    摘要： A control valve for a device for changing the control times of an internal combustion engine, having a substantially hollow-cylindrical valve housing, a control piston which is arranged within the valve housing and can be displaced axially, a pressure medium connection, two operating connections, and at least one tank connection. The operating connections, the pressure medium connection and the tank connection are formed as radial connections. It is possible for the operating connections to be connected to the pressure medium connection and the tank connection by axial displacement of the control piston within the valve housing. The operating connections are arranged adjacently.

    摘要： A control valve for a hydraulic adjuster for the camshaft of an internal combustion engine is provided, wherein an actuator acts on a pressure part (12) embedded in a control piston (5). In order to prevent the piston (5) from being blocked in the valve housing by the expansion thereof caused by the pressure part embedment, the pressure part (12) and/or the control piston (5) is/are provided with radial recesses (34) in the embedment area (13) which make it possible to limit joining forces and the resulting radial expansion of the piston (5). Alternatively or in addition, the external surface of the control valve (5) has a reduced cross-section in the embedment area (13).

    摘要： The invention relates to a control valve for influencing the action of a pressure medium on a camshaft adjuster of an internal combustion engine. A control valve of said type comprises a valve housing (72), in which a displaceable control piston (71) is arranged in a blind bore. According to the invention, the valve housing (72) is produced with a through bore (73) instead of a blind bore, into which through bore (73) a housing insert (79) is clipped into a groove (80). The housing insert can serve to support a pressure spring (76), and can also additionally have recesses, in the region of which the housing insert (79) serves to form a port, for example to a tank T.

    摘要： An electromagnetic actuating unit (10) of a hydraulic directional control valve (9) is provided having an armature (18) which is arranged such that it can be axially displaced within an armature space (30), and includes a pole core (29) which is arranged in a receptacle (27a) and delimits the armature space (30) in a movement direction of the armature (18). Constructions are provided in order to avoid deposits on a guide surface of the armature (18), as a result of which the dynamics and the response behavior of the actuating unit (10) are increased and hysteresis effects and the risk of a malfunction of the actuating unit are minimized.
