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 valve system for an engine including a valve resting mechanism provided between an engine valve and a valve lifter supported by a cylinder head. The valve resting mechanism can place the engine valve into a resting state. The valve resting mechanism has a pin holder which includes a sliding hole having an axis perpendicular to the axis of a valve lifter, and an insertion hole for allowing a valve stem to pass therethrough. The pin holder is slidably fitted in the valve lifter. A slide pin is slidably fitted in the sliding hole, with a hydraulic force and a spring force applied to both ends of the slide pin. A containing hole is coaxially connectable to the insertion hole, and a rotation stopping means for stopping axial rotation of the slide pin is provided between the pin holder and the slide pin.
