Conveying device for conveying a flowable medium

Abstract

The invention relates to a delivery device (1) for delivering a fluid medium, having a delivery drive (2), a pump device (3) and a scoop device (4). The delivery drive (2) is arranged at a first end (6) of a pipe (5), wherein the pump device (3) and the scoop device (4) are arranged inside the pipe (5). The scoop device (4) includes a foot valve (8), which is arranged at a second end (7) of the pipe (5) and which foot valve (8) serves to control an inlet (9) for an inflow of medium into a piston chamber (10). A piston (11), which sub-divides the piston chamber (10) into an inflow area (12) and a discharge area (13), is arranged in the piston chamber (10), wherein the inflow area (12) and the discharge area (13) are or can be connected via the piston (11), wherein the piston (11), via a piston rod (14), is movable between a retracted position and an extended position inside the piston chamber (10) by the delivery drive (2) (FIG. 1).
