<p>The proposed devices comprise two hydraulic cylinders (1, 2) interconnected by a capillary (3) or other element (3) filled with a porous medium. Each of the hydraulic cylinders (1, 2) is formed by a piston (4, 5) mounted in its housing (6, 7) so as to allow the piston (4, 5) to slide under the action of a drive. Each of the hydraulic cylinders (1, 2) is provided with a pressure gauge (8, 9). Also provided are displacement gauges (10, 11) and a common base (12) on which are mounted the housings (6, 7) of the hydraulic cylinders (1, 2). The drive of the piston (4, 5) is so designed as to allow the piston (4, 5) to rotate by means of screw (13, 15) - nut (14, 16) pairs. The screw (13, 15) in each pair is connected at one end to the piston (4, 5) and at the other end to the motor (17, 18). The housing (6, 7) is connected to the nut (14, 16) by a flexible element (19, 20). The pressure gauge (8, 9) is designed as a connection between the displacement indicator and the nut (14, 16) and housing (6, 7), while the displacement gauge (10, 11) is designed as a connection between the displacement indicator and the piston (4, 5) and housing (6, 7) of the hydraulic cylinder (1, 2).</p> |
