ABSTRACT:
The safety of a machine for cleaning tubes and pipes constructed so as to include an elongated cylinder, a piston located within the cylinder, a non-round piston rod attached to the piston so as to extend out of one end of the cylinder and hydraulic components for introducing a high pressure fluid into and out of the ends of the cylinder can be improved by providing a second cylinder which is located concentrically around the first cylinder. A discharge structure is attached to the second cylinder so as to be capable of venting or dissipating any fluid which may enter the second cylinder as a result of rupture of the first to the ambient surroundings. Preferably the discharge structure includes a pressure reducer such as an orifice and preferably the discharge structure is located so that any fluid discharged from it cannot cause damage.
