Abstract: A method and an apparatus for skinning and trimming a product to be treated, in which the product to be treated is delivered on a delivery device to a cutting unit. The cutting unit is embodied as a cutting blade and is associated with a traction roller. A linear rotary device is received by a retaining device and is disposed adjacent the cutting unit. In an operating position, the rotary device engages the product to be treated and sets it into rotation, to enable skinning in the circumferential direction of the product to be treated. After the skinning operation, either the rotary device is transferred to a discharge position and the product to be treated is removed from the apparatus via a discharge device or the delivery device is retracted so that the product being treated can drop downward. Another option for discharge of the product for treatment after the skinning operation is for the product being treated to be removed from the processing position laterally by an arm.

Abstract: A vehicle hydraulic brake system having an anti-lock protection device and an automatic braking system, particularly when driving around bends. During automatic braking, an auxiliary pressure source supplies a pressure instead of the main brake cylinder and this pressure can be individually set by pressure reduction in the wheel brakes by means of the anti-lock protection device. For this purpose, cylinders with separating pistons are located between the auxiliary pressure source and the anti-lock protection device. The auxiliary pressure source supplies substantially lower auxiliary pressures than known systems by supplying pressure to the inlets of feed-back pumps by arranging valves which permit temporary pressure increases to the extent necessary for automatic braking by means of these feed-back pumps. The system requires less energy and less noise is caused in automatic braking operations.

Abstract: A fuel injection nozzle for internal combustion engines that has a nozzle body with a valve seat disposed on the combustion chamber end and an outwardly-opening valve needle with a closing head, which has a closing cone that works together with the closing valve seat. At least one injection port is disposed in the closing head at an angle with respect to the axis of reciprocation of the valve needle, and is opened by a control edge on the nozzle body depending on the inlet pressure of the fuel. In order to minimize any deflection of the injection stream flowing out of the injection port relative to the alignment of the injection port, the port is divided into at least two parallel conduits, which are separated from each other by a dividing wall and which upon the opening stroke of the valve needle are unblocked one after the other by the control edge.

Abstract: A fuel injection device for internal combustion engines having a high pressure accumulation chamber, which can be filled by a high pressure fuel pump, from which chamber high pressure lines lead to the individual injection valves. Control valves for controlling the high pressure injection at the injection valves are formed in the individual high pressure lines. Additional pressure storage chambers are inserted in the individual high pressure lines as well, between these control valves and the high pressure accumulation chamber. In order to prevent the high system pressure from continually contacting the injection valves, the control valve is embodied so that during the injection pauses, it closes the communication between the injection valve and the pressure storage chamber and opens a communication between the injection valve and a relief chamber.

Abstract: A device for moving large and heavy apparatuses combining modular rail sections positioned one after the other to form two parallel rails onto which slides a load-carrying plate extending transversely between the rails. The upper surface of the rail section has a central row of upwardly projecting supporting elements positioned at regular intervals along its length. The undersurface of the carrying plate has two opposite edge portions each having two parallel rows of guiding elements projecting down and positioned at regular intervals along its length. When the plate is positioned on top of the rails, the two rows of guiding elements define a guiding channel which may releasably engage the central row of supporting elements projecting up from the corresponding rail. The upper layer of each supporting element and the bottom layer of each guiding element are made of a friction material, either low friction material to facilitate movement therealong or high friction material to enhance friction.

Abstract: A solenoid valve with pressure limitation for motor vehicle brake systems with slip control. The solenoid valve has a seat valve with the valve seat, valve element and restoring spring, which holds the seat valve in an open position. The valve element is fastened on a valve tappet, which is axially displaceable in a valve housing and is transferred into a seat-valve-closed position by an electromagnet when the electromagnet is supplied with current. In the valve-closed position, there acts a pressure-limiting spring, which fixes the valve-opening pressure of the seat valve. To achieve a structurally simple valve design with the advantage of simple and accurate setting and adjustment and also of simplified forward assembly of the solenoid valve, the valve tappet is subdivided into first and second tappet elements which are coaxial to each other and relatively displaceable, of which the first tappet element bears the valve element and the second tappet element can be driven by the electromagnet.
