  • Patent number: 7066123
    Abstract: An intake or exhaust valve for an internal combustion engine has a rocker arm with a pivot between its ends, one end of which is engaged by the pushrod, and the other end engages the valve stem. An adjustable stop has two positions for the rocker arm pivot; a rest position where there is no movement of the pivot, and an upper lock position where the pivot moves in response to the pushrod, and there is a reduction in the opening of the valve. A progressive rate spring compresses as the pivot moves towards the upper lock position, thereby modulating valve opening for relatively slow start (or stop) of valve stroke with accelerating (or decelerating stroke), as the progressive rate spring compresses (or expands). Relatively thinner and thicker Belleville springs are used in series to produce a progressive rate spring. The lock position of the pivot elevated above the rest position is determined by a hydraulic block trapping oil in a closed chamber.
