摘要： A valve assembly selectively varies the timing of the valves in an internal combustion engine cycle by way of a first and second camshaft. Each valve has a shuttle portion and a valve portion. Upper and lower cam followers on the shuttle portion engage with first and second cams on each of the first and second camshafts to move the valve between an open and closed position with reference to a valve seat on an engine block.

摘要： Embodiments relate generally to energy storage systems, and in particular to energy storage systems using compressed gas as an energy storage medium. In various embodiments, a compressed gas storage system may include a plurality of stages to convert energy into compressed gas for storage, and then to recover that stored energy by gas expansion. In certain embodiments, a stage may comprise a reversible compressor/expander having a reciprocating piston. Pump designs for introducing liquid for heat exchange with the gas, are described. Gas flow valves featuring shroud and/or curtain portions, are also described.

摘要： A kinetically unyielding, statically compliant (KUSC) positive return valve action. In one embodiment, a guide is pivotally mounted and rotationally abuts a limiting bench. A pin mounted slidably on the guide is linked to a poppet valve, a driver positioning the pin along the guide. With the valve seated and the driver overtraveled a deflection opens up between the guide and the limiting bench that resolves the overtravel, which deflection is opposed by a forcing spring. As the valve is initially lifted, valve-lift kinetic force is buttressed against the guide mount and the limiting bench, neither of which yields. With increasing lift the pin position passes the guide mount axis to be cantilevered on the guide at maximal valve lift against valve-return kinetic force: this also is unyieldingly buttressed. The action is adjusted by positioning the limiting bench either manually or by hydraulic lash adjuster.
摘要翻译：动力不稳定，静态（KUSC）正回流阀动作。在一个实施例中，引导件枢转地安装并旋转地邻接限制工作台。可滑动地安装在引导件上的销连接到提升阀，驱动器沿着引导器定位销。当阀门就位并且驾驶员越过行程时，偏转在导向器和限位台之间打开，该偏转台解决了超行程，该偏转被强制弹簧相对。当阀门最初抬起时，气门升降动力被抵抗导向架和限位板，两者都不会产生。随着升程的增加，销位置通过引导安装轴线，以在最大阀提升时悬挂在引导件上，以抵抗阀返回动力：这也是不屈服的。通过手动或通过液压间隙调节器定位限位台来调节动作。

摘要： The mass production of the MultiAir/UniAir of Fiat/INA proves that the hydraulic control can reliably actuate the valves of the modern internal combustion engines, making them greener. Removing the valve springs from the valves and controlling by the cam not only the valve opening but also the valve restoring, the hydraulic system has easier work to do, the rev limit increases, the height and the cost of the engine decrease and the engine can operate according all the MultiAir strategies.Optionally, the control by high speed solenoid valves can be replaced by easier and cheaper control wherein the rotation of the oil piston is what varies the valve lift and the valve duration. If necessary, slow, cheap, low power servomotors can micro-align the angular displacement of different oil pistons to balance the load between the cylinders.
摘要翻译：菲亚特/ INA的MultiAir / UniAir的批量生产证明了液压控制可以可靠地启动现代内燃机的阀门，使其更加环保。从阀门拆下阀门弹簧，控制不仅阀门开启而且阀门还原，液压系统更容易做工作，转速限制增加，发动机高度和成本下降，发动机可以根据所有MultiAir策略进行操作。可选地，可以通过更容易和更便宜的控制来代替高速电磁阀的控制，其中油活塞的旋转是什么改变阀提升和阀持续时间。如果需要，慢速，便宜的低功率伺服电机可以微调不同油活塞的角位移以平衡气缸之间的负载。
