    Abstract: A system for controlling the timing of poppet-type intake and/or exhaust valves in internal combustion engines of the four-cycle spark or compression ignition and two-cycle compression ignition type that may be normally aspirated, supercharged or turbocharged, wherein the timing is adjusted automatically or manually in relation to the speed of the engine to obtain optimum efficiency at any given speed. Dual camshafts are utilized, one for opening the valves, and one for closing the valves. An adjustable timing mechanism between the crankshaft and the camshafts simultaneously adjusts the opening and closing cycles of the valves.

    Abstract: The valve operating apparatus includes an upper and lower rocker arm for each valve to be controlled, each having a straight section and a curved section. The lower rocker arm is mounted at one end for pivotal movement about a fixed axis, its other end acting against the valve to be controlled. The upper rocker arm is mounted at one end for pivotal movement about a shiftable or movable axis. Depending on where the upper rocker arm has been shifted to in relation to the camshaft and concomitantly where the upper arm has been shifted in relation to the lower arm the lift and duration of valve opening is controlled. A timing mechanism is actuated by the valve operating apparatus so as to angularly displace the camshaft on which the above alluded to cam is mounted in a direction to advance or retard the valve opening and closing with respect to the crankshaft and hence in relation to the piston movement produced by the crankshaft.

    Abstract: A device for feed control of valve-controlled internal combustion engines, with the combustion chamber capable of being closed off by an intake valve toward the intake passage, and with a further shutoff element being provided in the intake passage. This further shutoff element is a slotted flat slide valve which is movable in an oscillating manner and cooperates with counter slots. The counter slots are formed by vanes arranged in the housing. The flat slide valve is drivable by a cam.

    Abstract: An internal combustion engine includes a cylinder head, a support structure, a cam pulley, and a seal member. The support structure is provided above the cylinder head and supports the camshaft. The cam pulley is provided at an end of the camshaft. A timing belt is wound around the cam pulley. A seal member is provided to cover a gap provided between the cylinder head and the support structure at a facing surface facing the cam pulley. The seal member provides sealing between the cylinder head and the support structure in an axial direction of the camshaft.

    Abstract: An endless band drive system having a variable center distance between the drive pulley and the driven pulley also has a rotatable control shaft and an endless band guide, where the guide is positioned by the rotatable control shaft for maintaining a slackless endless band with change of pulley center distance. Rotation of the control shaft pivots the endless band guide thereby maintaining a slackless endless band with change of the pulley center distance. Preferably, the rotatable control shaft also provides means for adjusting the center distance between the drive pulley and the driven pulley. The present invention provides a slackless endless band system for a variable compression ratio engine having a variable center distance between the drive pulley mounted on the crankshaft and the driven pulley mounted on the camshaft. The system provides slackless operation of the endless band at two or more compression ratio values.

    Abstract: A product for applying tension is disclosed. A block may have a first passage opening into the block. A body may have a first manifold and may be positioned against the block so that the first passage is open to the first manifold. The body may have a flow path for providing fluid from the first manifold to a second manifold and there through to a pressure chamber. The flow path may include a series of channels and may be configured to allow substantially unimpeded flow from the first manifold to the second manifold, and to impede flow from the second manifold to the first manifold. The flow path may be free of movable components.

    Abstract: A housing is rotatable synchronously with a crankshaft of an engine. A plurality of external teeth arrangements is respectively shaped into a ring form and is formed integrally with the housing in one piece and is configured to mesh with a plurality of chains, respectively, each of which is wound around the crankshaft or a sprocket that is rotatable. A cam plate is connected to a camshaft of the engine and is rotatable relative to the housing. A plurality of stoppers is formed integrally with the housing in one piece while the stoppers are configured to limit relative rotation between the housing and the cam plate within a predetermined range when the stoppers contact the cam plate. Each stopper is placed at a position, at which the stopper does not overlap with any of the external teeth arrangements in a view taken in an axial direction of the housing.
