The invention relates to an internal combustion engine fit-up device, according to which each intake manifold is arranged at a level lower than that of the associated cylinder head, a walkway is mounted above each intake manifold, and the engine pipes are mounted in the space between the said walkway and the said intake manifold.

Internal combustion engine fit-up device

An integrally moulded overhead valve chest for an internal combustion engine, comprising a cage having several arms and formed with an annular valve seat cooling chamber and a valve stem guide formed with an annular guide cooling chamber which communicates with said seat cooling chamber through at least one duct formed within one arm, wherein the improvement consists in at least one hole extending through the radially outer wall of one of said cooling chambers and stopped or closed off by a welded or brazed plug.

Cooled integral valve chest for an internal combustion engine and method

A variable displacement pump, the delivery of which is controlled through the medium of a toothed rack meshing with a pinion through which the piston of the pump is adapted to slide axially, said piston being adapted to rotate jointly with said pinion and to move in translation jointly with pump actuation means, and the toothed rack meshing with an auxiliary shaft pinion the angular position of which is located by an indicating needle, thus ensuring a measurement of the delivery of said pump.

Device for locating the position of the control rack of a pump and for

Method for removing a valve mounted in an internal combustion engine cylinder-head, and valve actuating device allowing to carry out said method which comprises the steps of increasing the clearance between the valve rod and the corresponding end of its rocker arm, shifting laterally the corresponding push-rod for allowing the end of the rocker arm to be withdrawn from the removal path of the valve, and removing the valve upwardly.

Method of removing a valve mounted in an internal combustion engine

An overhead valve chest for an internal combustion engine with a cylindroconical portion adjacent to the bottom seating of the chest within the cylinder-head and comprising a sealing ring overlapping said cylindro-conical portion and mounted in a groove the diameter of the flat horizontal top wall of which adjacent to the conical portion of said chest is larger than that of the lower wall opposite to the cylindrical wall of said chest, said ring being in continuous bearing engagement with its ends inside of said groove.
