<p>The invention relates to a testing stand meant to study the transient state in an electromagnetic actuator with volatile liquid. According to the invention, the stand consists of a support plate (4), which may rotate around a horizontal axle (3), the plate (4) may be immobilized in a certain position, as the case may be, in the conditions when on the plate surface there is mounted, by means of some rods (8 and 8'') and some threaded rods (9 and 9''), a device made of a transparent cylinder (10) partially filled with a volatile liquid (11), the cylinder (10) being closed at the lower part with a brass plate (14) which is in contact with a battery (15) of Peltier elements, and at the upper part it is closed with a mobile piston (12), sealed by a rubber gasket (13) and, for viewing the phenomena the transient state evolution depends on, at the actuator load operation, the piston (11), movable under the action of the vaporized liquid pressure, makes one piece with a rod (18), provided, at the upper part, with a plate (19), upon which there acts a helical spring (20), compressed by means of a thread rosette (21) which is moved inside a support (22).</p> |
