Abstract (en)
[origin: EP2322769A1] The insert (9) has a pressure accumulator (20) loaded by spring force, where the insert is fixedly connected with a rotor (6) of a rotary motor adjuster (1). The pressure accumulator is arranged in a camshaft (5). A hydraulic part (2) of a valve (3) is radially arranged within the rotor and aligned to the pressure accumulator. The pressure accumulator is separated from the hydraulic part by a separation wall (30), where an end of a helical compression spring (31) is indirectly supported at the wall. Another end of the spring is supported at a valve piston (33).
