摘要： It is proposed to lessen the weight and improve the mechanical strength of a retainer of a valve open-close mechanism driven by an electromagnetic actuator used in an automotive internal combustion engine. The electromagnetic actuator is mounted in a housing mounted on an internal combustion engine body. A first stem has its tip abutting the valve, which is provided with a retainer and carries a first coil spring. A second stem is provided on the other side of an armature. The second stem has a retainer. Between this retainer and the housing, a second coil spring is mounted. At least one of these parts is made of a metal smaller in specific weight than iron or its alloy. Each retainer has a boss and an arcuate corner portion having a radius of curvature R of 1.0 mm or over between a spring abutting surface and the boss to relieve stress concentration.

摘要： In a combination of the shim 5 and cam 1 for use in a reciprocating mechanism portion, the shim 5 is made of a material having a hardness higher than that of the sliding surface of the cam 1 and the sliding surface of the shim 5 is finished to within a range of the surface roughness of Rz0.07-0.2 &mgr;m in 10-point mean surface roughness and further the sliding surface of the cam 1 is provided with open pores 1b. In the above combination, the generated torque and the wear of sliding portion are minimized by selecting a shim member whose surface roughness is difficult to deteriorate due to plastic deformation by a injection pump contact with a mating member and corrosion by various impurities mixed in lubricant and the like, and providing the surface of a cam member with an oil film holding function so as to maintain fluid lubrication of the sliding surface.

摘要： There are provided a dust core in which, even if the surface of a heat-treated compact is ground, the insulation between soft magnetic particles on the ground surface can be ensured in the grinding step, and a method for producing the dust core.The method includes a preparation step of preparing a heat-treated compact 100 by compacting soft magnetic particles having an insulation coating and heating the resultant compact to a predetermined temperature; and a machining step of removing part of the heat-treated compact 100 using a working tool 2. The machining step is performed while an electric current is supplied with a conductive fluid 7L between the heat-treated compact 100 serving as an anode and a working tool 2 that machines the heat-treated compact 100 or a first counter electrode 5 that faces the working tool 2 with a distance therebetween, the working tool 2 or the first counter electrode 5 serving as a cathode. A bridge portion that connects soft magnetic particles to each other is removed through the supply of an electric current, the soft magnetic particles being adjacent to each other along a machined surface of the heat-treated compact 100.

摘要： An attachment coupler includes a first arm and a second arm, each including a U-shaped portion, and upper portions of the first and second arms being swingably connected by a swing shaft, and an expansion-contraction tool which opens and closes the first and second arms around the swing shaft as a fulcrum. A locking member provided with a cam and a hook provided with a cam follower are rotatably provided on the second arm. A state in which a free end of the hook is removed from an opening of the U-shaped portion is maintained by engagement of the cam and the cam follower during contraction of the expansion-contraction tool. The cam follower is driven by the cam along with rotation of the locking member during expansion of the expansion-contraction tool, thereby causing the free end of the hook to advance toward the opening of the U-shaped portion.

摘要： To lighten the weight of an electromagnetic actuator and a valve-open-close mechanism by forming the stems from a lighter material than conventional. A pair of electromagnets formed of stators and coils are opposed to each other with a gap therebetween. An armature is disposed in the gap so as to be reciprocable between one electromagnet and the other electromagnet by the electromagnets. A first stem for transmitting the movement of the armature from one electromagnet toward the other electromagnet to a valve of the internal combustion engine is inserted in a guide hole formed in the stator of one electromagnet. The first stem is formed of a lighter material than the armature to lighten the weight of the electromagnetic actuator and a valve-open-close mechanism of an internal combustion engine.
