    • A valve actuation system is described containing a collapsible pushrod device for use in a reciprocating piston machine cylinder such as an engine. The collapsible pushrod device replaces a conventional pushrod. The system can include a driver base, plunger, and a deactivation pin assembly. In normal operation, the pins lock the driver base and plunger together thereby providing regular valve motion. Under selected conditions, the pin assembly controller unlocks the driver base from the plunger. Valve lift is reduced or eliminated. When eliminated, the cylinder is deactivated. The system can vary the effective compression ratio between higher for cold starting and other selected operating conditions and lower for warmed-up running, as well as trap additional exhaust residuals to assist starting and light load. This is especially useful for Diesel engines. Various means may be used to unlock the pins including oil pressure, bi-metal spring temperature, or electromagnetic activation.
    • 描述了一种阀致动系统,其包含用于诸如发动机的往复活塞机筒中的可折叠推杆装置。 可折叠推杆装置取代了常规推杆。 该系统可以包括驱动器基座,柱塞和停用销组件。 在正常操作中,销将驱动器底座和柱塞锁定在一起,从而提供规则的阀门运动。 在选定的条件下,销组件控制器从柱塞上解锁驱动器底座。 气门升程减少或消除。 取消时,汽缸停用。 该系统可以改变冷起动和其他选择的操作条件下的有效压缩比,并且对于预热运行而言可以改变较低的有效压缩比,以及捕获附加的废气残余物以辅助起动和轻负载。 这对柴油发动机特别有用。 可以使用各种装置来解锁销,包括油压,双金属弹簧温度或电磁激活。

    • A damper is shown for damping the movements of a valve spring in an engine. The valve spring can be housed within the damper or the damper may be located inside of the valve spring. The damper is made from a suitable polymer and has one or more slots located radially to a central axis and one or more rings or bands. The slots can be parallel to the central axis or cut at an angle or curve in the wall of the damper. The rings or bands are located on the outer surface of the damper where the valve spring is located within the damper. The purpose of the slots cut into the polymer damper is to enable the polymer to deflect and conform to the shape of the spring under a radial force provided by a separate circular spring element such as a band, ring, garter spring and others. The rings or bands are located on the inner surface of the damper where the valve spring surrounds the damper. The cross section, number and location of the slots, rings or bands can be adjusted depending on the particular application of the damper and the amount of damping that is desired for the particular application.

    • A valve control device and related method of valve control which enhances performance characteristics of an internal combustion engine that utilizes push rods and extends the useful life of the valve control device is provided. The valve control device includes a valve engagement assembly (70) which, in response to movement of the camshaft (60) associated with the engine, interacts with a first valve closure mechanism (68) associated with the valve such that the valve is efficiently opened and closed. The valve engagement assembly includes a rocker arm (72), which is pivotally connected to the engine and associated with a push rod (74) which is reciprocable in response to movement of the camshaft. Further, a second valve closure mechanism (71) is associated with the push rod for actuating downward movement of the push rod in cooperation, and substantially in unison, with the first valve closure mechanism which is engageable with the rocker arm. Each valve closure mechanism can be a compression spring of predetermined stiffness or elasticity and relative strength. The push rod can be connected to the rocker arm through a ball and socket joint that allows the push rod to rotate and spin during the upward and downward movement of the push rod.
