摘要： A valve timing adjuster according to the present invention, comprises a pulley rotationally connected to one of an output shaft of engine and a cam shaft, a sleeve which is supported on the pulley, which is rotatable within a predetermined angle of rotation on the pulley and which is rotationally connected to the other one of the output shaft of engine and the cam shaft, an electromagnet mounted on one of the pulley and the sleeve, an armature mounted on the other one of the pulley and the sleeve so that magnetic flux including a magnetic flux component extending in the circumferential direction of the valve timing adjuster is generated, the armature is drawn by the magnetic flux toward the electromagnet and the sleeve is rotated within the predetermined angle of rotation on the pulley when the electromagnet is energized, and a control device which controls the operation of electromagnet so that the phase difference between the cam shaft and the output shaft is suitably adjusted during operation of a vehicle. Since the valve timing adjuster according to the present invention does not need means for converting an axial movement of the pulley to a circumferential or rotational movement thereof, does not have many friction regions and does not have the hydraulically-operated actuator and the hydraulic pipe lines, the durability and response speed are increased and the cost of modification of engine is not needed.
摘要翻译：根据本发明的气门正时调节器包括一个可旋转地连接到发动机的输出轴和凸轮轴中的一个的滑轮，一个被支撑在滑轮上的套筒，该套筒可以在滑轮上的预定旋转角度内旋转，其旋转地连接到发动机的输出轴和凸轮轴中的另一个，安装在滑轮和套筒中的一个上的电磁体，安装在滑轮和套筒中的另一个上的电枢，使得包括一个产生在气门正时调节器的圆周方向上延伸的磁通量分量，当电磁铁通电时，电枢被磁通量吸引向电磁体并且套筒在滑轮上的预定旋转角度内旋转，并且控制控制电磁铁的操作的装置，使得凸轮轴和输出轴之间的相位差适当地调节车辆的运行。由于根据本发明的气门正时调节器不需要用于将滑轮的轴向运动转换成周向或旋转运动的装置，所以不具有许多摩擦区域，并且不具有液压操作的致动器和液压管路，耐久性和响应速度增加，并且不需要发动机的修改成本。

摘要： An engine exhaust gas purification system has a secondary air system for supplying secondary air into the engine exhaust system. The secondary air system has an air metering valve and a switching valve. The air metering valve is operative to meter the secondary air supply in accordance with signals emitted by an air-fuel ratio sensor disposed in the exhaust system to detect the oxygen content of engine exhaust gases. The switching valve is disposed in the secondary air supply line downstream of the air metering valve to interrupt the supply of the secondary air into the exhaust system during a high load engine operation for thereby preventing the exhaust system and, particularly, the catalyst device therein from being overheated. The force to close the switching valve is strong enough to keep the valve closed against the counter-flow of engine exhaust gases from engine exhaust system back into the secondary air system.
摘要翻译：发动机废气净化系统具有用于将二次空气供应到发动机排气系统中的二次空气系统。二次空气系统具有空气计量阀和切换阀。空气计量阀根据设置在排气系统中的空燃比传感器发出的信号来测量二次空气供应，以检测发动机废气的氧含量。切换阀设置在空气计量阀下游的二次空气供应管线中，以在高负荷发动机运转期间中断供应到排气系统的二次空气，从而防止排气系统，特别是其中的催化剂装置过热关闭切换阀的力足够强大，以保持阀门不受发动机排气系统的发动机排气逆流回二次空气系统的逆流。

摘要： An electrical connector device includes first and second cable winding members one of which is co-rotatable with a rotatable side and the other of which is fixed to a stationary side. The first and second cable winding members are arranged with their respective centers being spaced apart from each other. An flexible cable is fixed at its one end to the first cable winding member and at its other end to the second cable winding member. The flexible cable is wound around the first winding member to form a loose winding of a plurality of turns therearound so that relative rotation between the first and second cable winding members is allowed by means of radially expanding and contracting behavior of the cable winding around the first cable winding member.
