Abstract: Techniques for setting up network components in a wind power plant communication network. The communication network comprises a plurality of network components each comprising a component type identifier and being suitable for serving a function which can be changed by a configuration command, and a perimeter component configured for communication with the plurality of network components and configured for communication with an external server outside the wind power plant communication network. The external server has access to a list of component types and at least one corresponding configuration for each network component.

Abstract: A mechanical system has a component, which is movable under friction. An oscillating micromotion (dither) is impressed upon the component, which, if necessary, is added to a non-oscillating base motion of the component. It is provided that the micromotion (without the base motion that is additional, if necessary) is faster within a period of the oscillation in the one direction and is of shorter duration than in the opposite direction (asymmetrical dither).

Abstract: In a method for operating a fluid valve for controlling or regulating a fluid, having at least one movable valve component is displaceable with the aid of at least one electrical actuating signal which contains at least one first actuating signal portion which causes an oscillating valve motion of the valve component. Pressure oscillations generated in the fluid due to the oscillating valve motion are detected, and are used for regulation of the oscillating valve motion caused by the first actuating signal portion.

Abstract: A hydraulic unit has a closing plate having at least one recess in which a supply passage and a discharge passage for pressure medium open, an electromagnetic regulator inserted in said recess and having a magnetic part composed of a housing, a magnetic coil with a coil core, a flux conducting element and an armature. The closing plate has a supply projection extending in the recess of the closing plate and receiving the supply passage. The supply projection has an end extending in the magnetic part of the regulator and ending in a sealing seat. The sealing seat cooperates with the armature of the magnetic part for controling the discharge passage.

Abstract: A hydraulic unit is connected with a control plate of a transmission with the use of a sealing element. The sealing element performs in addition to its sealing function for sealing the hydraulic passages from one another and from outside, also a parallel filtering function for preventing the dirt contained in the pressure medium from regulators of the hydraulic unit. Addition to the reduction of components, the sealing element can be mounted automatically and reliably fixed in position. Also, the sealing element can be produced cost-favorably and in any complex shape. Adaptation of the sealing element to the corresponding sealing applications is possible without additional expenses.

Abstract: An electromagnetically operated pressure switching valve has a valve housing, a magnet coil arranged inside the valve housing, a magnet core associated with the magnet coil and having a passage for a pressure medium provided with a valve seat, a magnet armature, a valve closing element arranged in the valve housing for controlling a flow of the pressure medium. The magnet armature has a portion extending in the magnet coil to an area of a greater magnetic flux density. The portion of the magnet armature cooperates with the valve seat of the passage and is limited by a ring-shaped circular flange-like edge extending outside of the magnet coil.

Abstract: A coil former with injection-molded encapsulation has a top fitting in which coil wire guides for guiding a coil wire are formed. By virtue of the specific shape and arrangement of the coil wire guides, it is ensured, in particular together with a special design of the housing which surrounds the coil former, that the coil wire is only stressed in its longitudinal direction. As a result, damage or preliminary damage of the coil wire is prevented and reliability is increased.

Abstract: An electromagnetic valve, in particular a switching valve for automatic transmissions for motor vehicles has a magnet housing, a synthetic plastic body in which the magnet housing is always partially embedded, a magnet coil and a magnet core received in the magnet housing, a magnet armature, a valve member with which the magnet core cooperates through the magnet armature, and a valve closing part provided with pressure medium passages and having a connecting flange, the synthetic plastic body having an edge which surrounds the magnet housing and extends outwardly beyond it, the circumferential edge of the synthetic plastic body surrounding the connecting flange of the valve closing part, the synthetic plastic body and the connecting flange being connected in the region of their adjoining circumferential surfaces.

Abstract: An electromagnet valve has a housing having an end side, a magnet coil and a magnet armature received in the housing, a valve member, and a valve closing part provided at the end side of the housing and connected with the latter by a flange connection. The valve closing part has a valve seat which cooperates with the valve member, a pressure chamber surrounding the valve seat, and at least one pressure medium passage connected with the valve seat. The valve closing part is composed of injection molded synthetic plastic and has at an end side facing the housing a ring-shaped recess which surrounds the pressure chamber at a distance from the latter.
