摘要： Valve lift mechanism for an engine includes a two step variable valve lifter having roller followers for engaging multiple cams on an associated camshaft of the engine and an anti-rotation guide mounted in the engine externally of a cylindrical bore receiving the lifter. The guide engages an axial guide recess in the lifter body without requiring a corresponding recess in the bore. The lifter also has a saddle in a central low lift cam follower engagable by lock pins in an annular body of an associated high lift cam follower to lock the followers together for high valve lift operation. The saddle is disposed axially between a follower roller and a high pressure chamber of a hydraulic lash adjuster of the low lift cam follower so that lock pin loads are transmitted as compressive forces through the low lift follower. The high lift follower rollers are received in pockets having sides that are crowned by shallow convex curvatures defining axially extending ridges which limit axial motion of the rollers so that the rubbing surface and associated friction are limited. Various additional specific features are disclosed. Application of the features to other valve lifters and cam followers is anticipated.
摘要翻译： 用于发动机的气门升程机构包括两级可变气门升降器，其具有用于接合发动机的相关凸轮轴上的多个凸轮的滚子跟随器，以及安装在发动机外部的反转引导件，所述反转引导件在接收升降器的圆柱形孔的外部。 引导件与升降机主体中的轴向引导凹部接合，而不需要在孔中相应的凹槽。 升降机还具有在中央低升程凸轮从动件中的鞍座，其通过相关联的高升程凸轮从动件的环形体中的锁定销接合，以将跟随器锁定在一起用于高气门升程操作。 鞍座轴向地布置在低升程凸轮从动件的液压间隙调节器的从动辊和高压室之间，使得锁定销负载作为压力通过低升程从动件传递。 高升降从动辊被容纳在具有限定轴向延伸的脊的浅凸曲率的顶部的凹部中，该凹凸限制了辊的轴向运动，使得摩擦表面和相关联的摩擦受到限制。 公开了各种附加的特定特征。 预期将特征应用于其他气门挺杆和凸轮从动件。

摘要： An axially-compact camshaft phaser wherein the phaser bearing flange on the camshaft, connected to a timing chain sprocket or cam drive gear, is axially inverted in comparison to prior art cam phasers so that the bearing flange extends axially and inwardly of the phaser stator and rotor such that radial drive load on the phaser is sustained within the hydraulic portion of the phaser rather than externally thereof. The overall axial length of the phaser may be reduced thereby by about 25% relative to some prior art phasers and the Phaser Envelop volume may be reduced by 15% while maintaining an equivalent torque capacity.

摘要： A camshaft phaser includes a housing with a harmonic gear drive unit disposed therein. The harmonic gear drive unit includes a circular spline and a dynamic spline, a flexspline disposed radially within the circular spline and the dynamic spline, a wave generator disposed radially within the flexspline, and a rotational actuator connectable to the wave generator. One of the circular spline and the dynamic spline is fixed to the housing. A hub is rotatably disposed radially within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. An anti-rotation means is provided for temporarily fixing the circular spline to the dynamic spline in order to prevent relative rotation therebetween when the hub is being attached to the camshaft. The anti-rotation means prevents damage to the harmonic gear drive unit while the camshaft phaser is being installed onto the camshaft.

摘要： A modular vane cam phaser assembly for controllably and continuously varying the rotational phase between a camshaft and the crankshaft of a reciprocating internal combustion engine. The module includes a housing mountable to the front of an engine head, the housing supporting on an outer surface thereof a programmably-controllable spool valve for directing pressurized oil to an oil commutator extending into both the housing and a vane phaser wherein a rotor is bolted to the camshaft and a stator is bolted to a timing sprocket. The oil is distributed by the spool valve to opposite sides of the rotor vanes in response to signals generated by an induction cam rotation sensor and by other engine components and processed by a powertrain control module to advance or retard the opening of intake and/or exhaust valves in the engine. The housing is provided with internal passages for supplying oil from an engine port to the spool valve. Preferably, the oil is filtered by a thimble screen as it enters the housing.

摘要： A vane-type camshaft phaser wherein a coil spring under torsional compression or extension is disposed coaxially within an annular cavity formed in either the cover plate or back plate. A first end of the spring is connected to the cover plate or back plate, and a second end extends from the cavity and is connected to the phaser rotor. The spring constant is selected such that a biasing torque is exerted on the rotor in the valve-opening-advancing direction which counters the inherent valve-opening-retarding torque bias of the camshaft during operation. The bias spring permits more rapid response to a demand on the cam phaser for advancing valve timing, and is also useful in orienting the camshaft advantageously, especially an exhaust valve camshaft, in a timing-advanced position when the engine is shut off or operating at low engine speed.
