Improvements in the manufacture of door dampers, characterized in that the impulse received in the door by the action of an auxiliary spring independently mounted, is cushioned thanks to the combined operation of mechanical and pneumatic elements that essentially consist of a cylinder within which a piston is slid, provided with sealing means, pushed by a lever or rod that is related, at the same time, to a support element, so that said piston compresses the air present in said cylinder, letting it escape slowly through of a suitable outlet orifice known per se, so that the door closes smoothly and finishes closing by the final action of the auxiliary spring.
