    • A hydraulic system for accommodating fluid pressure variations is provided. The system includes a housing for an actuating piston with the housing having a first end with a hydraulic fluid port and a second end. The actuating piston includes a body portion, having a face, and a rod portion. A first resilient member is confined between the actuating piston and the second end of the housing. A second resilient member is confined between the body portion and the face of the actuating piston. The face of the actuating piston is preferably a pressure accommodating piston which moves relative to the body portion of the actuating piston. Preferably, the second resilient member has a tension force greater than the tension force of the first resilient member. As the actuating piston moves against the bias of the first resilient member toward the second end of the housing in response to hydraulic fluid entering the housing through the fluid port, the movement of the actuating piston is limited by a stop. If there is an increase in hydraulic fluid pressure with the actuating piston in the stopped position, the additional pressure is accommodated by compression of the second resilient member.
    • 提供一种用于容纳流体压力变化的液压系统。 该系统包括用于致动活塞的壳体,壳体具有带液压流体端口的第一端和第二端。 致动活塞包括具有面部的主体部分和杆部分。 第一弹性构件被限制在致动活塞和壳体的第二端之间。 第二弹性构件被限制在主体部分和致动活塞的表面之间。 致动活塞的表面优选地是相对于致动活塞的主体部分移动的压力容纳活塞。 优选地,第二弹性构件具有大于第一弹性构件的张力的张力。 当致动活塞响应于通过流体端口进入壳体的液压流体而抵抗第一弹性构件的偏压朝向壳体的第二端移动时,致动活塞的运动受到停止的限制。 如果在致动活塞处于停止位置时液压流体压力增加,则通过第二弹性构件的压缩来容纳附加压力。

    • A system for electrically detecting different positions of a movable piston within a piston housing of a hydraulic system is provided. The system includes at least two electrically conductive pads mounted on the piston housing at different locations along the path of movement of the piston, an electrically conductive segment mounted on the piston housing along the path of movement of the piston adjacent the conductive pads, and an electrical coupler, such as a spring-loaded conductor, attached for movement with the piston to provide an electrical connection between each conductive pad and the conductive segment as the piston moves along within the piston housing. The system also includes an electronic control unit, which may be a microprocessor, coupled to each conductive pad and the conductive segment to detect electrical connection between each conductive pad and the conductive segment. Each electrical connection corresponds to a specific position of the piston.
    • 提供一种用于电动检测液压系统的活塞壳体内的可移动活塞的不同位置的系统。 该系统包括沿着活塞运动路径的不同位置安装在活塞壳体上的至少两个导电垫片,沿邻近导电垫片的活塞运动路径安装在活塞壳体上的导电段,以及 电耦合器,例如弹簧加载的导体,其被附接用于随活塞一起移动,以在活塞在活塞壳体内移动时在每个导电垫和导电段之间提供电连接。 该系统还包括电子控制单元,其可以是微处理器,耦合到每个导电焊盘和导电段以检测每个导电焊盘和导电段之间的电连接。 每个电气连接对应于活塞的特定位置。

    • An internal combustion engine includes a block defining a plurality of combustion cylinders, an intake manifold fluidly coupled with at least one combustion cylinder, and an exhaust manifold fluidly coupled with at least one combustion cylinder. An EGR valve may be fluidly coupled between the exhaust manifold and the intake manifold. A turbocharger includes a turbine fluidly coupled with the exhaust manifold, and a compressor fluidly coupled with the intake manifold. A microphone is positioned at the compressor inlet or the compressor outlet provides an output signal. An ECU is coupled with the microphone, and controls operation of an actuatable element of a VGT, an EGR valve, and/or an injected fuel quantity, to prevent surge of the compressor, dependent upon the output signal from the microphone.
