摘要： An actuating system is provided that includes a differential hydraulic cylinder containing a piston and a piston rod connected to one side of the piston. A first or head chamber (53) is defined in the cylinder and is bounded by the one side of the piston, to which the piston rod is not connected. A second or rod chamber (54) is also defined in the cylinder and is bounded by the other side of the piston, to which the piston rod is connected. An actuatable assembly is provided that is adapted to be connected to either the hydraulic cylinder or the piston rod. Finally, a proportional control valve is provided which is adapted to actuate the hydraulic cylinder by controlling the amount of fluid supply to the first chamber, wherein the supply pressure is connected to the second chamber.

摘要： A hydraulic control valve has a solenoid with a coil having an interior. The solenoid also has a pole shoe inserted partially into the interior of the coil, wherein the interior of the coil defines an armature chamber and wherein the pole shoe delimits the armature chamber axially. The solenoid also has an armature arranged in the armature chamber and moveable in the armature chamber relative to the coil. The solenoid further has an armature plunger connected to the armature, wherein the pole shoe has a central bore and wherein the armature plunger is received in the central bore and penetrates the pole shoe. A hydraulic part with a valve housing formed as a mounting bushing and resting against the pole shoe is provided. The valve housing has an axial valve bore. The hydraulic part also has a low pressure area surrounding the valve housing, wherein the valve housing has at least one radial bore connecting the axial valve bore with the low pressure area. The hydraulic part has a valve slide slidably arranged in the valve bore and configured to be moved by the armature via the armature plunger. Between the pole shoe and the valve housing a fluid chamber is formed, wherein the fluid chamber has a fluid connection with the armature chamber and with the low pressure area. The fluid connection is located external to the at least one radial bore.

摘要： An actuating magnet is provided for a magnetic valve for a nonmagnetic pressure pipe, that is connected to at least one pole body, in which an armature is developed, and onto which at least two annular sleeves, having a ring lying between them, are slipped, in whose area a gap is situated that is developed between the armature and the pole body. Thereby, the actuating magnet may be developed in a simple manner by slipping annular sleeves and separating rings onto the pressure pipe.
