The invention relates to a machine for descaling cells (3) of a cellular runoff body (2) used in an air-water exchanger, characterized in that it comprises at least one tool (6, 7) having an active tip (6a, 7a) and mounted on a frame (1) so as to be mobile between two positions in one direction common to all of the tools (6, 7) supported by the frame (1), the active tip (6a, 7a) of said tool being supported by the end of a rod (13) of a cylinder (11), the body (12) of which is mounted so as to be mobile relative to the frame (1) along the axis thereof, a piston (23) rigidly connected to the rod (13) and defining, in the body, a first chamber (26) which is constantly connected to a source of pressurized fluid and to a second chamber (27) through which the rod (13) passes, is in communication with the first chamber (26) as long as the rod (13) is at least partially retracted into the cylinder body (12) and insulated from the latter, and is connected to the exhaust when the rod (13) is in an end extension position outside the body (12).
A machine for descaling the cells of a cellular trickling-water body employed in an air and water heat exchanger, characterized in that it has at least one tool with an active tip and is mounted so that it can move on a frame between two positions in a direction shared by all the tools carried by the frame, the active tip of this tool being carried by the end of a rod of an actuator, the body of which is mounted so that it can move relative to the frame along its axis, a piston integral with the rod defining in the body a first chamber permanently connected to a source of pressurized fluid, and a second chamber through which the rod passes and which is in communication with the first chamber as long as the rod is at least partially retracted into the body of the actuator and isolated from the latter and connected to an outlet when the rod is in its furthest extended position outside the body.
