摘要： A variable valve actuation system to actuate and control the seating velocity of an internal combustion engine valve is disclosed. The system may comprise a rocker arm that includes first, second and third contact surfaces. The first contact surface may contact the engine valve. A hydraulic lost motion system may contact the rocker arm at the second contact surface, and a mechanical valve train element may contact the rocker arm at the third contact surface. The lost motion system may include a slave piston with a valve seating device incorporated therein. The lost motion system and the mechanical valve train element may be provided side by side at the end of the rocker arm opposite that of the engine valve.

摘要： A valve bridge system comprises a valve bridge body configured to extend between at least two engine valves of an internal combustion engine. The valve bridge body comprises a through-bore configured to align with a first engine valve and to receive a bridge pin. A bridge pin boss has the through-bore formed therein, has a longitudinal length and terminates in an upper surface. The longitudinal length is configured such that the upper surface of the bridge pin boss contacts a surface of the auxiliary rocker arm to resist uncontrolled movement of the valve bridge when the valve bridge is in an uncontrolled state relative to the at least two engine valves.

摘要： A system for controlling actuation of an engine valve comprises a pivot and a torsion spring having first and second legs operatively connected to the pivot. A lever arm is adjustably affixed to and extending away from the pivot, and is further rotatable about a pivot axis of the pivot between a retracted position and an extended position and vice versa relative to a motion conveying component. Furthermore, a housing is provided having a pivot bore formed therein with the pivot rotatably disposed in the pivot bore. The housing further comprises a first and second openings intersecting with the pivot bore such that the first and second legs extend out of the first opening and the lever arm extends out of the second opening. When a first force is applied by the motion conveying component to the lever arm, such first force maintains the lever arm in the extended position.

摘要： For controlling motion of a movable part, a device comprises a first chamber and a second chamber in fluid communication with each other via a variable orifice that is responsive to pressure within the first chamber. Movement of the movable part is thereby at least partially controlled by flow of a fluid from the first chamber to the second chamber via the variable orifice. An increase in pressure in the first chamber may cause an increase in orifice area, whereas a decrease in pressure may cause a decrease in the orifice area. Pressure-dependent elements that change geometries and/or the pressure-based opening/closing of one or more bypass channels may be used for this purpose. Where bypass channels are used, a valve may be opened/closed based on an operating parameter of a system in which the movable part is a component. Such a system may comprise an internal combustion engine.
摘要翻译：为了控制可移动部件的运动，装置包括通过响应于第一腔室内的压力的可变孔口彼此流体连通的第一腔室和第二腔室。因此，通过可变孔口将流体从第一腔室流向第二腔室至少部分地控制活动部件的移动。第一腔室中的压力增加可导致孔口面积的增加，而压力的降低可导致孔面积的减小。可以使用改变一个或多个旁路通道的几何形状和/或基于压力的打开/关闭的压力依赖元件用于此目的。在使用旁路通道的情况下，可以基于可移动部件是部件的系统的操作参数来打开/关闭阀。这样的系统可以包括内燃机。

摘要： Devices and related methods are disclosed that generally involve the selective deactivation of one or more engine valves. In one embodiment, a split-cycle internal combustion engine is provided in which a high-speed trigger valve is used to fill and drain a hydraulic tappet that forms part of a lost-motion system of an engine valve. A spool valve can be used to selectively disconnect the tappet from the trigger valve, thereby deactivating the associated engine valve (i.e., preventing the engine valve from opening). The devices and methods disclosed herein also have application in conventional internal combustion engines and can be used with inwardly-opening and/or outwardly-opening valves.
