摘要 |
A device for maintaining in a delivery pipe a working fluid under a determined pressure, using a source of pressurized auxiliary fluid communicating with a chamber of variable volume, in which the pressure of the auxiliary fluid varies in an inverse proportion with respect to the volume of the chamber. This device comprises an assembly of at least two jacks and at least one connecting rod articulated separately on first constituting elements of a first and a second jack of the assembly. The cylinder of the first jack is connected to the source of pressurized fluid and forms the chamber of variable volume and the cylinder of the second jack supplies the working fluid to the delivery pipe. |
