20090051215 | METHOD FOR OPERATING A BRAKE SYSTEM FOR MOTOR VEHICLES - The invention relates to a method for operating a braking system for motor vehicles with electrically actuated hydraulic valves, the coils of which are powered up, at least in phases, with currents which modify the currentless state of the hydraulic valves, in order to heat the hydraulic fluid present in the system. The hydraulic fluid is heated via a heating profile which, in accordance with the hydraulic fluid temperature, activates the heating phase of the hydraulic fluid. The heating profile consists of a first heating phase and, subsequent thereto, a second heating phase. During the first heating phase, the coils are powered up in such a way that the coil temperature at the end of the first heating phase corresponds to a pre-defined temperature value of the coil which is at least approximately maintained during the second heating phase when powering up the coils. | 02-26-2009 |
20100316520 | LIQUID PUMP - The invention relates to a liquid pump having a pump housing, a pump unit for generating a pilot pressure, a drive shaft used to drive the pump unit and guided out of the pump housing on a drive/output side, and a sealing unit sealing the passage. When the liquid pump is subjected to an admission pressure, the pressurized liquid generates, in the region of the sealing unit, at least one pressure field facing the sealing unit and at least one pressure field facing away from the sealing unit. According to the invention, an asymmetrical arrangement of the pressure fields is provided. | 12-16-2010 |
20120267555 | VALVE INSERT FOR A VALVE CARTRIDGE, CORRESPONDING VALVE CARTRIDGE FOR A SOLENOID VALVE, SOLENOID VALVE HAVING SAID VALVE CARTRIDGE AND METHOD FOR PRODUCING A VALVE INSERT - A valve insert for a valve cartridge of a solenoid valve, wherein the valve insert is produced as a one-piece, slotted sleeve from a sheet metal strip and has at least one radial bore as an inlet and/or drain opening of a fluid flow and to a corresponding valve cartridge or to a solenoid valve having such a valve insert and to a method for producing a valve insert. The at least one radial bore is designed having a trumpet-shaped geometry in order to specifically influence the flow characteristics of the fluid flow. | 10-25-2012 |
20120280158 | Magnetic Valve having a Core Sleeve and Method for Welding Thereof - A magnet valve has a core sleeve in which a valve element is longitudinally movably arranged and has at least one housing sleeve overlaying the core sleeve which is connected to the core sleeve by welding from the outside. The weld is designed via a circumferential section or a plurality of circumferential sections of the housing sleeve forming at least one weld-free zone. A method for welding such a core sleeve of a magnet valve to the housing sleeve is also disclosed. The weld is made via a circumferential section or a plurality of circumferential sections of the housing sleeve, leaving at least one weld-free zone. | 11-08-2012 |
20120315175 | Double Internal Gear Pump - A double internal gear pump has two internal gear pumps having a common pump shaft. A partition is formed between the two internal gear pumps, and the partition has a frustoconical circumferential surface which contacts an opposing surface in a sealing manner in a pump housing. Pump inlets and pump outlets can be led through the partition. The frustoconical circumferential surface of the partition is advantageous because it removes the necessity of pressing into the pump housing and canting the partition. In addition, a seal on the circumference of the partition is ensured with great reliability. | 12-13-2012 |
20140014869 | Valve for Controlling Fluids - The disclosure relates to a valve for controlling fluids, including a valve body defining a passage opening, a tapering valve seat formed on the valve body, a closing element configured to open up and to close off the passage opening at the tapering valve seat, and a protruding region adjoining the tapering valve seat. The protruding region extends over only part of a circumference of the tapering valve seat. | 01-16-2014 |
20140110614 | MAGNETIC VALVE - A magnetic valve includes a valve component and a valve body that engages around a region of the valve component in a hood-like manner and in a sealing manner in at least one sealing region. A flow chamber is formed between the valve body and an end face of the valve component. The valve component has an axially running through-channel with a constant cross-section which passes through the end face and which opens into the flow chamber so as to form an axial duct for a fluid. The valve body has a through-opening that is fluidically connected to the flow chamber and is configured to be closed by a closing element that is movably arranged on a valve body face that faces away from the flow chamber. The end face is configured as a type of lip seal ring. | 04-24-2014 |

20110227280 | DEVICE FOR FEEDING SHEETS TO A SHEET STACK - In a delivery of a sheet-processing machine, in particular a printing press, provision is made for chain gripper systems for holding the sheets to be transported at the leading and trailing edges thereof. The holding devices are configured such that they can be displaced relative to one another for the purpose of format adjustment. The chain gripper system has a sprocket drive shaft and a sprocket deflection shaft for the chains of the chain gripper system. Here, provision is made for both the sprocket drive shaft and the sprocket deflection shaft to have a clutch. | 09-22-2011 |
20140013977 | POWDERING DEVICE FOR A PRINTING PRESS AND METHOD FOR OPERATING THE POWDERING DEVICE - A powdering device for a printing press includes a metering roller and a manifold. A plurality of injectors are provided downstream of the manifold in a conveying direction of the powder. The powdering device is operable in accordance with a method in which a total powder stream is subdivided into partial powder streams that are subsequently separately mixed with compressed air to create powder/air streams. | 01-16-2014 |
20140102249 | GUARD FOR A MACHINE FOR PROCESSING SHEETS, E.G. PUNCH OR PRINTING MACHINE, IN PARTICULAR IN THE REGION OF THE EXTENSION ARM - On a machine for processing sheets it is provided, in particular in a region of an extension arm, to completely close a rear opening on the end side by at least one upper and one lower cover. Lateral openings are also closable by movable guards, which at least partially are formed from a transparent material. | 04-17-2014 |
20150076762 | APPARATUS FOR REMOVING SHEETS - An apparatus for removing sheets from a transport path of a sheet-processing machine for depositing the sheets onto an auxiliary stack, includes a delivery drum for removing the sheets from the transport path upstream of a main stack, as viewed in the transport direction, and depositing the sheets onto an auxiliary stack in a manner which is retarded by using a suction belt transport system and a suction belt brake system which is associated with the latter. The suction belt transport system and the suction belt brake system are disposed above the auxiliary stack. | 03-19-2015 |
