Abstract (en)
[origin: WO2019224244A1] The invention relates to an apparatus (1) for conveying thick matter (DS), having: - at least one drive cylinder (10a, 10b) for receiving hydraulic fluid (HF), at least one drive piston (11a, 11b), which is arranged in the drive cylinder (10a, 10b), at least one conveying cylinder (12a, 12b) for receiving thick matter (DS), at least one conveying piston (13a, 13b), which is arranged in the conveying cylinder (12a, 12b), and at least one piston rod (14a, 14b), which is fastened to the drive piston (11a, 11b) for coupling motion together with the conveying piston (13a, 13b), - wherein the drive cylinder (10a, 10b) has a rod-side opening (SDa, SDb) for applying pressure to a rod side (SKa, SKb) of the drive piston (11a, 11b) by means of hydraulic fluid (HF) and a floor-side opening (BDa, BDb) for applying pressure to a floor side (BKa, BKb) of the drive piston (11a, 11b) facing away from the rod side (SKa, SKb) by means of hydraulic fluid (HF), - a drive pump (20), which is designed to generate a drive volume flow (AVF) having a drive pressure (pA) of hydraulic fluid (HF) for moving the drive piston (11a, 11b), - at least one pump connection (30a, 30b), which is designed for variable connection of the drive pump (20) to the rod-side opening (SDa, SDb) or the floor-side opening (BDa, BDb) for the flow of hydraulic fluid (HF), - a sensor device (40), which is designed for automatic detection of whether the pump connection (30a, 30b) is connected to the rod-side opening (SDa, SDb) or the floor-side opening (BDa, BDb), and - a control unit (50), which is designed to control the apparatus (1) in a rod-side operating mode, when the rod-side pump connection is detected, and in a floor-side operating mode, when the floor-side pump connection is detected.
