A compression ring of a chain sprocket is provided with improved wear characteristics and damping to match various forms of link plates of a chain assembly. The chain assembly includes a plurality of longitudinal link plates hingedly connected by a plurality of pins. The compression ring includes two arrays of compression pads, each array defined by a different profile. Each array of compression pads can be matched to two corresponding groups of link plates. Multiple forms of compression pads and link plate geometries can be accommodated. Compression pad damping force can be tuned by adjusting the width and/or height of the link plates.

The invention relates to an overpressure valve () which is in the form of a one-way valve or a check valve and which includes a pot-shaped housing () with a base () and central opening () and which also has a valve seat () which interacts with a spring-loaded closing body (). A guide sleeve () is inserted with a force fit or form fit into the housing () for the purpose of receiving a compression spring () which exerts a load on the closing body (), which guide sleeve simultaneously ensures a construction of the overpressure valve () which is secured against falling apart.

A tensioning device for an endless traction element in an engine. The tensioning device has a housing, a plunger, which can he moved in the housing, a compression spring arranged in the plunger, a nonreturn valve arranged between the plunger and the housing, a cylinder arranged in the plunger, and an engagement element. The plunger and the cylinder are connected to one another by a latching system via engagement of the engagement element, and the cylinder is connected materially to the nonreturn valve.

A traction engine drive (), the components of which are integrated into an assembly unit () that can be pre-completed. A guide rail () having a clamp rail () is fixed in location by a clamping device () and a traction element () is disposed in conjunction with at least one traction mechanism wheel, so that a free length of the traction element is not present.
