Abstract: A gas flow adjusting device is provided, which includes a tube body, a first horizontal shaft, a second horizontal shaft, two leaf structures, a torsional spring and two linkage assemblies. The first and second horizontal shafts are disposed in an accommodating space of the tube body and spaced apart from each other along an axial direction of the tube body. The leaf structures are pivoted on the first horizontal shaft and have a swinging direction identical to the axial direction. The torsional spring is sleeved around the second horizontal shaft and provides a resilient force along the axial direction. The linkage assemblies are connected to the leaf structures respectively, and each of the linkage assemblies is connected to the second horizontal shaft and the torsional spring. Therefore, when the leaf structures swing to different angles, the twisting amounts of the torsional spring are minimally varied.

Abstract: A bleed air pressure regulation system for an aircraft anti-icing system comprises a first, upstream pressure regulating valve and a second, downstream pressure regulating valve arranged in series in a bleed airflow path. The respective pressure regulating valves each have a regulating pressure chamber in fluid communication with a respective pressure setting valve.

Abstract: A transmission includes a latch valve with latched and de-latched states. In the de-latched state, the latch valve directs a control pressure to a clutch apply circuit. In the latched state, which is entered in response to a control pressure higher than a latch pressure, the latch valve directs a line pressure to the clutch apply circuit. A controller manages the transition from latched to de-latched differently depending upon the transmission input torque and gear state. At high transmission input torque, the controller first reduces the control pressure to rapidly accelerate a spool in the latch valve, and then increases the control pressure to prevent clutch slip. At low torque, the controller reduced the pressure to an intermediate value during the transition and then reduces it again. At moderate torques, the controller reduces the pressure directly to a target pressure in a single step.

Abstract translation: 变速器包括具有闩锁和非锁定状态的闩锁阀。 在解锁状态下，闩锁阀将控制压力引导到离合器施加电路。 在响应于高于闩锁压力的控制压力而进入的闩锁状态下，闩锁阀将线路压力引导到离合器施加电路。 控制器根据变速器输入扭矩和档位状态管理从锁定到非锁定状态的转换。 在高变速箱输入扭矩时，控制器首先降低控制压力，快速加速滑阀中的阀芯，然后提高控制压力，防止离合器打滑。 在低扭矩时，控制器在转换期间将压力降低到中间值，然后再次减小。 在中等转矩下，控制器将压力直接降低到目标压力的一个步骤。

Abstract: Hydraulic bump stops and bi-directional diverter valves may be used to protect hydraulic systems, including, for example in one embodiment, the hydraulic actuators of an active suspension system, from damage due to operation outside the normal operating range of the system. In some embodiments, a hydraulic bump stop may be used to slow down the motion of a piston at the extremes of the compression and/or extension strokes of an actuator. In another embodiment, a diverter valve may be used to protect a hydraulic motor/pump in a hydraulic system from an over-speed condition. When the piston in an active suspension system actuator moves at a speed in excess of a threshold value, one or more diverter valves may be used to divert flow away from the hydraulic motor/pump. In some embodiments, a diverter valve may be a dual or single spool bi-directional diverter valve.
