摘要:
For a power assisted steering system for vehicles, in particular passenger cars, there is provided a hydraulic circuit with a servopump, a three-way flow regulator valve which is located at the junction between the pump and a servoactuator and has a measuring throttle, located in the inflow to the servoactuator, as a fixed throttle and an outflow throttle which is located in a bypass of the latter and which determines a variable throttle cross section by means of a piston which is charged alternately as a pressure compensator. The piston, which is charged via an active actuator element, changes the outflow throttle cross section as a function of the current applied in order to change the volume flow which passes via the measuring throttle.

A mounting plate for electronic components, including cooling conduits that are integrated into a plate body and that are traversed by a coolant, a fixing device for mounting electronic components that are to be cooled being located on the plate body. The mounting plate has the fixing device including at least one first groove with an approximately C-shaped cross-section, which extends in a linear manner in the extension direction of the mounting plate. At least one screw nut is inserted and locked against torsion in the groove in order to form a screw connection with an electronic component.

A switching cabinet arrangement equipped with a main door and at least one auxiliary door having a locking device mounted on them, which has an actuating mechanism that causes an actuating device to unlock the auxiliary door as the main door is opened. The locking device has a blocking mechanism that acts on the actuating device and prevents the main door from closing when an auxiliary door is open.

A cable conduit for a switchgear cabinet, having a rack assembled from rack legs, at least a part of which have several profiled sides on an inside facing an interior, which extend at an angle with respect to each other and to a diagonal line of the rack and have a row of fastening receivers, wherein the cable conduit has a U-shaped profiled receiving section with a base leg and two lateral legs and can be closed by a cover section, which can be locked on the lateral legs. A dependable attachment of the cable conduit with an optimal cable reception space is achieved because the base leg of the profiled receiving section is matched to at least a portion of the contour defined by the profiled sides of the inside of a frame leg, or the profiled sides of the insides of two frame legs which are connected with each other, and can be connected with the profiled sides.

A control cabinet with a cabinet body, whose open front side can be successively closed by an inner door and a closing door presenting a closing device. The inner door can be fixed against the cabinet body at the top and at the bottom by means of a two-armed locking lever and the closing door can be fixed against the cabinet body by means of a locking bar. The closing door partly overlaps the inner door in the closing area. With mirror-symmetrical locking levers, no elements of the locking levers protrude over the free edge of the inner door in any position of the locking levers and the locking levers are easily operated.

A cable entry for a switch cabinet having an opening positioned in a floor of the switch cabinet and surrounded by a connecting layer. The opening can be closed off with bottom plates which can be placed one next to each other and connected to the connecting layer. The sides of adjoining bottom plates assigned to each other have angled edges fitted with sealing strips. The cables are fed into the switch cabinet between the sealing strips and sealed by deformation of the sealing strips. This invention provides for the edges of the bottom plates to be configured as a double fold, a first section of which points towards the upper or lower side of the bottom plate while the second end section of the double fold extends across the first section and protrudes from the lower or upper side of the bottom plate. The sealing strips extend across the width of the end section of the double fold. This results in a sufficiently broad sealing area using a simple bottom plate which only insignificantly limits the installation space available above and below the bottom plate.

A connecting element having a bracket for fastening side walls of a switchgear cabinet onto a frame profile of a switchgear cabinet frame and having a contact spring connected to the bracket for providing an electrical connection between the side walls and the frame legs of the switchgear cabinet frame. The contact springs have contact points disposed in the direction of the side wall, which contact points protrude above the contact surface of the frame profile on which a corresponding side wall is disposed.
摘要:
A switching cabinet with a rack having a base made of length and depth struts with connected vertical frame pieces. The vertical frame pieces are inserted into a cavity formed by the ends of the length and depth struts and are welded with the base to form a corner connector. It is possible to create a switching cabinet with a simple corner connector mounted on the rack. It is also possible to achieve precise alignment of the vertical frame pieces by providing them with centering pieces which are aligned with stops of the length and depth struts.
