    摘要: In a VVA apparatus for an internal combustion engine wherein the position of contact of a cam face of a VO cam with respect to the top face of a valve lifter is changed in accordance with a change in a rocking fulcrum of a rocker arm to alter the valve lift, the maximum valve lift is obtained in a first rotated position of a control shaft where an axis of a control cam is adjacent to a driving shaft. The minimum valve lift is obtained in a second rotated position of the control shaft where the axis of the control cam is positioned near a first pivotal point of the rocker arm and a crank arm with respect to a first line connecting the axis of the control shaft and the axis of the control cam upon the maximum valve lift.

    摘要: An electromagnetic drive system for repeatedly opening and closing a valve of an internal combustion engine is comprised of an electromagnetic drive mechanism and a damper mechanism. The electromagnetic drive mechanism comprises a pair of electromagnets, an armature disposed between the electromagnets and a pair of springs setting the armature at a neutral position between the electromagnets when both the electromagnets are de-energized. The electromagnets are alternately energized and de-energized according to a control signal. The damper mechanism is interlocked with the electromagnetic drive mechanism and functions to decrease a speed of displacement of the valve at a terminating period of each of a valve-closing stroke and a valve-opening stroke of the valve.

    摘要: An electromagnetic driving device of engine valve for internal combustion engine comprising an electromagnetic deriving mechanism includes a first and second electromagnets positioned opposite each other, an armature disposed in a gap formed between the electromagnets for moving therebetween, a follower having a first and second followers that are positioned opposite each other is for moving in relation to the armature, a valve associated with the armature for closing and opening an intake or exhaust passage, a first and second cams having gradually varied their profile are pivoted for contacting respective the first and second followers, a spring is disposed between the follower and the cams for urge the first and second cams toward the first and second followers, respectively. Thereby, the armature is prevented from colliding the electromagnet, and the valve capable of seating a valve seat smoothly and gently, so that the valve is possible to indicate an ideal valve lift characteristic at the end period of the valve. Therefore, this invention is possible to prevent noise, wearing and damage caused by the collision between the valve and the valve seat and between the armature and the electromagnet.

    摘要: A valve timing control apparatus is provided which comprises an intermediate rotary member rotatable relative to a driving rotary member and a driven rotary member and having a spiral guide of a single spiral. Rotation of the intermediate rotary member caused by a control force applying unit causes radial movement of the guided members which is in turn converted to relative rotation between the driving rotary member and the driven rotary member by the links. The spiral of the spiral guide is defined so that a rate of change of spiral radius per angle is not constant.

    摘要: An electrical pump apparatus is provided in which a situation where a failure detection circuit becomes inoperative before detection of a failure of an electric system can be avoided, and the certainty of failure detection can be enhanced. An attaching portion which is to be attached to a vehicle body is formed so that, in a state where an electrical pump apparatus is attached to the vehicle body, a circuit board of a control device is perpendicular to the horizontal direction. A control IC chip which constitutes a microcomputer for detecting a failure of the electric system is placed on a circuit board so as to be higher in the direction of gravity from a lowest water level Hmin at which flooding in a housing causes the electric system to be short-circuited.
