An exhaust-gas recirculation (EGR) valve includes a rotary drive. The rotary drive includes a cam member that has a cam profile. The rotary drive permits operation of a valve member that can be rotated around a rotational shaft. During the course of a closing movement, the EGR valve can, toward the end of the closing movement, move towards a valve seat in a direction that is generally parallel to a direction of flow through the valve seat.

A stick-type ignition coil have a central core, a cylindrical member, primary spool, primary coil, secondary spool, secondary coil, outer core and a resin insulator. The two longitudinal end corners and faces of the core are covered by respective buffer members. The inner circumferential corners of the outer core is supported by ring members. Some of the members disposed radially inside and other members disposed radially outside of the inside members are held slidably to each other in the ignition coil. The spools are made of resin containing a rubber in excess of 5 weight percent and reinforcing materials. The resin insulator contains a flexible material.

A continuously variable electrical actuator rotationally coupled to and thermally isolated from a butterfly valve. The butterfly valve may be used to modulate high temperature exhaust gas flow through an engine turbocharger. An electrical actuator provides a continuously variable output to an output shaft. The butterfly valve has its rotary position controlled by an input shaft. The input shaft and output shaft are rotationally coupled through minimum contact points to reduce heat transfer. The connection between input and output shafts also minimizes vibration transfer therebetween. An coupling tube coaxially interposed between the input and output shafts provides a thermal block to further reduce heat transfer. The input and outputs shafts are rotationally coupled to the intermediate shaft by torsion spring mechanisms to allow a limited range of axial translation for the input shaft. The torsion spring mechanisms are preloaded to prevent rotational hysteresis in the butterfly valve.

PURPOSE:To make it possible to mount a permanent magnet in an ignition coil for an internal combustion engine, in which the permanent magnet is interposed between magnetic circuits, easily and at low cost and at the same time, to ensure the stable ignition of the ignition coil CONSTITUTION:Magnetic circuits are formed of cores 2 and 3, which are respectively wound with a primary coil 12 and a secondary coil 22, and a permanent magnet 5 is interposed between these magnetic circuits This magnet 5 is magnetized after a resin molding is performed and is formed of a magnet material maintaining a prescribed magnetic force into a prescribed form of such a thickness as to allow a mold manufacture For example, the magnet 5 is formed of a 1-5 samarium-cobalt magnet material into a rectangular plate body having a thickness of 15mm or thicker and after the resin molding is performed, the magnet 5 is magnetized Thereby, when the permanent magnet is manufactured by a metal mold, it is never broken and after the resin molding is performed including the permanent magnet, the magnet 5 can be easily magnetized

Ignition coil for internal combustion engine

An exhaust gas flow control valve for an internal combustion engine comprises a body, a diaphragm actuator and a bracket. The body is equipped with an exhaust passage and a valve member arranged in the exhaust passage. The bracket is equipped with an actuator mounting seat for mounting the diaphragm actuator and a body mounting seat connected to the body. The diaphragm actuator is equipped with a casing connected to the actuator mounting seat of the bracket, a diaphragm cased in the casing and a rod protruding from the diaphragm and out of the casing for actuating the valve member in accordance with the action of the diaphragm. Between the actuator mounting seat of the bracket and the diaphragm of the diaphragm actuator, moreover, there is formed an insulating layer for insulating the heat to be transferred to the diaphragm.

PROBLEM TO BE SOLVED: To suitably adjust the output of an accelerator sensor, and to relatively decrease variations of a terminal position and kick-down position of a pedal lever. SOLUTION: The pedal lever 2 is turnably supported by a supporting frame 3 between a rest position and a terminal position. The pedal lever 2 is returned to the rest position by return springs 5A, 5B. The accelerator sensor 4 detects a turning position of the pedal lever 2. A kick-down mechanism 6 adds abrupt tread force to the pedal lever 2 at the kick-down position near the terminal position. The kick-down mechanism 6 is integrally provided with an adjusting bolt 26 for adjusting the terminal position. While the pedal lever 2 is positioned at the terminal position, the terminal position is adjusted by the adjusting bolt 26. After adjusting the terminal position of the pedal lever 2, a resisting element 13 provided on a base plate 12 is trimmed, thereby the output of the accelerator sensor 4 is adjusted.
