摘要： A valve moving apparatus of an internal combustion engine has an intake camshaft with an intake variable cam piece for opening and closing an intake valve, and an exhaust camshaft with an exhaust variable cam piece for opening and closing an exhaust valve. Each variable cam piece has a low speed cam section and a high speed cam section and is movable axially relatively to the camshaft. A hydraulic driving mechanism is provided for moving the variable cam piece axially in accordance with engine operation condition. The driving mechanism has a driving piston and arms touching both sides of the variable cam piece. When valve operating characteristic of the intake valve or the exhaust valve is changed corresponding to engine operation condition, response is improved. The engine can be miniaturized.

摘要： A pair of link arms each supported at one end thereof on an engine body for swinging movement about an axis parallel to a rotational axis for a valve-operating cam are connected at the other ends, for relative turning movement about an axis parallel to the rotational axis, directly to a rocker arm having a valve abutment abutting against an engine valve and a cam abutment contacting with the valve-operating cam. At least any one of the link arms is swingably supported at one end thereof on the engine body for continuous movement within a plane perpendicular to a rotational axis for the valve-operating cam. Such an arrangement ensures that a valve-operating system can be constructed compactly, and the opening lift amount of the engine valve can be changed continuously, while ensuring an excellent followability to the valve-operating cam.

摘要： In a valve operating system in an internal combustion engine, a swinging support section provided at a base end of a rocker arm is swingably carried on a rocker shaft mounted in a cylinder head. A plurality of valve abutments are provided at a tip end of the rocker arm and capable of being individually put into abutment against upper ends of a plurality of engine valves, and a cam abutment is provided on the rocker arm in an intermediate portion between the swinging support section and each of the valve abutments to come into contact with a valve operating cam. The swinging support section comprises a thinner cylindrical portion surrounding the rocker shaft, and thicker cylindrical portions which are formed at a thickness larger than that of the thinner cylindrical portion into a cylindrical shape to surround the rocker shaft and which are integrally and continuously provided at axially opposite ends of the thinner cylindrical portion, respectively. Thus, it is possible to enhance the durability of the rocker arm, while avoiding an increase in weight of the rocker arm.

摘要： One of adjacent rocker arms in a valve operating system of an engine is provided with first and second support walls. A roller is disposed between the first and second support walls to come into rolling contact with cams. A cylindrical roller shaft, supporting the roller, is provided between the first and second support walls, so that a switchover pin of an associative-operation switchover means can be slidably fitted into the roller shaft in response to the movement thereof. The roller shaft is press-fitted into at least a second one of the first and second support walls, and a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the other rocker arm is set smaller than a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the roller.

摘要： A lens position detecting device comprises at least two columns of contacts each having a plurality of contacts, the columns being disposed side by side, and a brush having a plurality of brush segments each for contacting the contacts of the corresponding one of the columns and detecting a voltage at a contact thereof. Each contact of one column is shifted by a predetermined amount from the contacts of an adjacent column. The voltage at one contact is different from that at another contact of the same column, and these different voltages detectable at the contacts of one column constitute the same group as for the other columns. The lens position is determined depending on the combination of at least two voltages detected through the brush segments. The lens positions are thus divisible into a greater number of increments at the same time that the device is composed of a smaller number of elements.

Cam abutments are provided on the rocker arm in an intermediate portion between the swinging support section and the boss portions to come into contact with a valve operating cam. The boss portions are interconnected by a connection wall having a plurality of wall portions which intersect each other in a plane perpendicular to the axis of the rocker shaft. Thus, the rigidity of the tip end of the rocker arm is enhanced sufficiently.

摘要： A valve operating system in an internal combustion engine includes an associative-operation switchover means capable of switching over the associative operation of a pair of rocker arms disposed adjacent each other and the releasing of the associative-operation. The associative-operation switchover means is provided between a plurality of rocker arms including the rocker arms disposed adjacent each other. In such valve operating system, through-bores are coaxially provided in support walls of the rocker arm, and opposite ends of a roller shaft are fitted and fixed in the through-bores. A spring-receiving member is mounted to the roller shaft for receiving a return spring. Thus, when the roller shaft with the return spring of the associative-operation switchover means accommodated therein is mounted to the rocker arm, it is possible to facilitate the processing and to reduce the size and weight of the rocker arm.
