The object of the present invention is a pressure converter / multiplier for use in situations in which you work with two different hydraulic fluids and it is not permissible mixing thereof. The purpose is to get pressure and flow with a special fluid of which no installation is available hydraulics.

The converter / multiplier, object of the invention It is of compact structure and allows to generate a pressure in one of the chambers depending on the pressure applied in the other. He objective is to be able to generate pressures with any fluid starting of the own of an installation. In addition to the pressure you can Also check the output flow. It is characterized because presents compact structuring and modular configuration consisting from:

a) two similar modules arranged so speculate and joined by a single, double piston shaft, in which modules two different hydraulic fluids are used and so independent, which allow the control of the pressure and flow in the said chambers;

b) an intermediate module that joins the two modules each other and has the aforementioned single double piston shaft;

c) means for anchoring the assembly a land.

The priority application of this converter / multiplier is in the duration tests at hydraulic actuators within the aeronautical sector. In this sector uses a hydraulic oil that, due to its different compressibility characteristics, viscosity, etc. is considered Very stable for use. It is also a very fluid corrosive that requires special instructions utilization. The tests / tests that are applied on components aeronautics that use this fluid, are carried out in facilities that handle a different hydraulic fluid, more conventional, cheap and less corrosive. An installation for the realization of tests / tests with an exclusive circuit for hydraulic oil very corrosive would be very expensive, both in the development phase and construction as in maintenance. It is also very important to ensure that these two fluids do not mix to avoid thus the contamination of their respective hydraulic circuits.

The converter / multiplier allows, in one Easy and cheap way, ensure that the two fluids do not mix since it prevents physical contact between them.

The advantages of this new converter / multiplier are evident:

- Allows the control of the Pressure or Flow in a hydraulic line

- Allows to guarantee that there is no contact physical between two fluids, which achieves non-contamination thereof.

- It is very manageable and easy to assemble.

- Allows identification in case of leakage of the corresponding fluid.

An example of practical, non-limiting embodiment of the present invention.

The elements of which this device consists They are:

- The module (1) with shut-off valve, being able to be proportional to generate different pressure states or flow.

- The module (2) arranged in a specular way regarding the module (1).

- The module (3) with drainage system fluids and ground anchor (5).

- The single axle (4) is double piston and guarantees their alignment.

- The corresponding meetings, necessary for prevent fluid leaks between the elements of the assembly complete the structuring of the converter / multiplier of pressures without mixing fluids, object of the invention.

By the inlet valve of one of the two sides of the converter / multiplier the fluid (F1) base is introduced of the hydraulic installation. Said fluid (F1) is introduced into the chamber (C1) of the module (1) at a pressure and with a flow determined to be transmitted through the shaft (4) with two pistons to the chamber (C2) of the module (2) arranged in a specular manner.

This axis (4) is the same for both cameras (C1), (C2) or two axes that are joined in such a way that it is possible to transmit the pressure from one chamber (C1) to the other (C2). A third hollow module (3) serves to join the two modules (1), (2) earlier making the set more compact. Also this module (3) is equipped with a drainage system for collecting possible leaks in the chambers (C1), (C2) of the modules (1) and (2).

The arrangement of the modules (1), (2), (3) makes the converter is self-supporting and an anchor is not necessary (5) complicated set to support the load generated by the shaft movement This anchor (5) is made by legs placed in modules (1) and (2) and only serves to fix the set to the ground.

In the case of being used as a converter the modules (1) and (2) will have the cameras of identical section while that if it is used as a multiplier the module chamber (2) must be of a smaller diameter, and with a relation of areas inversely proportional to the relationship of pressures that you want to achieve.
