Abstract:
A semi-automatic device for distributing compressed gas, comprising:a pneumatic jack comprising a cylinder, having a front and a rear end, wherein a piston, having a piston head and a rear end, can slide; a distributor, comprising a distributor support and a compressed gas intake means, wherein said distributor seals; said front end of said cylinder; a chamber having a front end, capable of containing a compressed gas, located between said distributor support and said piston head; means for successively and automatically carrying out the following operations after said rear end of said piston has been initially struck by a hammer: a forward displacement of the piston from an initial equilibrium position, thereby causing a compressed gas intake into said chamber and a pressurization of said chamber; a rearward recoil of the piston, thereby releasing said compressed gas from said rear end of said cylinder and depressurizing said chamber, said depressurization causing a closing of said compressed gas intake means; a return of the piston toward its initial position and a release of any remaining gas contained within the chamber from said front end of said chamber.
