Resumen:
Una universidad checa ha desarrollado el prototipo de un actuador lineal con válvulas de control hidráulico que permite un accionamiento hidráulico compacto. Este actuador consiste en un cilindro hidráulico diferencial con sensores de variables controladas, bloqueo de control con válvulas de control proporcionales separadas que permiten el control continuo de variables cinéticas y sistema de control integrado. Se buscan fabricantes de accionamientos hidráulicos, máquinas-herramientas, prensas, equipos de ensayo para analizar resortes, amortiguadores, etc. con el fin de establecer acuerdos de licencia.

Details

Tittle:
Linear hydraulic actuator with integrated control valves
Summary:
A Czech university developed a prototype of integrated linear hydraulic actuator. The university is looking for industrial partners who would be able to produce it. The university is looking for manufacturers of hydraulic controlled drives, manufacturers of machine tools and presses or manufacturers of test equipment for testing of springs, shock absorbers, etc. Cooperation is possible based on license agreement.
Description:
The linear actuator with integrated hydraulic control valves provides a compact hydraulic drive consisting of a differential hydraulic cylinder with sensors of controlled variables, control block with separate built-in proportional control valves enabling continuous control of kinetic variables and embedded control system with the control program.
The integrated linear hydraulic actuator enables:
· Control of the piston rod motion in an open regulatory circuit;
· Control of the piston rod position - realization of positional
servomechanisms;
· Control of the piston rod speed - realization of speed servomechanisms;
· Force control in the piston rod axis - realization of force servomechanisms;
· Combination of the above methods of control during the work cycle.
The integrated linear hydraulic actuator offers:
· Easy integration of the drive and autonomic control system into hierarchical control systems using industrial bus bars;
· Variability of drive functions enabling a choice from a higher control level;
· Transfer of the values of controlled variables to the higher control level.
Czech University offers Licence agreement cooperation.

Advantages and Innovations:
The integrated linear hydraulic actuator is characterized by:
· Compact design using built-in valves and original way of solution to the control block;
· Less weight and dimensions of the entire hydraulic circuit;
· Control variability via control valves in the bridge circuit;
· Option to select the control algorithm according to user applications;
· High-quality control compensating characteristics of the differential cylinder;
· Lower costs compared to traditional solutions.
