Title:
CAMSHAFT-ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/144143
Kind Code:
A3
Abstract:
The invention relates to a camshaft-adjusting device, comprising a vane cell adjuster having a stator (1) that can be connected to a crankshaft of an internal combustion engine and a rotor (2), which is rotatably supported in the stator (1) and which can be connected to a camshaft, wherein a plurality of webs are provided on the stator (1), which webs divide an annular space between the stator (1) and the rotor (2) into a plurality of pressure chambers (3, 4, 5), wherein the rotor (2) has a rotor hub (6) and a plurality of vanes (7, 8, 9) extending radially outward from the rotor hub (6), which vanes divide the pressure chambers (3, 4, 5) into two groups of working chambers (10, 11, 12, 13, 14, 15) having a different acting direction, into each of which working chambers pressure medium flowing in or out in a pressure-medium circuit can be admitted, and a locking device (16) for locking the rotor (2) in at least one locking position in relation to the stator (1), wherein the locking device (16) can be brought into an unlocking position by pressurization of a first pressure-medium line (17), wherein the pressure medium in the first pressure-medium line (17) can flow out into a pressure-medium reservoir (T) via a first outflow pressure-medium line (18) during the transition from the unlocking position to a locking position, wherein the first pressure-medium line (17) of the locking device (16) is connected with regard to flow to the pressure-medium reservoir (T) via an additional outflow pressure-medium line (19) during the transition from the unlocking position to the locking position.
