Abstract: A valve control system may include an adjustable camshaft that includes an outer shaft and an inner shaft that extends through the outer shaft. The valve control system may further include a phase shifter that comprises a first control element and a second control element that can be rotated relative to the first control element. The outer shaft and the inner shaft may each be connected with a control element. The valve control system may also include a stop coupled with the outer shaft in a torque-proof manner, as well as a counter-stop coupled with the inner shaft in a torque-proof manner. A maximal angle of rotation of the inner shaft in the outer shaft may be determined by the stop bordering on the counter-stop.

Abstract: A desmodromic valve system which provides direct bidirectional displacement of a valve stem of an internal combustion engine without the aid of a rocker arm, utilizing a semirigid basket operating in conjunction with a plurality of cams for each valve. The basket is disposed about the camshaft of the engine and secured to the valve stem by an integral retainer on a bottom portion of the basket, and is constrained to motion along the valve stem axis. The basket has a pair of downwardly oriented cam followers in the upper portion thereof, spaced apart from the valve stem axis. A central cam and a parallel pair of side cams are fixedly mounted on the camshaft so as to rotate therewith, the cams substantially surrounded by the basket and cooperating therewith to provide reciprocating valve action with positive bidirectional drive. The central cam is aligned with the valve stem axis, and the side cams are spaced apart from the valve stem axis, parallel to the central cam and respectively aligned with the cam followers. During a first part of a valve cycle, the central cam pushes the valve stem down so as to positively open the associated valve, and the valve stem pulls said basket down with it via the retainer. During a second part of the valve cycle, the side cams push the basket up via their respective cam followers and thereby cause the basket to pull the valve stem so as to positively close the valve.

Abstract: A rocker arm has a first roller for engaging a first rotatable cam surface, whereby at least part of the rocker arm can be pivoted by at least the first rotatable cam surface to move a valve to cause a first valve event, and a further roller for engaging a further rotatable cam surface, whereby at least part of the rocker arm can be pivoted by the further rotatable cam surface to move the valve to cause a second valve event which is different from the first valve event. The rocker arm is configurable in a first mode of operation in which one of the first and second valve events occur and a second mode of operation in which both the first and second valve events occur or the other of the first and second valve events occur.

Abstract: 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. The telescoping motion which limits the motion of the valve may occur in one or more steps.

Abstract: An electromagnetic valve apparatus with nonlinear springs for variable valve timing in an internal combustion engine. The apparatus includes a valve, floating spring assembly, translational cam, and motor. The cam and spring serve to minimize lash and valve stem bending forces. During opening and closing of the valve, spring potential energy is converted into valve kinetic energy and then back into potential energy at the end of the motion. The potential energy is then available for the next opening/closing event. The motor initiates motion, replaces friction and vibration losses, and terminates motion. However, the motor supplies minimal energy as the valve opens and closes, and vice-versa, naturally due to combined effects of system inertia and the nonlinear spring. In addition to valve control, the apparatus may be applied to fuel injectors, or any reciprocating linear or rotary mechanism where electronic control is used.

Abstract translation: 一种用于内燃机可变气门正时的非线性弹簧的电磁阀装置。 该装置包括阀，浮动弹簧组件，平移凸轮和马达。 凸轮和弹簧用于最大限度地减少间隙和阀杆弯曲力。 在阀的打开和关闭期间，弹簧势能被转换成阀动能，然后在运动结束时回到势能。 潜在的能量随后可用于下一个开/关事件。 电机启动运动，代替摩擦和振动损失，并终止运动。 然而，当阀门打开和关闭时，电机提供最小的能量，反之亦然，这是由于系统惯性和非线性弹簧的组合效应。 除了阀控制之外，该装置可以应用于燃料喷射器，或者使用电子控制的任何往复式线性或旋转机构。
