| 20110146815 | FLUID VALVE ARRANGEMENT - The invention relates to a pressure controlling valve comprising a slidable spool ( | 06-23-2011 |
| 20110017310 | FLUID VALVE ARRANGEMENT - The invention relates to a method for controlling a fluid valve arrangement that includes a fluid conduit arrangement having a first conduit and a second conduit, the first and the second conduits being connectable with a fluid consumer; a supply connection arrangement having a pressure connection and a tank connection, and a number of valve arrangement for connecting the consumer to the pressure connection or the tank and a control device, which controls the valve arrangements. The method involves detecting output signals from opening degree sensors connected across at least the first and second valve arrangements to determine the magnitude and direction of a pressure drop across at least the first and second valve arrangements, and using the output signals to determine an operating mode for each valve arrangement. | 01-27-2011 |
| 20090266067 | ARRANGEMENT FOR OPERATING A HYDRAULIC DEVICE - A fluid system includes a controllable first pump unit for supplying fluid pressure to at least one implement; a prime mover arranged to supply a driving torque to the first pump The first pump unit is arranged to supply fluid pressure to the implement. The fluid system further includes a controllable second pump unit connected to a fluid accumulator. The prime mover is arranged to supply a driving torque to the second pump unit in order to accumulate fluid pressure in the accumulator during periods of low demand. Fluid pressure from the accumulator is arranged to drive the second pump unit to assist the prime mover during periods of high demand in order to supply an additional driving torque in excess of the available driving torque from the prime mover. | 10-29-2009 |
| 20090261819 | SENSOR ARRANGEMENT - A sensor arrangement is arranged to detect at least one position of a displaceable component in a fluid device, which fluid device comprises a wall enclosing a cavity, in which cavity the component is displaced by pressurized fluid selectively applied to the component. The sensor arrangement includes a magnetic sensor mounted outside the wall and a first sensor element that is connected to the magnetic sensor and extends through the wall and a predetermined distance into the cavity. The magnetic sensor is arranged to detect the position of at least one predetermined second sensor element located on the displaceable component by sensing a change in magnetic flux induced in the first sensor element by the second sensor element. | 10-22-2009 |
| 20080308327 | Power Generation Arrangement - The invention relates to a power generating unit mounted to a source of rotational energy and arranged to supply hydraulic pressure and flow to at least one driven accessory. The power generating unit comprises a housing removably mounted on the source of rotational energy, an input shaft adapted to be connected to the source of rotational energy, said input shaft comprising a first end provided with means for engaging the input shaft to a power output interface on the source of rotational energy, a second end connected to a hydraulic pump and means for selectively engaging the input shaft to the hydraulic pump. The input shaft, the means for selectively engaging the input shaft, and the hydraulic pump are arranged as an integral power generating unit within said housing. The invention further relates to a vehicle provided with such a power generating unit. | 12-18-2008 |
