Abstract: A valve-lift device for the variable control of gas-exchange valves of an internal combustion engine is provided. The device includes a pivotable lever that is capable of being driven by a camshaft, the pivotable lever having an axis of rotation which can be displaced in a slotted-link track fixed to the housing, and a valve actuation means. The pivotable lever has, at one end, a roller which is driven by a camshaft and, at its other end, a slotted-link roller which is moved along a working curve in a slotted link, the slotted link being designed as an engagement surface of a valve actuation means. A center of rotation of the lever is provided between the roller and the slotted-link roller and the center of rotation of the rocker lever and a supporting axis of the valve actuation means is arranged on a vertical axis in an operating position. In order to set a valve lift, an axis of rotation is displaced in a slotted-link track fixed to the housing.

Abstract: A valve pause mechanism of a four-stroke internal combustion engine includes a valve pause mechanism. A valve lifter fitted between a valve cam and a valve stem of a poppet valve is always pressed in a direction in which the valve lifter contacts the valve cam with a lifter spring. However, a slide pin is fitted into a slide pin holder fitted in the valve lifter so that a slide pin can slide in a direction perpendicular to the valve stem. A stem working face in contact with the valve stem of the poppet valve and a stem through hole that the valve stem pierces are both adjacently formed in the slide pin and a slide pin driving mechanism. The slide pin driving mechanism selectively makes the stem working face and the stem through hole face the valve stem by moving the slide pin. A side of the slide pin at the back of the stem working face is chamfered across the stem through hole. A plane perpendicular to the central axis of the stem through hole is formed in a chamfered part and its both ends in a direction of the central axis of the slide pin continue to the peripheral surface of the slide pin in a smooth curve. The aforementioned arrangement provides a valve pause mechanism with a durable, relatively light slide pin.

Abstract: A four-cycle engine includes a cylinder block defining a cylinder bore. A piston is reciprocally disposed within the cylinder bore. A cylinder head member closes an end of the cylinder bore to define a combustion chamber together with the cylinder bore and the piston. The cylinder head member defines an inner passage having a first end communicating with the combustion chamber and a second end terminating at an outer surface of the cylinder head. A valve assembly having a valve section and an actuateable section is provided. The valve section is selectively placed at an open position and a closed position to connect and disconnect the inner passage with the combustion chamber, respectively. The actuateable section is formed oppositely from the valve section. A valve actuation mechanism is arranged to actuate the actuateable section to move the valve section between the open position and the closed position. The cylinder head member further defines a guide opening through which the actuateable section is slideably disposed. An external conduit defines an outer passage communicating with the inner passage. The external conduit depends from an end portion of the cylinder head member. The cylinder head member still further defines a recessed portion between the guide opening and the second end of the inner passage.

Abstract: A camshaft lash adjustment process for an internal combustion engine includes the steps of substituting a tiltable camshaft retainer for a camshaft bearing cap which is proximate a driven end of the camshaft, followed by removal of all remaining camshaft bearing caps and the substitution of a camshaft tilt limiter for one of the camshaft bearing caps so as to allow rotation of the camshaft to a tilted position. This permits adjustment of valve tappets driven by the camshaft.

Abstract: Upper and lower contact discs (5, 6) are used for adjusting valve clearance with a mechanical cup tappet (1). The lower contact discs (6) have a substantially larger clearance adjusting range H.sub.SW than the upper contact discs (5). In this way, the invention succeeds in further reducing the total mass of the cup tappet (1) because, in an initial mounting of the cup tappet (1), the valve clearance is adjusted through the relatively small lower contact disc (6) and thus with relatively small mass fluctuations.

Abstract: A shim for a tappet is used in a valve operating mechanism in an internal combustion engine. On the surface of the shim which a cam slidably contacts, there are provided a number of bores in which lubricating oil is put. When an oil film disappears on the surface by slidable contact with the cam, oil overflows from the bores onto the surface. By increasing oil-keeping capability on the surface of the shim, frictional resistance is reduced, thereby preventing wear in the shim and the cam. The bores may be filled with a lubricating solid such as molybdenum disulfide or plastics, such as polyethylene, silicone and Teflon.RTM.. The diameter of the bores may become larger as the bores extend away from the surface of the shim, thereby preventing the solid material from being displaced from the bores. The density of the bores on the shim surface can also be varied. The density of the bores in the central area of the shim surface can be greater than in the surrounding area.

Abstract: A tappet and shim assembly is disclosed for operating directly between a valve and a camshaft lobe in an internal combustion engine. The assembly comprises a tappet having a shallow cylindrical recess in one end that is concentric with an outer cylindrical surface of the tappet. A dual-diameter cylindrical shim is provided with concentric small and large diameter cylindrical portions wherein the large cylindrical portion has a diameter that is sufficiently large so that a flat end surface thereof contacts with a lobe of a camshaft without the lobe contacting the edge of this surface. The small diameter portion of the shim is received in the recess of the tappet and the diameter of the outer cylindrical surface of the latter is made just slightly larger than that of the large diameter portion of the shim so that the latter is received with clearance in the bore in which the tappet is received. The small diameter portion of the shim is provided with an axial dimension such that when it is bottomed out in the recess in the tappet, the large diameter portion of the shim is located at a distance from the tappet to form an annular space therebetween for insertion of a sharp tipped tool to remove the shim from the tappet.

Abstract: A valve lifter of a valve mechanism for an internal combustion engine is provided with a crown-shaped valve lifter body which has a center plate with a recess. A fixing projection is integrally formed with the center plate and is formed along a side wall which defines the recess. An inner shim of a disc shape has a plurality of grooves to which the fixing projection is filled by caulking the fixing projection for fixedly connecting the inner shim with the valve lifter body. Therefore, the inner shim is easily and securely assembled in the recess of the valve lifter body so as not to generate the looseness between the inner shim and the valve lifter body while the assemble performance is improved.

Abstract: A shim attaching/detaching tool for a tappet of an internal combustion engine includes as essential components an air supplying tube, an air blowing tube and a nozzle formed at an opening portion of the air blowing tube at the foremost end of the same. When compressed air is blown from the nozzle toward the shim while the air supplying tube is inclined at an angle of about 45 degrees and the nozzle is oriented toward the fitting portion of the shim fitted into a circular cavity, the shim is thrusted against the opposite side of the cavity and the compressed air is then introduced into the space below the shim through the gap appearing around the fitting portion of the shim, whereby the shim is floated up away from the cavity so as to enable it to be easily exchanged with another shim having a different thickness.
