Abstract
Improvements in rotary pumps, characterized by comprising a box, rotating pump means mounted on the box, a drive shaft connected to the rotating pumping means and projecting from the box, intake and discharge conduits for the fluid to be pumped, a packing ring to prevent leakage of fluid from the box along the projecting part of the shaft and arranged in a stagnation chamber that extends around the shaft, and driving means that put the stagnation chamber in communication with the intake duct, to relieve the pressure of the fluid that flows along the shaft from the pumping means towards the packing, which means of conduction includes a passage extending along the shaft and radial holes in the tree that said passage in communication with the stagnation chamber, communicating said passage, on the opposite axial side of the pumping means with respect to the stagnation chamber, with the intake duct.
