Patent ID: 7024742

Claim:
A rivet setting tool, comprising: a pulling head including a hydraulic piston disposed within a housing, said piston coupled to a jaw, the jaw operable to engage a rivet mandrel upon activation of the pulling head, whereby continued travel of the hydraulic piston supplies force to effectively set the rivet; a hydraulic pressure source connected to said housing by a hydraulic passage; a pneumatic intensifier operably coupled to the hydraulic pressure source; a hydraulic refill system coupled to the hydraulic pressure source configured to apply pressure to the hydraulic pressure source to cause the charging of the hydraulic passage, wherein the hydraulic pressure source comprises a ram housing and the pneumatic intensifier defines an intensifier chamber, said pneumatic intensifier further comprising an air piston disposed within the intensifier chamber coupled to a rod such that movement of the air piston causes translation of the rod within the ram housing and thereby applying hydraulic pressure to the hydraulic passage, and wherein the intensifier further comprises a baffle, said baffle dividing the intensifier chamber into a hydraulic fluid supply and a first chamber.
