ABSTRACT OF THE DISCLOSURE A horizontal fluid-operated motor wherein the foremost end of the horizontal piston rod is connected with the feed ram of an incinerator and with the front end portion of a hollow tubular shroud which spacedly surrounds the piston rod in each axial position of the latter and whose rear end portion permanently surrounds but is movable axially of the cylinder of the motor. The cylinder and the shroud define a narrow ring-shaped clearance which admits air into the interior of the shroud when the piston rod performs a forward stroke and which permits expulsion of air from the interior of the shroud when the piston rod performs a return stroke whereby the outflowing air entrains impurities which might have penetrated into the shroud. The shroud extends, without any or with minimal clearance, through the opening of a transverse wall at the front end of the cylinder.
