Abstract
Improvements in the apparatus for the opening of swing doors, characterized in that the leaf or component parts of a door, articulated laterally to the frame of the same, have between a point thereof and a fixed point of the frame, a cylinder pusher device for pressurized fluid in which the piston is externally related to a stop that operates inside a case mounted axially and articulated with the door, while that cylinder oscillates at said fixed point, having within said case a spring acting on the plunger and a contact for the microswitch, so that in the closed door position, said device remains inactive, while at the beginning of the opening of the door, under a certain thrust in one or the other direction, said stop is displaced that orients the cylinder and relates the own stop with the mentioned contact that determines the closing of an electrical circuit for activation of the reference cylinder, so that air or liquid under pressure flows into the cylinder to press the stop in the forward direction until reaching the front end of the box, where it produces a pressure that opens the door in the corresponding direction, after which fluid stops entering the cylinder and the stop moves back to return the door to the starting position.
