摘要： A control for a hydraulic drive or actuator is provided, wherein the actuator has pressurized operating fluid applied thereto, and wherein the operating fluid is directed through an electrically controlled valve for establishing the amount of operating fluid to be fed to the actuator. An electrical signal for controlling the valve is provided by a computing device. In the computing device, a predetermined desired value for the position (or travel), force, or pressure of the actuator or drive is continuously calculated based, at any given time, at least on one measured or simulated state variable indicative of a condition of the drive or actuator at the time of calculation. The calculated desired value determines the amplitude of the electrical signal directed to an electrical actuating device of the valve. The computing speed of the computing device for determining the respective desired value is faster than the actuating velocity or speed of the valve.

摘要： A hydraulic valve includes a spool movable within a body to regulate flow across the valve. Movement of the spool is controlled by an electromagnetic actuator that operates either directly or through a pilot stage upon the spool. When operating through a pilot stage, the actuator varies pilot pressure by an operating member co-operating with an orifice. A flapper valve may be used to vary a pair of pilot flows in complementary manner. Feedback signals of pressure and spool position are provided to a controller which selectively combines the signals to monitor the operating parameters of the valve. The controller may modify the position signal with the pressure signal to obtain an indication of flow rate through the valve.

摘要： A hydraulic drive system for a construction machine includes a pump for delivering fluid under pressure from a fluid reservoir, at least one hydraulic actuator selectively driven by the pressurized fluid, and at least one closed-center directional control valve connected in parallel to the pump. The control valve has an "off" position which blocks fluid flow therethrough and at least one "on" position for controlling the flow of fluid to the hydraulic actuator. A control device generates a signal for actuation of the hydraulic actuator. A control unit receives the control device signal for operating the control valve associated with the hydraulic actuator. A bypass line leads from the pump back to the reservoir. A variable position bypass valve is interposed in the bypass line and controls flow through the bypass line. The control unit modulates the bypass valve for optimum operation. A hybrid control senses pressure in the actuator and modifies the control signal in response to the load pressure.

摘要： In many hydrostatic systems, the variable displacement pump is controlled by an operator moving a directional control valve to provide pressurized fluid to the displacement changing mechanism thereof which in turn varies the displacement responsive to the degree of pressurized fluid being directed to the displacement changing mechanism. In order to insure that the displacement of the Variable displacement pump is at the desired displacement, various forms of follow-up mechanisms have been required. These follow-up mechanisms are many times complicated and expensive to add to the hydrostatic system. In the subject arrangement, the speed of the pump input shaft and the speed of the motor output shaft is sensed (R,S) and the signals directed to a microprocessor which in turn processes the signals and directs a control signal (P) to a solenoid operated proportional valve. The solenoid operated proportional valve moves in response to the control signal and directs pressurized fluid to the displacement controller of the variable displacement pump to change the displacement thereof. Once the speed of the output shaft is achieved, the microprocessor modifies the control signal to maintain the variable displacement pump at the needed displacement position to maintain the desired speed of the output shaft to a work system. This arrangement provides an accurate control of the displacement of the variable displacement pump without the need of providing complicated follow-up mechanisms and/or servo mechanisms.

摘要： A valve range is suggested suitable for use in connection with the control of fluid operated equipment. It possesses a fluid manifold, which is able to be fitted with pneumatic valves, which are operated via a signal manifold electrically. The valve range is so designed that it is suitable for the combined operation or control both of pneumatic valves and also of hydraulic valves. For the control of hydraulic valves it is provided with at least one control connection, from which the respective control signals may be taken. It is in this manner that, starting with a central valve range both pneumatic and also hydraulic valves may be operated and controlled in a comparatively simple fashion.

摘要： A hydraulic system has a pump (1) with at least one load (4, 5) and accompanying bi-directional valves (8, 8a). A first comparator (A) establishes which motor line (6, 7) is carrying the higher load pressure. A second comparator (B) establishes whether the input-side motor line (6, 7) allocated a directional signal identifying the direction of the valve displacement is carrying the higher pressure or whether a load (4, 5) is being operated with negative loading. Depending on the result of the comparison, the load pressure signal (y1, y2) can be processed differently.

摘要： An apparatus controls a fluid system of a work vehicle. The work vehicle has an engine and at least one fluid circuit which has a pump driven by the engine. A plurality of control valves controllably pass fluid from the pump to a plurality of respective work elements. The control valves have movable valve stems. A work attachment which has a respective control valve is added to the fluid system. A plurality of operator control elements provide demand signals in response to selected settings. Each demand signal is indicative of a requested fluid flow to a respective work element or work attachment. A memory device stores select parameters of the fluid system. One of the select parameters is a predetermined priority value representing the precedence in which fluid is delivered from the pump to the control valve of the work attachment. A controller receives the predetermined priority value of the work attachment and the demand signals. The controller responsively determines the sequence in which fluid is distributed from the pump to the respective control valves. Then the controller delivers control signals to the rerspective control valves in response to the determination, selectively positioning the stem of the respective control valves.
