摘要： A hydraulic tensioning system (1), which is used in traction mechanism drives, particularly chain drives of internal combustion engines, is provided. The tensioning system (1) includes a piston (3), which is designed in the shape of a crucible, subjected to a pressure by a pressure spring (8), guided in a linearly displaceable manner in a housing (2) and spring-loaded against a traction mechanism. Hydraulic fluid can flow out of a pressure chamber (5) depending on an actuating direction of the piston (3) via an overpressure valve (11) forming a damping device (22) and associated with the piston (3) or can enter via a one-way valve (7) of the housing (2) into the pressure chamber (5). The overpressure valve (11) encloses a plate valve (21) that is integrated in the piston (3), and a pressure spring (8) of the piston (3) surrounds an outside of the valve housing (12) of the overpressure valve (11).

摘要： A method and device for the application of an elongated electric conductor to a solar element wherein the required length of the elongated electric conductor is readied and the conductor is strained through application of a tensile stress. The conductor is then fastened to the solar element. Straining of the elongated electric conductor is monitored to prevent exceeding of a tensile limit. During fastening onto the solar element at least one press-on roller is employed.

摘要： A chain tensioning device for use in a motor vehicle with a cylinder-piston unit (10) that has a piston housing (11) and a tensioning piston (12) that is provided for tensioning a chain and is arranged at least partially in the piston housing (11). A chain tensioner housing (13) is provided for establishing a flow connection between the cylinder-piston unit (10) and an operating medium circuit and holds at least partially the cylinder-piston unit (10). A compression joint fixes the piston housing (11) and the chain tensioner housing (13) against each other at least in the axial direction. The compression joint is constructed as a press fit by which the piston housing (11) and the chain tensioner housing (13) are directly connected to each other with a friction fit.
