摘要： A valve for controlling an emergency brake system on an aircraft. The valve has separate poppets for controlling the flow of fluid from a supply line to the brake cylinders and from the brake cylinders to a tank return line. The poppets act on each other. A dampening orifice restricts fluid flow around one of the poppets thereby limiting the rate at which that poppet opens and closes. An actuator applies an externally generated control force to the poppets to activate and de-active the emergency brake system.

摘要： A method and apparatus are disclosed for generating a second clock signal, having a second effective clock frequency, from a first clock signal, having a first effective clock frequency. Clock pulses of the first clock signal are counted to generate a count value. When the count value reaches a predetermined blanking value, a blanking signal is generated. The blanking signal blanks at least one clock pulse of the first clock signal. The process is repeated multiple times at a predetermined rate corresponding to the predetermined blanking value to generate the second clock signal.

摘要： A flow regulator includes a body with an aperture into which an inlet and an outlet open. A pin has a bore extending therein and communicating with the outlet. A first aperture, a second aperture and a bypass orifice are spaced longitudinally along the pin and extend there through opening into the bore. A valve member is slideably located around the pin and is biased by a spring into a first position along the pin in which the valve member closes the first aperture while opening the second aperture. When a pressure differential between the inlet and outlet exceeds a first level, the valve member moves away from the first position and begins covering the second aperture. Thereafter continuing increase of the pressure differential above a greater second level results in the valve member moving into a second position at which both the first and second apertures are closed. However in the second position, a secondary flow path exists between the inlet and the outlet through the bypass orifice. Further increase of the pressure differential significantly above the second level causes the valve member to move into a pressure relief position in which the first aperture is open while the second aperture remains closed.
摘要翻译：流量调节器包括具有孔的主体，入口和出口打开。销具有在其中延伸并与出口连通的孔。第一孔，第二孔和旁通孔沿着销纵向间隔开并且通过开口延伸到孔中。阀构件可滑动地位于销周围，并且通过弹簧被偏压到沿着销的第一位置，在该第一位置中阀构件关闭第一孔，同时打开第二孔。当入口和出口之间的压力差超过第一水平时，阀构件移动离开第一位置并开始覆盖第二孔。此后，压差的继续增加超过更高的第二水平，导致阀构件移动到第二和第二孔闭合的第二位置。然而，在第二位置，通过旁通孔口在入口和出口之间存在二次流动路径。压力差的进一步增加明显高于第二水平，导致阀构件移动到压力释放位置，其中第一孔开启，而第二孔保持关闭。

摘要： An apparatus includes a reservoir of a pressurized fluid connected to a supply conduit. A fluid powered actuator has a first port and an second port. A volumetric flow regulator has a valve element that controls fluid flow between an inlet chamber which receives fluid from the supply conduit and an outlet chamber connected to the first port of the fluid powered actuator. A sensing orifice is coupled between the inlet chamber and the outlet chamber of the volumetric flow regulator, such that the valve element varies flow of fluid between the inlet chamber and the outlet chamber in response to a pressure differential across the sensing orifice. This apparatus ensures relatively constant velocity operation of the fluid powered actuator under varying load conditions. A damping mechanism is disclosed for slowing the fluid powered actuator as an end of its travel approaches.

摘要： An apparatus controls fluid flow to an actuator. A feedback mechanism responds to a pressure differential that occurs across the actuator by altering the fluid flow. That pressure differential indicates acceleration of the actuator that can occur when the load acting thereon varies. Thus as the actuator accelerates, the apparatus reduces the flow of fluid which counteracts the acceleration and maintains the actuator speed relatively constant. A unique directional control valve incorporates the feedback mechanism that functions regardless of the direction in which the actuator moves.

摘要： A hydraulic valve includes a body with bore, a supply port coupled to a first chamber, and a return port connected to the bore and the control chamber. A brake port enables the wheel brake to be connected to the bore, while a brake actuator passage enables pressurized fluid to be introduced into the bore. An orifice is between the supply passage and a second chamber and a nozzle couples the second chamber to the control chamber. A servo valve has a flapper that controls flow of fluid through the nozzle. A valve spool in the bore has a first position at which the brake actuator passage is coupled to the brake passage, and a second position at which the return passage is coupled to the brake passage. The position of the valve spool is determined by pressures in the first chamber and the second chamber.
