Abstract
A device (1) for introducing a plugging compound (20) into a borehole (21), the device having a sleeve (2) with a cavity (3) for receiving the plugging compound (20). On one side, the sleeve (2) has a discharge opening (5), corresponding to the cavity (3), for discharging the plugging compound (20), and a support section (7), projecting laterally from the sleeve, for providing a support option for the sleeve (2) during introduction of the plugging compound (20). On the opposite side of the sleeve (2), an upper opening (4) is provided, through which a piston (16) together with a feed plate (18) protrudes into the cavity (3). The piston (16) is movable relative to the sleeve (2) in such a way that the feed plate (18) can be displaced in the cavity (3), for example to allow the plugging compound (20) to be received and dispensed.
