Abstract

Improvements in fluid feeding devices under pressure of two receivers, such as hydraulic motors, consisting of: two receivers, a source of fluid under pressure, a flow divider, a discharge conduit that joins the fluid source to the inlet of the flow divider, two main ducts, each of them coupled, on the one hand, to one of the receivers, and on the other hand, to one of the two exit orifices of the flow divider, characterized in that it is endowed at each device of two auxiliary conduits that connect, one, one of the main conduits to the other inlet of the pressure addition device; a discharge duct, called the first delivery duct; a discharge flap, tared to a given and piloted tarrage, called the first discharge flap, which is disposed in the first discharge duct; and a splice joining the output member of the pressure addition device to the pilot member of the first tare discharge valve.
