    Abstract: A camshaft adjuster mounted between a taut strand and a slack strand of a chain connecting an intake camshaft to an exhaust camshaft has two tensioning shoes which are urged by a spring away from each other and against the inner sides of the chain strands. One tensioning shoe is mounted on a reciprocable piston within which a plunger carrying the other tensioning shoe is slidable against the force of the spring. The piston is moved against the taut strand by pressurization of a pressure chamber through a nonreturn valve and the plunger is moved with the piston so that the taut and slack strands are moved together and compression of the tensioning spring is thereby maintained relatively constant. A damping chamber may be provided with throttling bores in the piston and/or plunger to control the damping effect.

    Abstract: In a valve operating system for an internal combustion engine comprising a valve-operation driving force transmission means interposed between a valve operating camshaft and an engine valve carried in a body of the internal combustion engine for opening and closing operation of the engine valve, a valve operation mode changeover mechanism capable of switching the opening and closing mode of the engine valve in accordance with the operating condition of the engine, and a wrapping connector type transmission system provided between the valve operating camshaft and a crankshaft, the valve operating system further includes a tension adjusting means capable of adjusting the tension of a transmitting band of the wrapping connector type transmission system, and a control means for controlling the operation of the tension adjusting means in accordance with the operation mode of the valve operation mode changeover mechanism. It is possible to vary the preset load of the transmitting band in accordance with the operation of the valve operation mode changeover mechanism to vary the peak value of the load applied from the valve operating camshaft to the transmitting band, thereby adjusting the tension of the transmitting band in accordance with the change in operation mode of the engine valve.

    Abstract: The angular timing relationship of the cams opening and closing the inlet and exhaust valves of an internal combustion engine can be varied while the engine is running to improve combustion efficiency. The angular relationship is varied by shifting of idler rollers 78, 80 acting on the camshaft driving timing chain adjusted by providing two cams 108, 110 for the same valve intake 104 so that cam 108 controls opening and cam 110 controls closing. Exhaust valve 105 has its opening controlled by cam 115 and its closing controlled by cam 113. An idler 122 between the two camshafts controlling cams 110 and 115 acts on the timing chain. The timing is also varied by moving the pivot point 104 of the rocker arm 62 to obtain later closing of the inlet and earlier opening of the exhaust valve 46 at high speed. Valve timing and duration is also controlled by adjusting the length of the push rod 108 and its point of contact with rocker arm 62.

    Abstract: A timing belt drive system for driving the camshafts in internal-combustion engines which provides control of the valve timing and overlap. Slack is provided in the timing belt, and is taken up by movable idler pulleys. The positions of the centers of the idlers are displaceable under external control, as in response to engine speed and intake vacuum. Displacement of the idlers thus operates to change the angular relation between the drive pulley on the crankshaft and the driven pulley on the camshaft, i.e., the valve timing. In dohc engines having separate camshafts for the intake and exhaust valves, the valve ''''overlap'''' is similarly controllable. The system provides higher efficiency over a wider range of speeds, and reduces the emission of pollutants.

    Abstract: A variable valve timing assembly includes an electric motor; a first set of gears driven by the electric motor; a first set of grooves and ball bearings driven by the first set of gears; a second set of grooves and ball bearings driven by the first of grooves and ball bearings; wherein the first set of grooves and ball bearings converts rotational movement of the first set of gears to axial rotational movement of the first set of ball bearings; wherein the axial movement of the first set of ball bearings causes rotational movement of the second set of grooves; whereby the rotational movement of the second set of grooves enables rotation of a camshaft engaged to a valve.

    Abstract: A camshaft phaser is provided that includes a stator, a rotor having a plurality of vanes that form fluid chambers with the stator, and a timing wheel attached to the rotor via a spline joint arranged between the rotor and timing wheel. The spline joint is configured to prevent axial and radial movement of the timing wheel relative to the rotor.
