Abstract (en)
[origin: WO2011051377A1] The invention relates to a camshaft adjustment assembly (1), wherein a control valve (4) is provided for controlling the flow of the pressure fluid in the hydraulic chamber, wherein the control valve (4) is supplied with pressure fluid from the region of a camshaft bearing (5) by means of a fluid channel (6, 7, 8, 9). In order to enable an improved fluid line at low component weakening, according to the invention the fluid channel (6, 7, 8, 9) comprises an annular chamber (6), which is formed between the axial end (10) of the camshaft (2) at least sections of which have a tubular design, a flange-like section (11) of a housing element (12) that is non-rotationally connected to the camshaft (2) and in which the control valve (4) is mounted, a radially inner delimiting surface (13) of the housing element (12), and a section (14) of the wall of the camshaft bearing (5).
