Abstract: A directly-controlled hydraulic directional valve includes a housing, control piston, first and second springs, double-stroke solenoid, spring plate, adjustment device, and electronics. The piston is longitudinally displaceable in a bore in the housing, either directly or via a control sleeve. The springs are positioned in a region of an end of the piston remote from the solenoid. One end of each spring is supported on the spring plate, which is clamped between the springs and the piston. The other end of the first spring is fixed to the housing, and the other end of the second spring is fixed to the adjustment device. The first spring exerts a force on the piston in a first direction, and the second spring exerts a force on the piston in a second opposite direction, so as to bias the piston into a preferred position.

Abstract: A valve has a valve housing which is connected to an electronics unit. The electronics unit has an electronics unit housing which has an aperture in order to establish electrical contacting with an actuator of the valve. A portion of the actuator may protrude into the aperture. Here, play is provided between the aperture and the portion of the actuator.

Abstract: A linear solenoid includes a pole tube; a housing jacket that encloses the pole tube; a coil that encompasses the pole tube; and a displaceable armature that is received in the pole tube. An overlap range between the housing jacket and an axially displaceable component that is in operative connection with the pole tube adjusts in order to adjust a magnetic force. The component is adapted to be actuated from outside in a mounted condition of the linear solenoid. The pole tube guides the component axially and the component has an external thread engaged with an internal thread of the housing jacket.

Abstract: With a magnet arrangement for an electromechanical drive with a cylindrical armature guided in a pole tube, the position of the armature is transformed into an electrical signal. Provided for this is a displacement sensor which is connected to the armature and has a fixed part and a movable part. One side of the armature is formed such that it transfers the movement of the armature, and the other side of the armature is connected to the movable part of the displacement sensor. The pole tube is provided with a closure part on the side of the displacement sensor. A pressure tube is led to the outside through an axial clearance of the closure part. The movable part of the displacement sensor moves in the pressure tube. The pressure tube is enclosed by the fixed part of the displacement sensor. In order to prevent the displacement sensor from being damaged by vibrations, the fixed part of the displacement sensor is arranged in a clearance of the closure part.

Abstract: What is disclosed is a method for manufacturing a valve piston, as well as a valve piston, wherein flow in the fine control range is determined through control windows formed by a through opening extending through the valve body.
