Oscillating motor adjuster

摘要

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 second rotor connection (13).

1. An oscillating motor adjuster with
a stator, a rotor which is positioned within the stator and is displaceable relative to the stator on a first rotor connection by hydraulic pressure in a first direction, and relative to the stator on a second rotor connection by hydraulic pressure in a second direction, a central valve which projects through a hub of the rotor and is inserted into a camshaft, wherein the central valve has a first working connection and, at an axial distance from the first working connection, a second working connection, wherein the first working connection is connected to the first rotor connection and the second working connection to the second rotor connection, wherein disposed between the central valve and the rotor is an annular chamber, wherein a sleeve is disposed in the annular chamber and divides the annular chamber into a first annular chamber and a second annular chamber, wherein the first annular chamber provides a passageway from the first working connection to the first rotor connection, and the second annular chamber provides a passageway from the second working connection to the second rotor connection; wherein a portion of a radially exterior surface of the sleeve defines the first annular chamber between the rotor and the sleeve, and a portion of a radially interior surface of the sleeve defines the second annular chamber between the central valve and the sleeve.
