Resumen:
Un instituto de investigación rumano ha desarrollado un equipo hidráulico rotativo con pistones axiales que puede emplearse en instalaciones hidráulicas para sincronizar los movimientos de varios mecanismos. Aunque en fase de diseño, se prevé que este equipo tendrá errores de cero y circulación bidireccional del fluido. Se buscan socios en el campo de investigación y producción para desarrollar el producto y transferir la tecnología.

Divider - adder for hydraulic flows
Summary:
A Romanian research institute has invented a rotary hydraulic equipment with axial pistons, which can be used for hydraulic drive installations, for the synchronization of motions at various mechanisms. Although this equipment is only in the concept stage, it is previewed to have zero dividing errors and a two-way circulation of the fluid.
The Institute is looking for partners in the field of research and production in order to develop the product and for technological transfer.
Description:
A Romanian research institute has developed a rotary hydraulic equipment with axial pistons, which eliminates the disadvantages presented by the gear hydraulic rotary dividers built on the principle of multiple pumps and slide valve and electromagnetic proportional control hydraulic dividers.
The divider-adder is made up of a tubular casing in which there is a rotor in a bearing on a hollow shaft, containing an odd number of axial pistons, each fitted on a cylindrical rod which can slide between two identical guide bushes, making each three compression chambers. Two of the compression chambers are equal in volume while the third one has a cumulative volume of the former two, that rest on a tilted disc in which an exit cap is pressed by the means of a cylindrical pin. The rotor is closed in the front side with two distribution caps that have two sets of distribution holes, in constant contact with an input cap, for the purpose of an accurate splitting of the flow into two equal flows on the travel direction, with the purpose of adding them together on the reversed travel direction, as an effect of the rotor spinning.
The Romanian research team is looking for EU partners (universities, institutes and SMEs), for research or technical cooperation agreements.
Advantages and Innovations:
- the dividing error is practically zero, because the splitting is done by the same piston that slides in the same slot and along the same stroke, half a turn to the left and the other half turn to the right;
- the divider-adder has a two-way circulation, acting as a flow divider in one direction and as a flow adder in the opposite direction;
- the same sized device can work with a wide range of flow rates, as the ratio of the extreme permissible internal rotative speeds is very high.
