摘要： In a vane-type camshaft phaser, one vane extends over a much larger internal angle than the other two vanes. Because of its size and strength, the large vane is the vane designated for contact with the stator. The other vanes and lobes have extra clearance to prevent contact regardless of rotor position. In one embodiment, a first surface of the large vane engages a surface of a first adjacent lobe at one extreme rotor rotation, and a second surface of the large vane engages a surface of a second adjacent lobe at the opposite extreme of rotation. The contact surfaces of the lobes and the vane may be equipped with hardened wear pads. One or more wear pads may be machined to provide a desired rotor displacement angle.

摘要： In a first embodiment of a camshaft phaser, the rotor is split along an equatorial plane thereof, defining first and second rotor portions. A resilient seal is compressively disposed between the rotor portions to prevent leakage therebetween and to urge the rotor vanes against the cover plate and sprocket surfaces to prevent leakage around the vanes. Preferably, the seal includes radial seal elements to seal against the stator wall. Preferably, pressurized hydraulic fluid can enter between the first and second rotor portions and thereby assist the resilient seal in urging the rotor portions apart. In a second embodiment, the rotor is not split, and a resilient seal is provided on at least one axial face of the rotor vanes to seal the rotor vanes against the cover plate and sprocket surfaces.

摘要： A lifter oil manifold assembly for variable actuation of engine valves having first (top) and second (valve) plates having portions of oil control and oil exhaust passages formed therein. The assembly further includes a carrier member having an oil supply passage integrated thereby separating the oil supply path from the oil control and oil exhaust path. Further, the assembly includes towers for receiving and positioning the electro-magnetic oil control valves used to control oil flow in the assembly. The towers are molded separate from the carrier and are held in place by the valve plate or are molded integral with the carrier. In another aspect of the invention, oil control valve retention springs are molded integral with either the tower or the oil control valve. In a further aspect of the invention, a combined polymer restrictor/strainer in the oil circuit replaces a prior art metal die-cast restrictor.

摘要： An improved splined cam phaser includes four assemblies: a sprocket assembly, an inner hub assembly, a cover assembly, and a piston assembly. The joined assemblies provide phaser function at reduced manufacturing cost. The component parts of the assemblies are re-configured from analogous parts in the prior art cam phaser to permit much of the improved phaser to be manufactured inexpensively by powdered metal forming or by stamping or drawing from sheet metal, in contrast with the prior art phaser wherein all parts are formed expensively either by machining from forged blanks or by investment casting. These changes reduce not only the cost of manufacture but also reduce the weight and axial length of the phaser, an important customer acceptance criterion, and improve the speed of response. Further, the proportions of some parts are altered such that all radial and axial loads are borne by a single large bearing in place of two small sequential bearings in the prior art phaser, thus reducing variability in axial alignment of the component parts.
摘要翻译：改进的花键凸轮移相器包括四个组件：链轮组件，内毂组件，盖组件和活塞组件。连接的组件以降低的制造成本提供相位器功能。组件的组成部分由现有技术的凸轮相位器中的类似部件重新构成，以允许大量改进的相位器通过粉末金属成形或通过冲压或拉制从金属板而廉价地制造，与现有技术的相位器其中所有零件都是通过从锻造坯料或熔模铸造加工形成的。这些变化不仅降低了制造成本，而且降低了移相器的重量和轴向长度，重要的客户接受标准，并提高了响应速度。此外，一些部件的比例被改变，使得所有的径向和轴向载荷代替现有技术的相位器中的两个小的顺序轴承由单个大的轴承承担，从而减少了部件的轴向对准的可变性。

