Abstract
Improvements in gear pumps, of the type comprising a body provided with an inlet and an outlet for the fluid, the body of which delimits a profiled internal chamber, rotating gears located on the shafts, inside the body and having axially side faces separate, a thrust plate adjacent to at least one of the axially separated side faces, the thrust plate and the body delimit a luniform passages on the high pressure side of the pump and a preloading device adjacent to said thrust plate in opposite relationship with the side face, to initially maintain the thrust plate in a sealing relationship with the axially separated side face, characterized in that the thrust plate has openings through which the axes of the gears extend and which they are larger than the diameter of the axes, leaving the thrust plate free to float inside the camera in a lane perpendicular to the axis of rotation of said axes.
