摘要： A length-adjustable connecting rod for an internal combustion engine, where the connecting rod includes at least one switchable outlet valve for opening and closing a pressure chamber, where the outlet valve comprises a valve body and a closing body that is operatively connected to the valve body, and a closing mechanism is present acting upon the closing body for directly moving the closing body and indirectly moving the valve body from a closed to an open position or vice versa. Such an outlet valve is to be configured to be operable. For this purpose, this closing body has a mass which is smaller than the volume defined by the envelope contour of the closing body multiplied by the density of steel (7.85 g/mm3). The use of such a closing body for a respective length-adjustable connecting rod is also provided.

摘要： A longitudinally adjustable connecting rod for a piston engine, where the connecting rod includes a first connecting rod end for receiving a piston pin and a second connecting rod end for receiving a crankshaft journal, where the distance between the piston pin and the crankshaft journal is adjustable in the longitudinal direction (A) of the connecting rod by way of a hydraulic control device with a hydraulic control valve. The hydraulic control valve comprises a control cylinder and a control slide which is guided in a slidable manner in the control cylinder and which can be pressurized, and at least one outlet valve which can be actuated by the control slide. The control slide comprises a control piston which is arranged on the end face, with a control pressure surface which can be subjected to the hydraulic control pressure and which defines a control pressure chamber in the control cylinder. The use of such a longitudinally adjustable connecting rod with a hydraulic control device in a piston engine as well as a corresponding piston engine is also provided.

摘要： A length-adjustable connecting rod for an internal combustion engine, comprises a first connecting rod member, a second connecting rod member and at least one cylinder-piston assembly for adjusting the first connecting rod member relative to the second connecting rod member. The cylinder-piston assembly can be actuated by way of a hydraulic adjustment mechanism, where the hydraulic adjustment mechanism comprises at least one oil filter in order to filter the engine oil of the internal combustion engine flowing into the cylinder-piston assembly. The invention further relates to an internal combustion engine with such a length-adjustable connecting rod and the use of such a cylinder-piston assembly for a length-adjustable connecting rod of an internal combustion engine.

摘要： A link chain has alternating inner and outer chain links connected by a chain articulation, having a direction of motion, wherein each inner chain link has at least one inner plate, and each outer chain link has at least two outer plates and two chain link pins connecting these plates, each pin being rotationally fixed in a pin opening of the associated outer plate and extending through a link opening of the associated inner chain link to form a chain articulation. The inner and/or outer chain links have plate backs contactable with a tensioning rail or guide rail. A forward region of the plate backs in the direction of motion of a part of the inner and/or outer plates extends at an angle to a plane projected between the center lines of the pin openings or link openings. The vertex of the angle points away from the direction of motion.

摘要： A method for producing high-performance chain link plates with a link plate pitch T, comprises: clocked feeding of a sheet metal band with a feed length V per cycle, pre-punching at least two chain link plate blanks arranged in succession, re-cutting at least one chain link plate blank, wherein at least the still connected head areas of the chain link plate blanks arranged in succession are excepted from the re-cutting process separating the connected head areas of chain link plate blanks arranged in succession, wherein the feed length V is smaller than 2.1×T and the upper and/or lower side of the head areas connected to each other is/are provided at least partially with a concave run by a punching process substantially adjacent to the end face produced later. A method is also provided for producing a high-performance chain and to correspondingly produced high-performance link plates and high-performance chain.
