    摘要: A hydraulic tensioning device (1) for a flexible drive element, particularly for a chain or a belt, is provided, and includes a housing (2) that has a cylindrical inner surface (3) at least in some regions, a piston (4) is arranged in the housing (2) in an axially displaceable manner, and an inner chamber (5) is formed by the housing (2) and the piston (4) for receiving hydraulic fluid. At least one vent hole (6) is integrated in the housing (2) and/or in the piston (4) is in contact with the surroundings (U). In order to provide a reliably ventilated system that has a simple design and that can be implemented in a cost-effective manner, a sealing element (7) is arranged in a region of the vent hole (6), and the sealing element is permeable to gas but not to hydraulic fluid.

    摘要: A hydraulic tensioning device is provided for a traction mechanism drive, in particular for a chain or belt drive of an internal combustion engine. The device includes a tensioning piston which is guided in a displaceable manner in a cylinder, with a pressure chamber being defined between the tensioning piston and the cylinder which is used to receive hydraulic fluid. A pressure relief valve is provided which limits the pressure in the pressure chamber. The pressure relief valve (8) includes, at least partially, a pre-assembled assembly (10) which can be inserted or is inserted into the tensioning piston (4).

    摘要: The invention relates to a tensioning system (8) of a traction mechanism (1) to which a hydraulic fluid is applied and which interacts with a tensioning rail (6). The design of the tensioning system (8) provides that in the operating state hydraulic fluid is fed to the traction means (2) and/or the tensioning rail (6) via a transverse groove (18) which is located in the region of an attachment screw (15) and has an end-side spray nozzle (22).

    摘要: In an internal combustion engine, a shaft driving apparatus and timing assembly in the form of a camshaft sprocket having first and second ends extending perpendicular to the axis of rotation. The first end for defining an annular timing surface positioned adjacent an angular position sensor and including a first arcuate surface region extending outwardly in the axial direction from the sprocket's first end and a second surface arcuate region recessed in the axial direction with respect to the first arcuate surface region. As the camshaft rotates, the closeness of the position sensor to the first arcuate surface region and the relative greater distance of the sensor to the second arcuate surface region produces different effects so that the sensor can detect the camshaft's angular position.

    摘要: An anode arrangement used in electrolytic processes for steel strip galvanizing or chrome-plating has a plate-like anode of titanium with an active surface, which is connected to a generally planar carrier having a steel core and a current supply conductor comprising a sleeve element and a bushing element. The core has a passage extending through it to receive the bushing element, and, for protection against attack by the electrolytic solution, the core is loosely surrounded by an envelope of titanium foil; in the region of the bushing element, the envelope has passages, the edges of which are welded to the bushing element in a gas-tight and fluid-tight manner.
