摘要： A core of a solenoid actuator is provided which is improved in durability and at the same time ensures high energy efficiency of the solenoid actuator. The core of the solenoid actuator attracts an armature during operation of the solenoid actuator. A plurality of core plates are formed of a magnetically soft material and laminated in a predetermined direction orthogonal to a direction of attracting the armature to form a laminated stack. The core plates form magnetic circuits between the armature and the core plates themselves during the operation of the solenoid actuator. Two core holders formed of a non-magnetic material sandwiches the laminated stack of the plurality of core plates from opposite sides along the predetermined direction. The plurality of core plates are each coated with insulating film, which insulate adjacent two core plates from each other. Further, a rod formed of a non-magnetic material rigidly secures the plurality of core plates and the two core holders to each other to form a unitary assembly.

摘要： A main journal 25a of a crank-shaped swinging shaft 25 which swings in a range of a predetermined angle is supported by bearing metals 51 and 52 each divided into two pieces. In supplying a lubrication oil through an oil bore 51b in the bearing metal 51 to a sliding surface of the main journal 25a and to inlet openings of lubrication oil passages P1 and P2 of the swinging shaft 25 open to the sliding surface, the inlet openings of the lubrication oil passages P1 and P2 of the swinging shaft 25 are designed so that they do not move past division portions 55 of the bearing metals 51 and 52 upon swing of the swinging shaft 25 in the range of the predetermined angle. Therefore, it is possible to prevent the lubrication oil to be supplied to the lubrication oil passages P1 and P2 from leaking from the division portions 55 of the bearing metals 51 and 52, thereby reliably lubricating a pin journal 25b of the swinging shaft 25 by the lubrication oil supplied from the lubrication oil passages P1 and P2.

In each electromagnet, a coil is inserted between inner and outer yokes which are disposed in the form of a double-cylinder such that they open at their ends opposed to the armature and are magnetically coupled to each other at their ends opposite from the armature, and the coil is positioned so that the coil protrudes from at least one of the yokes toward the armature. The armature has an annular accommodating portion provided in a surface thereof opposed to each the electromagnets and capable of accommodating that portion of the coil which protrudes from the yoke. With such a structure, it is possible to increase the electromagnetic attracting force of each of the electromagnets and to enhance the performance of the engine.

摘要： A valve operating system in an internal combustion engine which provides a stable seating force for an engine valve and includes an armature operatively connected to a stem of the engine valve that is capable of being seated on a valve seat member provided to a cylinder head, valve-opening and valve-closing electromagnets for exhibiting electromagnetic forces for attracting the armature to open and close the engine valve, respectively, and valve-opening and valve-closing resilient means for exhibiting resilient forces for biasing the engine valve in opening and closing directions, respectively, and for retaining the armature in a predetermined neutral position by cooperation with each other during deenergization of both the valve-opening and valve-closing electromagnets. When the engine valve V is closed by energizing the valve-closing electromagnet and is seated on the valve seat member, only the resilient force of the valve-closing resilient means is applied to the engine valve V because the valve-closing electromagnet attracts the armature and compresses the valve-opening resilient means.
