Abstract: A bi-directional dual coil half bridge converter adapted to be coupled to a dual coil actuator of a cylinder valve in an internal combustion engine is described. In one example, the converter has a first and second capacitor and a voltage source, where the converter is actuated via switches to individually energizing coils in said dual coil actuator. A voltage regulator is also shown for maintaining midpoint voltage during unequal loading of different actuator coils in the converter.

Abstract: A hollow step-profiled shaft such as a cam shaft that is high in accuracy and excellent in productivity and requires little post-machining is being formed. To this end, a hollow stepped shaft 8 having its axis and large diameter portions 9a-12b intermediate axially between its ends is formed by a forming process in which each large diameter portion of the shaft is compressed with forming dies 32a-32d from at least three different directions approximately simultaneously towards the axis to shape the large diameter portion with a profile such as to conform to contours 38a-38d of a cavity 38 formed in a region of tips of the forming dies 32a-32d.

The aim of the invention is to enable one such device to be reliably controlled. To this end, the control cam (5) has a catch region (5a), and the intermediate member (4) is mounted on a bearing having an axis which corresponds to the rotational axis (7), said bearing being arranged in such a way that it is guided in a forced manner and can be displaced parallel to the curve of displacement (8, 28, 35), by means of an articulation (16, 24, 26) connected to the cylinder head or the housing or by a slide (34) that is guided in the housing in a positively locking manner. The invention also relates to a method for operating an internal combustion engine comprising a plurality of cylinders using at least one of the inventive devices.

Abstract: Camshaft adjusters which work in accordance with the operating principle of a hydraulic oscillating motor comprise at least two components arranged parallel to one another. Frequently, the two components are a covering plate and a stator. The two components are connected by fasteners which penetrate through one of the two components. At least one of the fasteners is equipped with a central, deformable pin which, in the obstructed state, impedes the nondestructive separation of the two components arranged parallel to one another.

Abstract: A variable stroke valve drive for an internal combustion engine, including an intermediate lever which is slidingly arranged on a crank path of a crank arm the intermediate lever has a working cam with null lifting cam and lifting cam portions. The working cam contacts a gas exchange valve via an intermediate element. A first adjustment element rotates the intermediate lever against a spring element around a point located near the crank, the intermediate lever being displaceable along the crank path by a second adjustment element. The first adjustment element is provided with a cam plate whose radius continuously increases or reduces on a circumference with respect to an axis of rotation. The inventive variable stroke valve drive substantially reduces wear in a valve drive.

Abstract: A valve-operating system for an internal combustion engine includes cam followers which have cam abutment portions abutting against valve-operating cams provided on a camshaft and which are swingably carried in an engine body and operatively connected to engine valves biased in a closing direction by a valve spring. The cam followers are biased in a direction of abutment of the cam abutment portions against the valve-operating cams by a resilient biasing means different from the valve spring. A resilient biasing means includes a pull rod connected at one end thereof to the cam follower, and a compression coil spring interposed between the other end of the pull rod and the engine body to pull the pull rod to bias the cam follower in a direction of abutment of the cam abutment portion against the valve-operating cam. Thus, the resilient biasing means is constructed to be compact, leading to an increase in degree of freedom of the design of the structure of the valve-operating system.
