Abstract: In a tightening device for a drive belt in an internal combustion engine, particularly for a toothed belt in the camshaft gear with a tension roller supported on a pivoting lever comprising a tension spring acting upon the pivoting lever in the direction of tension and a blocking device opposing the motion of the pivoting lever, whose blocking element changes its position as a function of the temperature, the blocking element formed as an end stop by the free end (17) of a preferably plate shaped stop body (18) whose other end (19) is held in a fixed housing (1) wherein the end stop in the operating state of the internal combustion engine is disposed at a distance from the adjacent support face of the pivoting lever. The tightening device with the thermally adjustable end stop avoids a tooth jump, particularly in the case of long belts.

Abstract: An adjustable timing gear arrangement having an output shaft and a camshaft operable in timed relationship with the output shaft comprises a first rotatable drive member driven by the output shaft with a second rotatable drive member mounted on the camshaft and operably connected with the first drive member for rotation in timed relation therewith. The second drive member is mounted on the camshaft for rotation on a common axis with the second drive member and the camshaft and is secured thereto to fix the angular relationship of the members. The mounting permits limited relative angular rotation of the members when the members are not so secured. For adjusting the relative angular positions of the second drive member and the camshaft there is an assembly including an unthreaded, cylindrical stud extending from the camshaft into a radially extending slotted opening through the second drive member. The opening includes angularly spaced, parallel sides. An eccentric cam is freely rotatable on the cylindrical stud and closely fits between the parallel sides of the slotted opening. A tool receiving portion on the cam is arranged for permitting selected rotation of the cam to cause relative angular adjustment of the second drive member relative to the camshaft. The slotted opening and the eccentric cam have cooperating interengaging portions lying in a plane perpendicular to the axis of rotation of the camshaft for retaining the cam in the slotted opening while permitting free rotation of the cam relative to the second drive member.

Abstract: A V-type internal-combustion engine has two banks of cylinders, each with a cylinder-head housing which is covered by cylinder-head cover and, on each end face, by an end cover. Camshafts are driven via chain wheels by a common chain which is led through a free space between the two banks of cylinders in a well housing. To reduce jumps in sealing surfaces which present sealing problems, the well housing is arranged at a distance from the parting planes between the cylinder-head housings and cylinder-head covers and is fastened solely between the cylinder-head housings and the end covers.

Abstract: An internal-combustion engine has a camshaft drive in which the outlet camshaft driven by the crankshaft drives the inlet camshaft via a chain. For the tensioning of the chain, two hydraulic pistons are pressed in opposite directions with respect to one another against the loose end and the load end of the interior side of the chain. For adjustment of the relative camshaft rotating position, the unit consisting of the hydraulic piston and the chain is shifted transversely to the camshafts so that the loose end is shortened and the load end is lengthened, or vice versa.

Abstract: The chain for transmitting the drive between two overhead camshafts of a combustion engine for motor vehicles has an associated tensioning device comprising a rod-like support body fixed to the head in a position offset from the plane of the chain and a bush which can slide coaxially on the rod and is formed with a bracket carrying a shoe in sliding pressure contact with a free pass of the chain. The tensioning device incorporates means for automatically taking up the play between the shoe and the chain, including frictional axial positioning means between the bush and the rod for enabling the braked sliding of the former relative to the latter under the action of resilient and hydraulic thrust means.

Abstract: An OHC vertical crankshaft engine, comprising: a vertically disposed crankshaft having a first timing pulley at its lower end; a cooling fan attached to an upper end of the crankshaft; a camshaft extending in parallel with the crankshaft at a cylinder head end of the engine and having a second timing pulley at its lower end; and a timing belt passed around the timing pulleys. Thus, the need for lubrication for the transmission mechanism between the crankshaft and the camshaft is substantially eliminated, and the noise generation is reduced. Additionally, since the upper part of the cylinder head is directly exposed to the cooling air produced by a fan provided at an upper end of the crankshaft, a high engine cooling efficiency can be achieved. This effect is even more enhanced if the exhaust port of the engine is disposed above the intake port and extends horizontally and linearly away from the engine.
