摘要： The disclosed computer-implemented method may include a fluidic device comprising a chamber, an inlet port coupled to the chamber and configured to convey fluid to the chamber, and an outlet port coupled to the chamber and configured to convey the fluid from the chamber. The fluidic device may also have a restricting region that (1) is dimensioned to restrict a flow of the fluid through the outlet port when the pressure in the chamber is below a threshold level and (2) is configured to move in a manner that allows a flow rate of the fluid through the outlet port to increase when pressure in the chamber reaches the threshold level.

摘要： A stepper-motor gas valve control is disclosed that includes a main diaphragm in a chamber that controllably displaces a valve relative to an opening in response to changes in pressure, to adjust fuel flow through the valve. A servo-regulator diaphragm is provided to regulate flow to the main diaphragm, to thereby control the rate of fuel flow. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm, to control fluid flow to the main diaphragm. A controller mounted on the stepper-motor regulated gas valve control receives and converts an input control signal from a heating system to a reference value between 0 and 5 volts, and selects a corresponding motor step value. The control responsively moves the stepper-motor in a step wise manner to displace the servo-regulator diaphragm and thereby regulates the rate of fuel flow through the valve.

摘要： Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.

摘要： A valve assembly for controlling gas delivery from a higher pressure fluid source to a lower pressure processing tool. The valve assembly includes a valve poppet movingly engageable with a valve seating member and a fluid permeable insert positioned between the valve poppet and the valve seating member that is unexposed to flowing fluid when the valve poppet is in a closed position thereby preventing fluid flow through the valve assembly and providing a diffusional path for transfer of all flowing fluid when the valve poppet is in an open position. The permeable insert can be inserted into the sealable and engageable surface of either the valve seat member or the valve poppet.

摘要： A minimal wear valve assembly which includes a fluid reservoir having an inlet port and an outlet port for passage of the fluid therethrough. The reservoir defines a valve seat about and downstream of the outlet port. The assembly includes a valve having a first substantially non-deformable valve surface. The valve is movable with respect to the valve seat from an open condition which permits flow of the fluid through the outlet port to a closed condition which prevents flow of the fluid through the outlet port. The valve supports a sealing member for movement with the valve. The sealing member has greater compressibility than the first valve surface and provides a seal between the first valve surface and the valve seat upon movement of the valve to the closed condition.

摘要： In an automotive engine exhaust pipe having a main flow passage and a bypass flow passage, the exhaust gas flows through the bypass flow passage having an heater-provided catalyst when an engine starts. After a main catalyst reaches a catalytic activation temperature, a switching valve switches the exhaust gas to flow through the main flow passage. The main shaft is divided into a driven shaft inserted into a bearing hole and a driving shaft inserted into another bearing hole, and therefore, a total length thereof in an axial direction is shorter than a length of the main shaft without having segments. Therefore, even though the driven shaft and the driving shaft are deformed into the arch shape, a deformation amount thereof is reduced so that inner peripheries of the bearing holes are not rubbed against the shafts. Since the driving shaft is smaller in diameter than the driven shaft, even though a cross section of the driving shaft is elliptically strained, the inner periphery of the bearing hole is not rubbed against the driving shaft. As a result, since a clearance between the driving shaft and the bearing hole can be narrowed, the exhaust gas from the clearance can be prevented from leaking.
摘要翻译：在具有主流路和旁通流路的汽车发动机排气管中，当发动机起动时，排气通过具有加热器的催化剂的旁通流路流动。在主催化剂达到催化活化温度之后，切换阀切换排气流过主流道。主轴分为插入轴承孔的从动轴和插入另一个轴承孔的驱动轴，因此其轴向的总长度短于不具有段的主轴的长度。因此，即使从动轴和驱动轴变形为拱形，其变形量也减小，使得轴承孔的内周不会摩擦轴。由于驱动轴的直径小于从动轴的直径，即使驱动轴的横截面是椭圆形的，轴承孔的内周也不会摩擦驱动轴。结果，由于驱动轴和轴承孔之间的间隙可以变窄，所以能够防止来自间隙的废气泄漏。
