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.

摘要： A vane-type camshaft phaser includes a rotor having a plurality of vanes disposed in a stator having a plurality of lobes, the interspersion of vanes and lobes defining a plurality of alternating valve timing advance and valve timing retard chambers. Each vane and lobe tip is provided with an axially extending groove having an outward expansion of width. A wiper seal element, formed by stamping and folding from a single piece of sheet material, has folded wings that extend under compression into the groove. The spring loading of the wings against the tapered walls of the groove acts to urge the wiper seal element out of the groove and toward the opposing stator or rotor wall, thus ensuring a continuous forced sealing contact of the wiper seal element with the opposing wall and the groove walls during operation of the camshaft phaser.

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 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 cam phaser assembly having an improved configuration of the C1 oil gallery in the camshaft supplying oil to the cam phaser. An axial bore in the camshaft is formed over its non-threaded outer portion at a diameter substantially greater than the diameter of the bolt connecting the phaser to the camshaft. Upon assembly of the cam phaser to the camshaft, an annular, cylindrical gallery is formed between the bolt surface and the bore, which gallery replaces the plurality of axial bores required for the C1 gallery in the prior art camshaft. The prior art C2 gallery, which utilizes a second axial bore in the bolt itself, is substantially unchanged, and an O-ring around the cam bolt in the first axial bore seals the C1 and C2 pressure galleries from communicating with each other.

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.
