摘要： An improved design for valve operation in internal combustion type engines which incorporate an overhead cam. This invention eliminates the valve spring. In current engines of this type an overhead cam lobe provides the force to the system to open an intake or exhaust valve and a compressed valve spring provides the stored energy to force the valve back closed. This invention uses two cam lobes on an overhead cam 15, an open cam lobe 16 and a close cam lobe 17; and two geared rockers, a open valve rocker 19 and a close valve rocker 20. A valve stem retainer assembly 12 is required to always engage the valve during operation. Positive force from the lobes of the overhead 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 17 is providing the force to close the valve then the open valve cam lobe 16 is not engaged with the cam. Likewise, if the open valve cam lobe 16 is actively driving the roller on the open valve rocker 19, then the close valve cam lobe 17 is not engaged. Since the open and close valve rockers are geared and engaged into each other, the rocker that is not driving the system at any given time, is being driven by it.

摘要： 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.
摘要翻译：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。

摘要： A mechanism for controlling the duration of the opening of the intake valve of an internal combustion engine which includes a split cam having a first lobe which is fixed to a primary cam shaft that is drivingly connected to the engine's crankshaft and a second lobe which is freely mounted to the primary cam shaft and which is driven by gears of an auxiliary cam shaft which is axially shiftable, or a segment thereof shiftable, to rotate the second cam lobe relative to the first lobe of the split cam to thereby change the angular relationship between the first and second lobes to advance or retard the closing of the intake valve.

摘要： An engine valve driving mechanism includes a cam having a tubular wall rotatable about a horizontal axis. A cam follower contacts both the inner and outer surfaces of the tubular cam wall, so that the follower is positively driven toward and away from the axis of rotation of the cam. The follower is connected to a valve stem mounted for motion in a direction perpendicular to the axis of rotation of the cam so that the motion of the cam follower enables the cam to positively and accurately drive the valve. The peripheral wall may be differently shaped in cross-section at different axial locations to provide different patterns of valve stem motion, and the cam is movable along its axis of rotation to permit selection of a desired pattern.

摘要： The first of a pair scissor like rocker arms is pivotally mounted at one end either by way of an adjust screw or a hydraulic lash adjuster and arangement to engage the top of a valve stem at the other. A cam follower which is located between the first and second ends engages a lift cam. The second of the rocker arms is pivotally mounted on the first one and has a closure cam follower at one end and engages the lower face of a retainer which secured to the top of the valve stem by way of a ring type collet. The shaft on which the second rocker arm is pivotally mounted can be provided with eccentric portions which enable the second rocker arm valve clearances to be adjusted separately from the adjustment of the first rocker arm clearance. The arrangement can be adapted to lift and close two valves.

摘要： 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.

摘要： 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.

摘要： A rotary valve with an axially extending passage revolves in a bed of a valve bearing body which has inlet passage means and a fluid transfer channel. The valve controls the periodic flow of fluid from the inlet means to the transfer channel. Fluid pressure containing pockets are provided diametrically of the transfer channel to let the rotary valve member float between opposed pressure fields. Accessary means can be provided to the rotary valve to secure equal forces at equal times on diametrically opposed portions of the outer face of the rotary valve member.
