The present invention proposes the use of a tool () that is connected to a device for locomotion, such as, for example, a robot, and provided with an umbilical cable () to bring about a controlled reaction near the blockage, in order to remove it. In order to carry out that controlled reaction, an injection, and control system is used, which may be a closed loop control system.

System for unblocking or cleaning ducts by means of a controlled local reaction

A low-temperature turbocompressor structural arrangement for an internal combustion engine for using energy that is available but unused during operation to cool the air supplied to the engine by supercharging. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine. The structural arrangement may be mounted in full or in part, and also each component may be fitted into existing systems.

Structural arrangement in a low-temperature turbocompressor using other power connections

The present invention relates to an intervention drive pig comprising an umbilical. In this scenario, the present invention provides an intervention drive pig comprising an umbilical, wherein the umbilical () is manufactured from a low-density material, wherein the umbilical () comprises an external covering of material having a low coefficient of friction.
