PNEUMO-HYDRAULIC DIGITAL DRIVE

摘要

The invention relates to devices of automation and can be used in mechanisms with discrete positioning of output circuit. A device has cylinder with hydraulic and pneumatic chambers with feeding channels, hydraulic volumetric dosers working chambers of which through three-position distributor and throttles with check valves are connected to hydraulic chamber of cylinder, decoder and linear displacement transducer output contacts of which are connected to contacts of electric magnets of three-position hydraulic distributor and input contacts to output contacts of electric decoder. The technical result is in simplification of construction and improvement of dynamical characteristics of the drive.
