  • Load-sensing variable displacement pump controller with adjustable pressure-compensated flow control valve in feedback path
    Patent number: 4976106
    Abstract: A hydraulic switching system has an adjustable delivery volume pump connected to a pump regulating unit that is controlled by a load-sensing regulator. The load-sensing regulator is connected to a control pressure line that carries the maximum hydraulic energy consumer pressure required by at least one hydraulic energy consumer. The hydraulic energy consumer connected to the pump is controlled by a multiway valve having a given adjustment path. In order to increase the fine-controllability of the hydraulic energy consumer when desired, a pressure-compensated flow control valve which is located in the control pressure line is switched in and out of the system.
