Abstract: The invention relates to a device for actuating a gas exchange valve for internal combustion engines, comprising an electromagnetic actuator which is float-mounted in a cylinder head, which is supported on a play compensation element and which has an opening magnet and a closing magnet. An armature is located between the pole faces of said magnets in such a way that that it can be axially displaced in relation to the valve axis. The electromagnetic actuator acts upon a valve shaft either directly or by means of an armature tappet. The inventive device also comprises one pre-stressed valve spring which acts upon the gas exchange valve in the opening direction and one pre-stressed valve spring which acts upon the same in the closing direction. Said springs are arranged between the actuator and the gas exchange valve and are supported with one end on the valve shaft or the armature tappet, via a spring plate. The valve spring which acts in the direction of opening is supported with its free end on the actuator. According to the invention, the valve spring which acts in the direction of closing is supported with its free end directly or indirectly on the actuator.

Abstract: PURPOSE:To make enough the wear resistance of an expansible/contractible rubber bag in the reservoir of a lash adjuster for the valve mechanism of an internal combustion engine, by making the bag of rubber mixed with Teflon at a prescribed ratio to increase the rigidity of the bag. CONSTITUTION:When the expansible/contractible part of a rubber bag 34 is expander or contracted, the tips 34c, 34d, 34e of the lower Y-shaped part of the bag act as fulcra and the rubber bag is rubbed on the inside part 20d of a plunger 20. Since the bag 34 is made of rubber mixed with 2 to 3wt% of Teflon, the wear resistance of the bag is high enough. When the presure of a pressure chamber 27 has become negative, a check ball 29 is separated from a valve seat 32 despite the tension of a spring 31 to suck oil from a reservoir 25. Even if the force of the suction acts, an oil passage is not shut off, because of the rigidity of the bottom of the rubber bag 34.

Abstract: A high-pressure oil pump roller tappet, used for automobile fuel injection system, mounted between the driving cam and the tappet. The roller tappet includes a shell, a holder, a roller, and a pin. Planes A are arranged on both sides of the seam on lateral sides of the shell. Holes I are arranged at symmetrical positions on two planes A. Holes II are arranged on symmetrical positions on vertical plates. The roller is located in the middle of the pin. Welding has no requirement on the thickness of the plate. The weight can be controlled effectively, reducing inertia force, friction, and wear, improving engine efficiency. The shell and holder are designed as being separate, ensuring that the shell subjects to lateral force as little as possible when the holder subjects to a force, such that the shell is less likely to vibrate. Thus, the shell avoids the abrasion.
