    摘要： An LUDV-circuit for controlling at least one of a lower-load consumer and a higher-load consumer is disclosed, wherein a metering orifice and a downstream pressure compensator for maintaining constant the pressure drop across the metering orifice constant are associated with each consumer. The pressure compensator of the lower-load consumer is associated with a bypass channel capable of being controlled open, whereby the pressure compensator of this consumer may be bypassed.

    摘要： The present invention proceeds from a control arrangement for at least two hydraulic consumers which has a positive displacement pump the setting of which is variable by a load-sensing regulator which can be acted on via a load-signaling line by the highest load pressure, on which a maximum-pressure and an output regulation are superimposed, two displaceable metering diaphragms a first one of which is connected between the positive displacement pump and a first hydraulic consumer and the second between the positive displacement pump and a second hydraulic consumer, and two pressure compensators a first one of which is arranged behind the first metering diaphragm and the second behind the second metering diaphragm and the regulating pistons of which can be acted on, in opening direction on a front side, by the pressure behind the corresponding metering diaphragm and in closing direction on the rear side by the pressure in the load-signaling line. In order that the pump pressure does not become maximum, since, upon simultaneous actuation of the two hydraulic consumers, the one consumer is moved against a stop or carries out a clamping function, it is provided that, in the event of such joint control of only the first and the second hydraulic consumers, the load-sensing regulator as from a limiting pressure which lies below the maximum pressure can be acted on by a pressure which is dependent only on the load pressure of the one first hydraulic consumer.

    摘要： A control arrangement to supply-pressure medium to at least two hydraulic consumers having a variable-displacement pump controlled according to required flow and the setting of which can be changed by a, pump controller as a function of highest load pressure of the actuated hydraulic consumers; two adjustable meter-in variable restrictors, a first of which is arranged between a feed line, which leads from the variable-displacement pump, and a first hydraulic consumer, and the second of which is arranged between the feed line and a second hydraulic consumer; and two pressure compensators, a first of which is connected downstream of the first meter-in variable restrictor and the second of which is connected downstream of the second meter-in variable restrictor, and the control piston of which can be acted on in opening direction by the pressure downstream of the associated meter-in variable restrictor. To ensure in this type control arrangement that a brief excess quantity from the variable-displacement pump is not passed on to the hydraulic consumers, the control pistons of the pressure compensators can be acted on in closing direction by a control pressure which is present in a rear control space, is derived from the feed pressure prevailing in the feed line with aid of a valve device and changes with the feed pressure. There is also a pressure differential valve which, with small structure, allows a pressure at its outlet to follow, with a fixed pressure difference, a rising pressure at its inlet. Together with a restricted pressure relief of the outlet to the tank, this type pressure differential valve ensures in each case a fixed pressure difference between the outlet pressure and the inlet pressure. This valve is particularly suitable for use in the control arrangement.

    摘要： The invention concerns a hydraulic control circuit in which the pressure medium conveyed by a hydraulic pump of variable delivery (10) is fed, in each case via a metering aperture (17, 31), as a priority to a first hydraulic consumer (14) and only secondly to a second hydraulic consumer (15). A priority control system is now produced without additional delivery losses and with sufficient amounts of pressure medium being conveyed in that the valve member (48) of the priority valve (45) can be acted upon in the closure direction of the connection between the first connection (46) and the second connection (47) by a pressure prevailing in a line section (13) upstream of the first metering aperture (17).
