“…Theoretical and experimental researches were carried out for many years within the Mechatronics and Precision Mechanics Department of "Politehnica" University of Bucharest in the field of hydraulic proportional units with mechanical position feedback. Two experimental models with external position feedback, developed by the authors, are presented in [2] and [3].…”

The paper presents the actual stage of hydraulic positioning units with external mechanical position feedback and proposes an original design of a hydraulic positioning unit with internal mechanical position feedback, developed by the authors. The design of the positioning unit is discussed in order to obtain a compact system with low sizes, the built experimental model is described and some results of a first set of experimental tests are presented.

“…The system allows for multiple functions, such as: -positioning a load with specific precision at any point of the work run [5]; -data acquisition for functional parameters (pressures, temperatures, mass flows) and their comparison with data obtained from numeric simulation; this ensures verification for the developed mathematical model; -adjustment of load speed at the desired value and keeping that speed constant even with the resistant force varying over time.…”

Abstract. In driving systems using working fluids, for monitoring the fluid's parameters such as pressure, flow and temperature appropriate transducers are present in different areas of the system. Such an approach has certain disadvantages with regard to the installation and powering of the transducers as well as the transmission of the signals supplied by the transducers to the system's electronics command block. Both hydraulic and pneumatic driving systems are considered. The paper proposes a sensor block which integrates the above mentioned sensors and eliminates the previously outlined disadvantages. The proposed block can be designed for an easy installation in a driving system containing a pneumatic linear motor; basically for a standardised motor one of the caps is replaced with the proposed block. An example is also shown for the integration of the proposed block in the structure of a pneutronic system.
