Abstract (en)
[origin: US2007095315A1] The invention relates to a control valve ( 20 ) for an apparatus ( 1 ) for the variable setting of the control times of gas exchange valves ( 110, 111 ) of an internal combustion engine ( 100 ), having a valve housing ( 22 ) of hollow configuration which has at least one inflow connection (P), at least one outflow connection (T) and at least two working connections (A, B), and having a control plunger ( 35 ). In order to retain relatively high flexibility in the design of the control valve components ( 22, 35 ) and to simplify the connection of the control valve ( 20 ) to the surrounding construction ( 3 ), it is proposed to arrange a pressure medium guide insert ( 27 ) of hollow configuration within the valve housing ( 22 ), and to form at least one pressure medium channel ( 34 ) which extends substantially in the axial direction, the pressure medium guide insert ( 27 ) engaging around the pressure medium channel ( 34 ) at least partially, the pressure medium channel ( 34 ) communicating with at least one of the connections (A, B, P, T) and, via a radial opening ( 33 b-d), with the interior of the pressure medium guide insert ( 27 ), and the control plunger ( 35 ) being arranged within the pressure medium guide insert ( 27 ).
