Characteristics of Experimental MSMA-Based Pneumatic Valves

Abstract

In the course of work on a linear actuator based on a magnetic shape memory alloy (MSMA), a research workstation was constructed enabling the examination of pneumatic valves featuring an electromechanical transducer created with MSMA technology. In this article, the general construction of the research workstation is presented, together with an initial study of a demonstrator of a pneumatic, one-stage, one-way throttle valve. In the presented demonstrator, a simple replacement of a electromechanical transducer into a transducer created with MSMA technology was performed. In addition, the study also describes the problems appearing in such structures along with potential troubleshooting methods.
