| 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 |

| 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 |

| 20080265190 | Electromagnetic Pressure Regulating Valve Device Having an Integrated Pressure Sensor - An electromagnetic pressure regulating valve device for regulating a hydraulic pressure including at least one pressure regulating valve which includes a solenoid part having at least one bobbin holding an electric coil, a coil core and a movably guided armature; a valve part having at least one supply connection, one return connection, one load connection and one actuating element operated by the armature and cooperating with a valve seat; and an electronic part having at least one pressure sensor for measuring the hydraulic pressure present at the load connection. At least the pressure sensor is situated on an end of the solenoid part facing the valve part upstream from the electronic part. Positioning the pressure sensor close to the valve part may substantially reduce the filter effect of the transmission link, and the hydraulic pressure to be measured is therefore transmittable free of errors up to a much higher cutoff frequency. This may result in a higher measurement accuracy, and therefore also a higher regulation accuracy, of the pressure regulating valve. | 10-30-2008 |
| 20110094590 | Method For Operating a Fluid Valve Via An Oscillating Valve Motion - 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. | 04-28-2011 |
