Abstract
The invention relates to an oscillating motor adjuster with a stator (1), a rotor (8) which is positioned within the stator (1) and is displaceable relative to the stator (1) on a first rotor connection (11) by hydraulic pressure in a first direction, and relative to the stator (1) on a second rotor connection (13) by hydraulic pressure in a second direction, a central valve (12) which projects through a hub (7) of the rotor (8) and is inserted into a camshaft (18), wherein the central valve (12) has a first working connection (A) and, at an axial distance from the first working connection (A), a second working connection (B), and wherein the first working connection (A) is connected to the first rotor connection (11) and the second working connection (B) to the second rotor connection (13). According to the invention, provision is made for an annular chamber between the central valve (12) and the rotor (8) to be divided by a sleeve (30) into two annular chambers (19, 20), wherein one of the two annular chambers (19) connects the first working connection (A) to the first rotor connection (11) and the other annular chamber (20) connects the second working connection (B) to the secon…
