Abstract

Riveting traction gun, characterized in that it comprises: a body having two cylinders aligned axially; a piston assembly comprising two pistons connected in series, one in each cylinder, a clamping bolt in said assembly exiting one end of the body; a pistol grip attached to said body, provided with compressed air ducts comprising an open recess at the end of the stock that is fastened to the body; a slide valve assembly carried by said yoke and comprising a push-type trigger element guided in said yoke, and a slide valve secured to said element and movable in said recess; ducts in the body controlled by said slide valve in a position thereof, to vent said cylinders on their open sides to the sides of the pistons which, when subjected to the action of the compressed air, produce a recoil traction motion of said assembly, and a conduit for supplying a pressure flow to one of said cylinders in its open side to the side of the piston that returns the assembly to the projected position and, in the other position of the slide valve, venting said side of the cylinder and provides traction air pressure to the first mentioned sides of the two pistons; and in that said slide valve comprises a block having an elongated recess, the conduits in the body having two adjacent ports that are in communication with each other through said recess in the aforementioned position of the slide valve, the supply conduit being of pressure in communication with one of said ports through said recess in the other mentioned position of the slide valve.