摘要： An improved immersible magnetically-coupled mixer has a plurality of rollable bearing assemblies readily cleanable by flushing in place and easily removable and replaceable without damage to either the mixer impeller or the bearings. The rollable bearings are resistant to corrosion, capable of running without lubrication, and have low propensity for batch contamination through wear. The rolling and fixed elements of the bearings are impervious to attack by the process materials being mixed, the rollable elements, preferably balls, can be formed of a hybrid ceramic such as silicon nitride, and the races can be formed of a nickel-beryllium or cobalt-chromium-tungsten alloy. A mixer impeller having a central bore is rotatably mounted at the upper end of the bore on the rollable bearings on an adapter collar receivable over an end of a fixed impeller shaft attached to the inner wall of a vessel at the bottom of the mixing space, which shaft may be on existing mixer shaft, thus requiring no modification of the shaft to retrofit the impeller assembly. The impeller contains magnets and is couplable in driving relationship to an external magnetic mixer drive. The bearings are exposed to the liquid in the vessel during agitation, and the impeller provides a continual flow of liquid across the bearing balls and races and the adapter collar, preventing formation of stagnant areas of process materials within the mixer assembly and permitting cleaning of all mixer surfaces by flushing.

摘要： An improved lifter-oil manifold assembly (LOMA) for variable actuation of combustion valves in an internal combustion engine, comprising a body formed preferably of first and second plates having portions of oil flow passages integrally molded therein. A plurality of individual solenoid-actuated oil control valves is retained by a retainer in sockets formed in the plates.

摘要： A target wheel for a camshaft phaser stamped and drawn from sheet metal stock. The hub region of the target wheel may be drawn such that it extends through the phaser cover plate and seals directly against the face of the rotor, allowing a shorter cam bolt and resulting in reduction in mass and cost of the phaser. Alternatively, a separate hub is formed and then attached to a simplified stamped and drawn target wheel, or a target wheel hub is formed integrally with the rotor and extends through the cover plate to mate with a simplified stamped and drawn target wheel. Preferably, the hub is formed having a neck extending through a central opening in the target wheel, which neck is peened over during assembly to secure the wheel to the hub.

摘要： A target wheel/rotor pre-assembly for a camshaft phaser. A phaser rotor includes a central bore. A target wheel axial extension having a plurality of barbs is entered into the bore to fix the target wheel to the rotor, both axially and rotationally, prior to assembly of the rotor into a phaser stator during manufacture of the phaser. Simple gauge blocks or a fixture can be used to index the target wheel to the rotor such that all such rotor/wheel subassemblies are substantially identical, to a high degree of precision. Alternatively, the axial extension may be formed without barbs, the extension inserted into the rotor bore, and then the extension immobilized as by stamping of the barbs, tack welding, or the like. For another example, the axial extension may be formed as a separate intermediate barbed retainer that engages both the rotor bore and the target wheel.

摘要： A fast-acting rotor-locking mechanism for a vane-type camshaft phaser. A straight-sided locking pin is disposed in a bushing in the rotor and is urged into a sprocket well by a return spring. A pad disposed at the bottom of the well is a travel stop for the pin. When the pin is fully seated against the pad, the pad covers a portion of the end of the pin. The uncovered portion of the pin end, exposed to oil pressure for unlocking the pin when it is fully seated, is decreased over the prior art pin, permitting use of a lighter locking spring having a lower spring rate. Because of the lighter locking spring, the pin accelerates more rapidly and unlocks significantly faster than in a comparable prior art phaser.

摘要： An improved releasable and reusable self-sealing plug for mechanically sealing a bore. A cylindrical body is formed on its outer surface to retain radial sealing means such as an O-ring. An oversize annular cap at the outer end of the body limits ingress of the plug into a bore, and a pair of opposed, flexible limbs terminating in flanges beyond the inner end of the body are compressed radially during insertion of the plug and spring out at completion of insertion to grip the inner entrance to the bore, thus holding the O-ring and plug in the bore. Insertion may be accomplished manually without the aid of tools. The plug cannot be driven out by pressure on the bore, but is easily removed by recompression of the limbs and flanges and withdrawal of the plug by, for example, needle-nose pliers. The plug may be formed inexpensively and easily by injection molding of a suitable plastic polymer.
