Abstract
A delivery line for conveying viscous or pasty material to be filled into a food can or the like from a conveyor pump to a filling machine, having a delivery path developed in the form of a trombone tube with two sections extending parallel to each other and a U-shaped arch, the legs of which cooperate telescopically with the two sections. A pneumatic or hydraulic piston unit is provided to act on the U-shaped arch against the pressure of the filling material in the direction toward a shortening of the delivery path.
