    • An improved design for pushrod operated internal combustion type engines. This invention eliminates the valve spring altogether. In current engines of this type a cam lobe provides the positive upward force to the system to open an intake or exhaust valve and a valve spring provides the constant force to close the valve. This invention uses two cam lobes, an open cam lobe 22 and a close cam lobe 23; two pushrods, and open pushrod 24 and a close pushrod 25; and two geared rockers, a open geared rocker 26 and a close geared rocker 27. A valve stem box retainer 32 is required to pull the valve into a closed position. Positive upward force from the cam shaft is used to both open and close an intake or exhaust valve. The key is that only one of the cam shaft lobes drives the system at a time. If the close valve cam lobe 21 is providing the upward force to close the valve than the open valve cam lobe 20 is not engaged. Since the open and close rockers are geared and engaged into each other, the lifter/pushrod/rocker combination that is not actively driving the valve is controlled by the one that is.
    • 推进式内燃式发动机的改进设计。 本发明完全消除了阀弹簧。 在这种类型的当前发动机中,凸轮凸角为系统提供正向上的力以打开进气门或排气门,并且阀弹簧提供恒定的力来关闭阀。 本发明使用两个凸轮凸角,一个打开的凸轮凸角22和一个闭合凸轮凸角23; 两个推杆,打开推杆24和一个靠近推杆25; 和两个齿轮摇臂,一个敞开的齿轮摇臂26和一个靠近的齿轮摇臂27.需要一个阀杆箱保持架32来将阀拉到关闭位置。 来自凸轮轴的向上的力被用来打开和关闭进气门或排气门。 关键是一次只有一个凸轮轴叶片驱动系统。 如果关闭阀凸轮凸角21提供关闭阀的向上的力比打开的阀凸轮凸角20未接合。 由于开闭式摇杆相互啮合,因此不主动驱动阀门的升降器/推杆/摇臂组合由此控制。

    • The invention relates to a desmodromic system in which a valve stem is arranged to be acted upon directly, or by way of rockers, by an opening cam and a closing cam rotatable together at constant or varying angular velocity in synchronism with the rotation of the engine crankshaft, and in which a compliance device is incorporated in the transmission train from the cams to the valve stem, the compliance device comprising two cup-shaped members nested together with a limited relative movement between and resiliently urged away from one another, the compliance device operating to provide zero clearance when the valve is open and maximum clearance when closed to accommodate valve recession and thermal expansion.

    • A direct acting cam-valve assembly for an internal combustion engine having an engine block means defining a port includes an internal/external cam fixed to an engine driven camshaft and a direct acting cam follower having one end thereof driven reciprocably by the internal/external cam to push an associated poppet valve from a closed position to an open position and to pull the valve from the open position to the closed position. A conventional hydraulic lash adjuster is operatively positioned in the cam follower whereby one end of the lash adjuster abuts against the free valve stem end of the valve and a spring is operatively positioned in the opposite end of the cam follower and operatively connected to the valve stem end of the valve whereby to, in effect, operatively connect the valve to the cam follower.

    • The valve control system for the continuous adjustment of the control times and strokes of the valves of an internal combustion engine has an eccentric shaft which is common to the intake and exhaust valves and is arranged in the cylinder head and which has for each cylinder a single eccentric for the driving of two connecting rods 4. The two connecting rods 4 form between their longitudinal axes an angle of less than 180.degree. and each of them drives a swing cam 6. For the positive control of the intake and exhaust valves respectively each swing cam is in engagement in both directions of swing in form-locked manner with the fork section of a valve rocker which is pivotally connected to the associated valve. The eccentric shaft is displaceable transversely to its longitudinal axis in a direction such that by a displacement of the eccentric shaft the distances between the eccentric and the axes of the two valve rockers are simultaneously decreased and increased respectively.
