    Abstract: An arrangement for the electrohydraulic remote control of directional valve in which a variable displacement pump provides fluid under pressure to a load or a hydraulically operated device. Signal transducers are arranged at the pump and the load to provide electrical signals as a function of the pressures prevailing at the pump and the load. An electrical control unit compares the signals from the transducers, and is operatively connected to an electrohydraulic actuated positioning means in the pump when the signals correspond. The regulation is such that the fluid flow from the pump is controlled as a function of the load magnitude.

    Abstract: A spring-biased regulating valve has a first regulating position directing fluid from a pump at a constant pressure to a first outlet, and directing excess fluid to a second outlet. The regulating valve is held in the first regulating position by fluid pressure in a regulating chamber to which fluid is supplied through a throttle from the first outlet. When the pressure in the first outlet rises above a desired constant value, a biased control valve responds to the pressure increase and relieves the pressure in the regulating chamber so that the regulating valve moves to a second regulating position in which all the fluid from the pump is supplied to the second outlet until the pressure in the first outlet has again its desired constant value. The consumer connected to the second outlet is not disturbed by interruption of the load on the first outlet, and different pressures are possible for the first and second outlets.

    Abstract: An arrangement for controlling remotely hydraulic valves located between a variable displacement pump and a load supplied from the pump. The valve has a control slider the position of which is indicated through a signal generator on the slider. Control levers are also coupled to the slider and the position of these levers is indicated through another signal generator coupled to the levers. A control unit connected to the signal generators, compares their signal outputs and actuates electrohydraulic positioning means for controlling the pump flow as a function of the deflection of the control levers.

    Abstract: A spring-biased regulating valve directs fluid from a pump at a constant pressure to a first outlet up to a certain amount required by a consumer apparatus, and directs at the same time excess fluid to a second outlet. When the pressure in the first outlet rises above the desired constant value, a biased control valve responds to the pressure increase and causes the regulating valve to direct all the fluid from the pump to the second outlet until the pressure in the first outlet has again its desired constant value.

    Abstract: An arrangement for controlling directional valves electrohydraulically. The valve is connected between a constant pump and a load which is actuated through fluid under pressure from the pump. The directional valve has a control slide to which a signal transducer is secured to give a signal indicative of the position of the control slide. Control levers are also arranged with the control slide and have signal transducers for indicating the deflection of the control lever from a neutral position. A control circuit is connected to the signal transducers for comparing their signal outputs, and to actuate electrohydraulic positioning member on the control slide for controlling the position of the control slide dependent upon the position of the control lever. A switching valve controls the neutral fluid flow from the pump to the load as a function of the position of the control lever.

    Abstract: An electrohydraulic control valve has a slider spool valve body to connect, or disconnect a double-acting hydraulic power device from a source, or a drain, respectively; a spring maintains the spool valve in centered position. The spool valve is further provided with a double-acting control piston having faces of unequal size, slidable in a chamber, and electromagnetic on-off valves interconnect the piston chambers formed by the two sides of the double faced piston, with the and drain of the hydraulic pressure fluid respectively, to shift the position of the control piston and hence of slider.
