    Abstract: The invention provides a variable displacement axial piston machine comprising a cylinder block with at least one main cylinder and main piston, a swash plate, a plunger arrangement with a plunger and auxiliary cylinder, and a sensor. The swash plate is arranged to effect movement of the main piston in the main cylinder upon rotation of the swash plate relative to the cylinder arrangement, the plunger being arranged to tilt the swash plate relative to the cylinder arrangement and thereby to control a stroke of the main cylinder In the main piston. To provide a simple and reliable measurement of displacement of the main piston in the main cylinder, the invention provides a sensor element which is fixed in the auxiliary cylinder and which is adapted to sense movement of the plunger therein.

    Abstract: The invention relates to a device and a method for controlling a two-cylinder thick matter pump comprising delivery pistons that are actuated in a push-pull manner by means of a hydraulic reversible pump (6) and hydraulic drive cylinders controlled by said pump. For each pressure stroke, the delivery cylinders (50, 50′) are connected to a delivery conduit (58) by means of a pipe junction (56). At the end of a pressure stroke, a reversal process of the reversible pump (6) and the pipe junction (56) is triggered. The aim of the invention is to obtain a targeted reversal of the reversal pump and the pipe junction, even when the deliverable quantity is varied, whereby the delivery cylinders are completely emptied, but also without pistons banging the ends of the cylinders. To this end, a computer-assisted reversal device is provided, said device comprising a measuring and evaluating routine for detecting the temporal displacement course of the piston along the path thereof between the two cylinder ends, by measurement and/or calculation, and for calculating a triggering time derived therefrom for the subsequent reversal of the reversible pump and the pipe switch.

    Abstract: A control system for controlling electromagnetic pumps, such as electromagnetic driven membrane pumps, has at least one microprocessor and at least one sensor, the microprocessor controlling the power supply to at least one electromagnet whose changes in emitted magnetic field causes at least one moving part, directly or indirectly, to perform an oscillating pumping movement. The control system has at least one positioning sensor which senses the moving part's position in the electromagnetic driven pump. By use of the positioning sensor's measurements, the pump can be controlled with great accuracy. A method for controlling electromagnetic pumps is also provided.

    Abstract: An active valve system may be used to improve operation of the suction valve(s) of a positive displacement pump. As appropriate, the active valve system may apply a force to the suction valve directed to open and/or close the suction valve. By quickening the opening and/or closing of the suction valve, the pump may run at a higher speed and operate with less wear. Additionally, the active valve system may allow all suction valves of a pump to be held open for various purposes.
