摘要： A hydraulic control device according to the invention is of load-sensing design and serves to actuate a first hydraulic load and a second hydraulic load. Also provided are a first control valve for actuating the first hydraulic load and a second control valve for actuating the second hydraulic load. A first load signal can be measured on the basis of a load pressure with which the first hydraulic load is acted on, and a second load signal can be measured on the basis of a load pressure with which the second hydraulic load is acted on. Pressure medium from a pressure medium source can be supplied in parallel to the first control valve and to the second control valve. A load signal path can, in order to actuate an adjusting element which is assigned to the pressure medium source, be acted on with a highest presently measured load signal. A limiting device allows the second load signal to be limited to a predefined signal limit value. A switching means can be actuated by means of the second load signal such that, at the latest when the second load signal reaches the signal limit value, the signal conveyed on the load signal path is limited by the limiting device.

摘要： A hydraulic system for utility vehicles is disclosed for prioritized pressure medium supply to internal and external pressure medium consumers (6, 11, 12), which are fed via load sensing spool valves (20, 26), the external pressure medium consumers (11, 12) being supplied with pressure medium via a priority valve (17). In order to improve the work quality of an implement driven by an external pressure medium consumer, the present invention provides that priority can be selectively assigned to the internal (6) or the external (11, 12) pressure medium consumers. It is thus possible for the driver, in order to ensure optimum operation of the utility vehicle in critical situations, to give priority to external pressure medium consumers. In this way during operation of an implement for dispersion of substances, better work quality can be attained, as a reduced supply and thus slower function of the internal power lift are accepted.

摘要： The invention relates to a valve arrangement having an adjustable control valve (10), comprising a control slide (12) for actuating at least one consumer connection (A,B), and having an LS control line, wherein the differential pressure of two actuating pressures (Xa, Xb) serves for the actuation of the control slide (12). Due to the fact that the actuating pressures (Xa, Xb) also actuate a logic valve, which in turn influences an additional valve, and/or actuates a pressure scale that is connected upstream to the control valve (10) having the control slide (12), the difference of the two actuating pressures (Xa, Xb) initially displaces the control slide of the control valve, wherein the higher or the lower of the two actuating pressures (Xa, Xb) either actuate the further valve in the form of the additional valve, and/or influences the pressure scale.

摘要： The force feedback poppet valve includes a valve body having a main chamber, a first port, and a second port. The force feedback poppet valve further includes a main poppet disposed within the main chamber and movable between an open position and a closed position to control fluid flow between the first port and the second port. The main poppet forms a control chamber within the main chamber. The force feedback poppet valve further includes a first passage communicating the control chamber with the second port, a second passage communicating the control chamber with the first port, and a pilot valve having a pilot poppet for controlling fluid flow between the control chamber and the first port through the second passage. The force feedback poppet valve further includes a pressure compensator disposed within the main poppet, and fluidly connected to the second port via the first passage. The force feedback poppet valve further includes a first spring coupled between the main poppet and the pilot poppet to provide a force proportional to a distance between the main poppet and the pilot poppet, and a second spring coupled between the pressure compensator and the pilot poppet to provide a force proportional to a distance between the pressure compensator and the pilot poppet.

摘要： A hydraulic circuit controls flow of fluid between first and second ports of a hydraulic actuator, such as a cylinder/piston arrangement and each of a supply conduit and a tank return conduit. The hydraulic circuit operates in standard powered operating modes as well as powered and unpowered regeneration modes. In a powered operating mode, a conventional pressure compensated spool valve determines the velocity of the hydraulic actuator. A workport blocking valve connects one workport of the spool valve to the first port and the other workport is connected to the second port. A regeneration shunt valve is directly connected between the first and second ports of the hydraulic actuator. In a regeneration operating mode or a mix of powered and regeneration modes, a combination of the spool valve, the workport blocking valve, and the regeneration shunt valve determines the velocity of the hydraulic actuator.

摘要： An arrangement for controlling two drive units which interact with one another, one of which includes a hydraulically driven motor (2). The motor drives a varying load, and one or more valves (6, 7) control hydraulic fluid flow through the motor during operation and for starting and stopping of the motor. One of the valves is a flow control valve (7) for flow control of the hydraulic fluid flow through the motor. The second drive unit (37) performs a working movement which, under the action of hydraulic flow influences the loading of the motor. The flow of the hydraulic fluid to the second drive unit is controlled in a coordinated way with the control of the flow through the motor.
