    • Engine valve driving apparatus including a camshaft rotatable with a crankshaft of the engine with a movable cam member supported in sliding fit by the camshaft for axial movement but prevented from any rotation relative to the camshaft. An engine valve is driven by the movable cam member, and a hydraulic system axially shifts the movable cam member between an operative position where the movable cam member is brought into cooperation with the engine valve and an inoperative position where the movable cam member is completely out of cooperation with the engine valve. The hydraulic system causes the shifting movement of the movable cam member according to engine operating conditions so that the engine valve is driven at different speeds or different timings.

    • A dual induction type intake system for an internal combustion engine has a primary intake passageway for light load operation of the engine and a secondary intake passageway for heavy load operation of the engine. The downstream side open end of each intake passageway opens toward the intake port of the cylinder of the engine. The secondary intake passageway is provided with a controllable valve therein. The load on the engine is detected and the controllable valve is opened when the load on the engine is heavier than a predetermined value so that the intake gas is introduced into the combustion chamber through both the primary and secondary intake passageways, while otherwise the controllable valve is closed so that the intake gas is introduced into the combustion chamber only through the primary intake passageway. The primary intake passageway has a flat cross sectional configuration with its longer axis extending substantially in parallel to the lower end surface of the cylinder head, and at the same time the primary intake passageway is throated by narrowing its width, as measured in the horizontal direction, from upstream toward downstream in the direction of the flow of the intake gas. The downstream side open end of the primary intake passageway is offset from the center of the cylinder bore.
    • 用于内燃机的双感应式进气系统具有用于发动机的轻负载运行的主进气通道和用于发动机的重负载运行的二次进气通道。 每个进气通道的下游侧开口端朝向发动机气缸的进气口开口。 次级进气通道在其中设置有可控阀。 检测到发动机上的负载,并且当发动机上的负载比预定值重时,可控阀打开,使得进气通过主进气通道和次级进气通道被引入燃烧室,否则可控阀 被关闭,使得仅通过主进气通道将进气引入燃烧室。 主进气通道具有扁平的横截面形状,其长轴基本上平行于气缸盖的下端表面延伸,并且同时通过使水平方向测量的主要进气通道变窄而使主入口通道变窄 ,从进气的流动方向的上游向下游。 主进气通道的下游侧开口端偏离气缸孔的中心。

    • An adjuster has a cylindrical shape and is rotatably supported in a housing of a fastener-driving tool about an axis parallel to one direction. The adjuster has an outer circumferential surface provided with one of a first recessed portion and a first protruding portion. A bumper is movable in the one direction and another direction opposite the one direction according to a rotation of the adjuster. An urging member has one of a second recessed portion and a second protruding portion. One of the second recessed portion and the second protruding portion is constantly in contact with the outer circumferential surface and is engaged with the one of the first recessed portion and the first protruding portion.
    • 调节器具有圆柱形形状并且围绕平行于一个方向的轴线可旋转地支撑在紧固件驱动工具的壳体中。 调节器具有设置有第一凹部和第一突出部中的一个的外周面。 保险杠可以根据调节器的旋转沿一个方向和与一个方向相反的另一个方向移动。 推动构件具有第二凹部和第二突出部中的一个。 第二凹部和第二突出部中的一个与外周面不断地接触并与第一凹部和第一突出部中的一个接合。

    • A fastener driving tool providing a prolonged durability and stabilized fastener driving operation. The tool includes a housing 2, a motor 31 disposed in the housing 2, a plunger 63 disposed in the housing and driven by the motor 31 for driving a nail 1A, a cable member 52 connected to the plunger 63 for pulling the plunger 63 from its bottom dead center where the nail is driven into a workpiece to a top dead center, and a drum 51 driven by the motor for winding the cable member thereover. A cable member is wound over the drum by a length greater than a linear distance between the bottom dead center and the top dead center. The cable member is flexed or deflected due to own weight when the plunger is at the bottom dead center.
