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 comm
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).

1. A machine for descaling the cells of a cellular trickling-water body employed in an air and water heat exchanger, the cells having a longitudinal direction, the machine comprising at least one tool, with an active tip, mounted so that the at least one tool can move on a frame between two positions in the longitudinal direction, the active tip being carried by an end of a rod, a body of an actuator being mounted so that it can move relative to the frame along a longitudinal axis of the rod, 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 fluidic 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, wherein the body of the actuator is movably connected with respect to the frame by means of a carriage mounted so as to slide on the frame in a direction parallel to the axis of the actuator, the connection between the carriage and the actuator body being elastically extendable along this axis over a specified and self-adjusting amplitude in a plane perpendicular to this direction, andwherein the abovementioned connection has a plurality of inelastic and deformable upper and lower links forming stays between the carriage and the body of each actuator, the length of the links being such that, when the upper links are straight, the lower links are bent and vice versa, the break points of the links being joined by elastic members which effect the suspension of a needle on the carriage with a specified degree of tension in the links. 2. The descaling machine as claimed in claim 1, wherein communication between the first and second chambers of each actuator is effected by a clearance between the body of the actuator and the piston. 3. The descaling machine as claimed in claim 2, wherein a permanent leak is created between the body of the actuator and the rod so that the second chamber is connected to the outlet by this leak. 4. The descaling machine as claimed in claim 3, wherein the cross section of the abovementioned leak is much less than the abovementioned clearance between the body and the piston so that the pressure (P) of the source can be established in the second chamber. 5. The descaling machine as claimed in claim 4, wherein the piston isolates the second chamber from the leak around the rod by means of a seal with which it is provided and which, in the maximally extended state of the rod, is in contact with the base of the body of the actuator through which the rod passes. 6. The descaling machine as claimed in claim 1, wherein the links are cables. 7. The descaling machine as claimed in claim 1, wherein the links are levers articulated together at the break point and respectively at the body of the actuator and at the frame at their free ends. 8. The descaling machine as claimed in one of the preceding claims, wherein each actuator rod is guided relative to the frame by means of a guide integral with the frame having a self-adjusting connection in a plane perpendicular to the axis of the rod. 9. The descaling machine as claimed in claim 1, wherein the rod is arranged to be inserted into the body of the actuator when a resistance force applied to the tool exceeds a threshold. 10. The descaling machine as claimed in claim 1, wherein the active tip causes a local expansion of the cell.
