ES295233U - Perfected pneumatic hammer (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved pneumatic hammer, which is constituted from a steel cylinder, constituting a pneumatic cylinder in whose bosom a piston plays, a cylinder that ends at its front end in a toolholder, through which the corresponding pike emerges to the outside, while at the other end receives the classic handle, also made of steel, with interposition of the corresponding distributor, which accesses the pressurized air from the feed hose of the hammer, through a steering valve established in the handle and commanded by a trigger pivotally mounted therein, essentially characterized in that the classic neck of which the steel handle is provided for coupling to the pneumatic cylinder, has its smooth internal surface, like the corresponding sector of the cylinder, and is adapted to the latter by simple axial coupling, adjusted, while the final fixation between both pi ezas is carried out with the collaboration of a complementary retaining nut, provided at its front end with a slight throttle through which it hits a perimetral rim operatively established on the periphery of the pneumatic cylinder, said complementary nut having its other mouthpiece. Internally threaded and through which is attached to the one-piece collar of the handle and provided on its external surface with the corresponding complementary thread, all this so that this retaining nut, also made of steel, is enveloping the neck of the handle, stiffening structurally said neck.
