Abstract
Automatic closing mechanism for doors, characterized in that it consists of a pneumatic cylinder provided with an articulation device at one of the points to be connected, at one end, and a communicating passage with the outside, on which there is a regulating valve of passage of air, inside whose cylinder fits a piston, joined to a shank that protrudes sliding by the opposite end and ends in a fork between whose branches lodges a helical torsion spring, joined by one of its ends to the fork and on the other to an axis, rotating in aligned holes that present the branches of said fork and integral of a fixable support in the other point to connect with the mechanism.
