The paper is devoted to the research of pneumatic membrane probes containing membrane based rod that runs a function of the hard centre. They are widely used in engineering as shut-off and control apparatus machine, chemical, oil gas and other industries. The influence of the rod support parameters on the stiffness characteristic of the rod stroke from the payload is analysed. The operation methods of membrane drives are considered. The possibility of enhancing their efficiency by using the effective membrane area is shown. The authors applied a method in which the effective area of the membrane is used during the drive operation by adjusting the bending stiffness of the support. A device has been developed in which the support is made in the form of a limiter for the flexural deformation of a membrane and an autonomous elastic shell forming a hermetic chamber connected to an overpressure pneumoline. Field studies of a single-membrane pneumatic drive were carried out on a laboratory setup. Studies have confirmed the industrial applicability and effectiveness of the developed technical solutions. In a drive with a membrane made of IPR-1266 rubber, 1 mm thick, 105 mm in diameter, and a camera with a diameter of 62 mm, its stiffness characteristic significantly increases. Compared with the traditional membrane drive, this characteristic is enhanced by more than three times.
