Patent number: 11326592Abstract: A method for operating a hydraulic consumer on an electrically actuated control valve includes providing the valve with an open valve position for establishing a connection between a valve inlet and a pilot line for influencing a pivot angle set on an axial piston pump and a system pressure which is present at the valve inlet and dependent on the pivot angle. Data regarding the current system pressure and the current pivot angle are detected and communicated to a control unit. The method includes determining an incorrect setting of the control valve if the control unit detects that a delivery volume flow of the axial piston pump is smaller than a value to be expected based on valve position, or the control unit detects that the system pressure present at the valve inlet is at a maximum without a delivery volume flow flowing in the direction of the hydraulic consumer.Type: GrantFiled: July 18, 2019Date of Patent: May 10, 2022Assignee: DEERE & COMPANYInventors: Andreas Remmelmann, Christian Brueser

Patent number: 9599127Abstract: The invention relates to an system for supplying a hydraulic circuit with hydraulic fluid. The system includes a working reservoir and an auxiliary reservoir connected to the working reservoir by a hydraulic line. An air pump has an inlet connected to a suction line that opens into a liquid-free portion of the auxiliary reservoir so that a negative pressure can be built up in the auxiliary reservoir relative to the atmospheric ambient pressure. The air pump inlet is also connected to a control line, which comprises a control opening which is covered by the hydraulic fluid in the working reservoir, at least before the air pump is started up.Type: GrantFiled: January 21, 2014Date of Patent: March 21, 2017Assignee: DEERE & COMPANYInventors: Scott R. Wiens, Marcus Bitter, Christian Brueser, Harm-Hendrik Lange, Helmut Schaefer
