<p>The invention relates to an energy regeneration process and a system of pneumatic drive for ascending and descending cyclic movements, meant to be used in mining, motor vehicles or naval industry. According to the invention, the process consists in using a closed-circuit pneumatic installation using a compressed gas, preferably nitrogen, as a working fluid to achieve an ascending motion, in which a gas within a recipient under a certain pressure is sucked by a pressure generator and delivered under higher pressure into a working chamber of a linear pneumatic motor, as well as a descending motion obtained by reversing the gas moving direction. The claimed system comprises a balancing beam (1) which has, at one end, a fixed hinge (2) provided with a mobile hinge (3) on which the rod of a linear pneumatic motor (4) is fixed, while, at the other end there is mounted a device for clamping the load in ascending or descending motion, and a pneumatic installation consisting of a distributor (5) provided with two electromagnetic coils alternately activated by an upper and a lower electric arrester, respectively, which can be switched to two positions, in the first position connecting a chamber of the pneumatic motor (4), corresponding to the large surface of a piston, to the delivering end of a pressure generator (6.1) and one or several pressurized gas recipients (7) to the suction end thereof, in order to achieve the ascending motion, while, in the second position of the distributor (5) the gas moving direction is reversed, some pressure gauges (8 and 9) for measuring the maximal and minimal pressure, a safety valve (10) to provide protection against incidental overpressure, an auxiliary pressure generator (17) for the nitrogen, as well as a control system which monitors the operation of the installation.</p> |
