Abstract: The device according to the invention for storing electrical energy comprises at least one galvanic cell. The same is at least partially surrounded by a casing. Furthermore, the device comprises a cell holding unit comprising an internal space. The at least one galvanic cell is arranged in the internal space. Furthermore, the cell holding unit comprises a wall, which at least partially delimits said internal space. Therein, the wall of the cell holding unit and/or the at least one galvanic cell comprise at least one hollow space. The at least one hollow space is at least partially filled with a first heat conducting means.

Abstract: An accumulator comprises at least one galvanic cell and a receiving device for supporting the galvanic cell(s) of the accumulator. The receiving device comprises at least one protecting wall for receiving energy by means of elastic and/or plastic deformation. The protecting wall encases the at least one galvanic cell at least partially and has a thickness which is at least partially less than about 1/10 of the characteristic edge length of the at least one galvanic cell. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: The invention relates to a tensioner (1, 1?, 1?) for a traction means such as a belt, a chain or the like, having a tensioning lever (2) which is in operative connection with a helical spring (32) and is pivotable about a fixed axis (20) and on which a receptacle (21) for a tensioning element for bearing against the traction means to be tensioned is arranged, the helical spring (32) being held at its ends by spring receptacles (30, 31; 30?, 31?; 30?, 31?). It is proposed that the helical spring (32) be screwed to at least one of the spring receptacles (30, 31; 30?, 31?; 30?, 31?). This construction ensures that a reliable and easy-to-assemble connection between the helical spring (32) and the spring receptacle (30, 31) is achieved at this point.

Abstract: A tensioner for a traction member includes a faceplate that is stationarily secured to a machine part, with a working eccentric member rotatably supported on the faceplate for limited rotation against a spring force. After pre-installation of the tensioner, a locking device fixes the position of the working eccentric member relative to the faceplate. In one installation position, a catch limits the pivot range of the working eccentric member.
