chamber, either toward or away from the orifice. Turning the threaded member enables the maximum travel distance of the poppet, and therefore, the threshold flow rate of the valve, to be precisely set. Additional means for broadening the range of settings, without replacing the spring or changing the orifice size, can also be provided, such as spacers to change the spring tension and multiple phase settings on the valve housing.
摘要翻译：本发明涉及一种在具有在一端具有孔口的腔室内具有滑动提升阀的过流阀系统，其中可以调节闭合流量设定值。通过转动延伸穿过阀的螺纹构件，可以在外部进行精确的调节，这使得螺纹地位于构件上的保持器在腔室内横向移动。该运动导致保持器上的倾斜表面相对于提动阀上的类似倾斜的表面接合和滑动。当提升阀被螺旋弹簧推向保持器时，提升阀在腔室内纵向移动或朝向或远离孔口移动。旋转螺纹构件能够精确地设定提升阀的最大行程距离，因此阀的阈值流量。还可以提供用于扩大设定范围的附加装置，而不需要更换弹簧或改变孔口尺寸，例如间隔件，以改变阀壳体上的弹簧张力和多相设置。

摘要： A flow sensor device includes a main passage having a normally open shut off valve therein which is configured to shut off at a predetermined rate of air flow therethrough. The shut off valve includes a seating structure and a centering structure positioned within the main passage, a sealing member being positioned between the seating structure and centering structure. The sealing member is biased toward the centering structure by a resilient member. Air flow through the main passage exerts a force on the sealing member which pushes the sealing member toward the seating structure. When the force caused by the air flow exceeds the opposing force of the resilient member, the sealing member contacts the seating structure in a sealing relationship such that air flow through the main passage is substantially eliminated. The flow sensor device may also include a controllable release valve and/or a controllable reset valve, enabling control of the shut off valve of the main passage. Further, an air pulse distribution device is also provided for controlling the reset valves and/or release valves of a plurality of flow sensor devices.

摘要： An improved valve assembly for automatically priming a hydraulic pump during a suction-fed application wherein the pump must draw fluid from within a holding tank for subsequent pressurization and transmission by the pump. The valve assembly of the present invention is provided in fluid communication with the outlet line of the pump and is capable of sensing the difference between fluid and air such that the air disposed within the pump at start-up may be quickly and efficiently bled from the system before the valve automatically closes once the fluid has been drawn into the pump in an amount sufficient to bring the pump into a fully primed condition. The valve assembly includes a housing member, a poppet member, a biasing means, and sealing means. The housing member includes a bore extending between an inlet aperture and an outlet aperture, and a slotted shoulder member extending radially inward from the inlet aperture. The biasing means biases the poppet member between a priming mode, wherein the poppet member is disposed in contact with the shoulder member such that a path of fluid communication extends from the slots of the shoulder member to the outlet aperture, and a closed mode, wherein the poppet member is disposed in contact with the sealing means such that the aforementioned path of fluid communication is closed.

摘要： A rapid acting flow limiting valve is provided for an autoclave processing system. In this environment, each of a plurality of parts is placed in immediate proximity with a tool, then impressed into congruent engagement with the tool by an overlying vacuum bag, the interior of the vacuum bag being subjected to a vacuum via a vacuum manifold connecting all of the parts to a source of the vacuum, the interior of the vacuum bag being subjected to pressure. A first conduit leads from the chamber of the valve housing to the interior of the vacuum bag for its associated part, and a second conduit leads from the chamber to the vacuum manifold. An annular seal is positioned concentrically with an opening from the chamber into the first conduit. A flexible disk-shaped floating piston diaphragm assembly is peripherally fixed to the housing and is movable between an open position distant from the seal and a closed position engaged with the seal to thereby block flow through the first conduit. An annular spring concentric with the annular seal biases the floating piston diaphragm assembly toward the open position. Should the vacuum bag for a second part rupture, which would cause pressurized fluid flow to be introduced into the vacuum manifold toward the valve associated with the first part, the diaphragm assembly for that valve is moved to the closed position preventing pressurized fluid flow into the vacuum bag for the first part.

摘要： A discharge valve assembly for use in a fluid displacement apparatus has a suction chamber and a discharge chamber on one side of a valve plate, a compression chamber on the other side of the valve plate and a passage formed in the valve plate extending between the compression chamber and the discharge chamber. The discharge valve assembly comprises a valve limiting device secured to the valve plate for limiting the bending movement of a valve member. The valve member is bent away from the valve plate when all external pressure influences are removed. Noise and vibration caused by the striking of the valve member against the valve seat and the retainer member are thereby decreased.

摘要： A method and apparatus is described for limiting transient motions between an aircraft power member and aircraft structure. The apparatus incorporates a coupler (20) for use with inertial-type mounts and includes a body portion (21) having a coupler piston (32) telescopically received therein. Upon exceeding a transient relative motion which causes a fluid flow velocity to be exceeded, seat (38) formed on coupler piston (32) interacts with lip (39) on body portion (21) to cause a fluid flow restriction. This method and apparatus restricts and limits transient motions, i.e., acts as a snuffer, to limit further relative motion between an aircraft power member (54) and an aircraft structural member (52). The coupler piston (32) preferably includes a flexible seal (38) formed thereon and orifice (40) therethrough for providing additional throttle-type damping upon snubbing. This method and apparatus is particularly useful in inertial-type fluid mounts for mounting aircraft engines, fluid pylon isolators for helicopter pylon isolation, and Fluid Torque Restraint (FTR) systems for aircraft for limiting transient motions under certain conditions, such as during takeoff, landing, and maneuvers, yet providing isolation under normal operating conditions.
