Abstract (en)

[origin: EP0787563A1] A hydropneumatic riveting gun (1) comprises a handle (2) at the top of which there is a single-acting hydraulic cylinder (3) that acts on a rod (5) having a threaded end (5a) designed to hold a threaded rivet. A pneumatic cylinder (4) mounted under the handle (2) is envisaged to drive the hydraulic cylinder (3) upon operation of a trigger (7) located on the handle (2) whereby a source of fluid under pressure can be connected to a lower chamber (4b) of the pneumatic cylinder so as to drive the hydraulic cylinder (3). The pneumatic cylinder (4) is equipped with a pressure reducing valve (30) which regulates the delivery pressure to the said lower chamber (4b). <IMAGE>
