摘要： A method for operating a hydraulic system having at least one supply device, in particular a hydraulic pump (39)), which supplies different hydraulic consumers is characterized in that a synchronizing device (33, 35) ensures that, if at least one hydraulic consumer is not supplied sufficiently, the deficit in volumetric flow for said consumer is compensated for in such a way that all the consumers compensate for the deficit equally.

摘要： The invention relates to an actuating device for the activation of a hydraulic load (10), such as a working cylinder, by means of a fluid supply flow. As a result of the fluid supply flow for the load (10) being activated by means of an activating unit (48) in such a way as to obtain a damped actuation with a soft starting behaviour, soft accelerations fundamentally occur for a hydraulic load, which soft accelerations are perceived by an operator to be comfortable with regard to the continuous speed behaviour.

摘要： The invention relates to a fluid cooling device comprising a combined (10) cooling, filtering, pumping and control device, whereby fluid pumped by a pump (16) in a fluid circuit (18) can be filtered by a filtering device (14) and can be cooled by a cooling device (12). In said invention, a control device (42) has a fluid flow distributor (44). Said fluid flow distributor (44) is located in the secondary arm (46) of the cooling device (12) and said device can be controlled independently of the temperature of the fluid to be cooled in such a way that at lower fluid temperatures below a predefinable temperature threshold value (54), the cooling device is at least (12) partially supplied with fluid, thereby improving upon known fluid cooling devices and thereby subjecting the cooling device to a lower load during operation.
