摘要
Device for the relative angular adjustment between at least two shafts that are arranged between each other in a drive connection, especially on a crankshaft and at least one camshaft; in this case, the camshaft has, through its drive end, a regulation element that at this same end can be moved axially and which is connected to this shaft, in a form-driven manner, through an inclined toothing; this regulating element is connected by means of another inclined toothing, in a form-fitting manner and axially movable, with a hollow cylindrical shaft that surrounds the same element and that supports a drive wheel; in this case, the regulation element is provided with a hydraulic conveyor cylinder that is arranged within an annular chamber that is constituted by the hollow shaft and by that end of the camshaft, which is located next to the drive; This hydraulic conveyor cylinder divides the annular chamber into two working chambers, and it can be displaced for the purpose of adjusting the drive wheel with respect to the camshaft as well as by means of pressure oil from the lubricating oil circuit. of an internal combustion engine, which depending on the position of a distribution element is supplied to a first working chamber (16) from a first position to a second position, being able to be controlled by the distribution element that stops the pressure oil control is equipped with an oil groove that works in conjunction with two oil supply bores (30, 32) and with two oil returns (30, 33) arranged at that end of the camshaft, which The pressure oil is located next to the discharge through an oil return to the lubrication oil circuit; This device is characterized in that the positioning of the hydraulic transporter cylinder (6) from the second position to the first position is also carried out by the oil under pressure, which is supplied to the second working chamber (16) by the distribution element (17). ; because the distribution surfaces of the distribution piston (17), which are arranged on both sides of the oil groove (18), are made in such a way that the return of the oil from the respective working chamber (15 or 16 ), which is under pressure, is blocked, while the oil return from the respective non-pressure working chamber (16 or 15) is open; as well as characterized in that the circumferential oil groove (18) of the distribution piston (17) has between its distribution edges (41, 42) a width that is greater than the distance between the distribution edges opposite each other (43, 44 ) from the oil supply holes (30, 32) to the first and to the second working chamber (16 and 15, respectively).
