20090031974 | Electromechanical camshaft phaser having a worm gear drive with a hypoid gear actuator - An electromechanical camshaft phasing system comprising a first pinion gear mounted on the end of an engine camshaft and engaged by a worm gear mounted on a transverse shaft extending from and journalled by bearings in a phaser drive sprocket to cause the camshaft to rotate in response to the engine crankshaft. The first pinion gear is surrounded by a ring gear having a hub keyed to an armature or stator shaft of a motor mounted on the engine coaxially of the camshaft and first pinion gear. A second pinion gear mounted on the worm gear shaft engages the ring gear such that motor rotation of the ring gear about the first pinion gear causes rotation of the second pinion gear, worm gear, first pinion gear, and thus the camshaft with respect to the sprocket, thus varying the phase of the camshaft with respect to the crankshaft. | 02-05-2009 |
20090044770 | Camshaft phaser wiper seal with integral spring - A wiper seal for preventing leakage of oil between advance and retard chambers formed between rotor vanes and stator lobes in a vane-type camshaft phaser is a monolithic structure made from a single material that includes a wiper element and a compressible spring element extending from the wiper element. The spring element is designed as a cantilevered arm and provides a sealing pressure to the wiper element. The wiper seal may further include a rib element as part of the monolithic structure that vertically extends the wiper element towards the spring element. The rib element assists in preventing over-compression of the cantilevered arm and in preventing tangling of a plurality of wiper seals during handling and shipping. The wiper seal is provided at the tip of each rotor vane and/or stator lobe of a vane-type camshaft phaser for varying the timing of combustion valves in an internal combustion engine. | 02-19-2009 |
20100064996 | Cam phaser helical bias spring having a square end for retention - A helical phaser bias spring including at least one linear region and an adjacent region having a radius of curvature less than that of the helix.

Preferably, the spring includes two linear regions separated by a bend of about 90°. Additional linear regions are possible, separated by right and/or other angle bends. In a phaser rotor or stator, the geometric shape required to hold a spring end having a flat is easier to form with powdered metal tooling or diecasting than is a circular, radial, or axial shape for receiving a spring tang as in the prior art, the packaging volume required for the spring is smaller, and spring friction is lowered. | 03-18-2010 |
