Improvements introduced in vibrators by impact, characterized in that the first piston cylinder is internally jacketed and provided with ports coinciding with an annular groove made in the body of said piston-cylinder, which acts as an intercommunication chamber between the upper and lower chambers of the piston making it possible to assemble the sealing segments at the top of the machine; said piston cylinder has an exhaust port close to its bottom which is blind which is housed inside a second cylinder-piston and both cylinders supported by a strong antagonist.
