Abstract: A hydraulic tensioner is designed for low cost and ease of manufacturing. A housing has a bore and a sleeve member received within the bore. A piston is slidably received within the sleeve member, forming a high pressure fluid chamber with the sleeve member. The housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and sleeve member are constructed of drawn metal. The housing may be formed by injection molding. The sleeve member and other components of the tensioner may be assembled within the tensioner by inserting them into the mold during the injection molding process.

Abstract: A vibration damper assembly to absorb vibrations in a camshaft and sprocket system has a sprocket positioned around a camshaft, an inertia ring positioned around the camshaft and adjacent the sprocket, yet capable of moving independently of the sprocket, and a hub member positioned around the camshaft adjacent the inertia ring. Frictional material is interposed between the hub member and a rim portion of the inertia ring whereby the inertia ring and hub member slide with respect to one another along the frictional material to absorb vibrations from the camshaft through heat dissipation.

Abstract: A hydraulic tensioner with a sealing element to provide fluid leakage from a fluid filled chamber. The tensioner includes a housing having a fluid filled chamber and a hollow piston slidably received within the chamber and biased in a protruding direction by a spring. A sealing element is positioned in a groove in the piston or is mounted in the inner wall of the chamber. The sealing element is discontinuous so as to permit the passage of fluid from the fluid filled chamber to outside of the hydraulic tensioner. Fluid leakage is limited and controlled by discontinuity size of the sealing element.

Abstract: A control system for an adjustment device for a variable compression ratio engine comprising: a jack head, a jack piston, a sprocket wheel, a movable transmission member, and a control valve. The jack piston is received within a chamber of the jack head defining first and second fluid chambers. The control valve controls the flow of fluid between the first and second fluid chambers. Based on the position of the control valve, fluid flows from the first fluid chamber to the second fluid chamber or vice versa, moving the control rack connecting the jack piston to the sprocket wheel. Reciprocating motion of the sprocket wheel adjusts the position of the cylinder of the engine.

Abstract: A transmission for an engine or motor with a reduced package size and increased efficiency comprising: an input sprocket, an output sprocket, a chain, and a planetary gear set. The output sprocket is drivingly connecting to the input sprocket through the chain. The output sprocket has a hollow center portion that receives the sun gear of the planetary gear set. The planetary gear set also includes at least two planet gears meshed with the sun gear which are mounted to a fixed planet carrier for driving a differential with a ring gear portion. When the input sprocket is rotated in a first direction, the chain drives the output sprocket and the sun gear in the first direction, and the sun gear drives the planet gears to rotate in a second direction, opposite the first direction, driving the ring gear portion and differential in the second direction.

Abstract: A sprocket unit comprising: a damper mounted on the first shaft with a first face defining a recess and a second face defining chambers for receiving spring loaded weights; a sprocket mounted to the first shaft with a hub defining an aperture and a slot; a front end plate mounted on the shaft with a hub defining an aperture aligned with the aperture of the sprocket; and a spring received within the aperture of the sprocket, the aperture of the front end plate, and the recess of the damper. When the first shaft rotates and firing frequency of the engine coincides with a resonant frequency of the first shaft, the spring loaded weights slide in the chambers of the damper, dampening out the resonant frequency in the first shaft and when the sprocket rotates the spring compresses and extends, reducing torsional load of the first shaft on the second shaft.

Abstract: A variable camshaft timing phaser for an internal combustion engine having at least one camshaft comprising a plurality of vanes in chambers defined by a housing and a spool valve. The vanes define an advance and a retard chamber. At least one of the vanes is cam torque actuated (CTA) and at least one of the other vanes is oil pressure actuated (OPA). The spool valve is coupled to the advance and retard chamber defined by the CTA vane and the advance chamber defined by the OPA vane. When the phaser is in the advance position, fluid is routed from the retard chamber defined by the OPA vane to the retard chamber defined the CTA vane. When the phaser is in the retard position, fluid is routed from the retard chamber defined by the CTA vane to the advance chamber defined by the CTA vane.
