Изобретение относитс  к машиностроению , а именно к гидравлическим демпферам, используемым при виброзащите точного оборудовани .The invention relates to mechanical engineering, in particular to hydraulic dampers used in the vibration protection of precision equipment.

Цель изобретени  - обеспечение стабильной характеристики.The purpose of the invention is to provide a stable performance.

На фиг. 1 изображен гидравлический демпфер, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows a hydraulic damper, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

Гидравлический демпфер содержит корпус 1, заполненный в зкой жидкостью , и поршень, выполненный составным по длине, части 2, 3, 4, 5 и 6 которого св заны пружинами 7, причем крайние части 2 и 6 жестко скреплень) со штоком 8, св зывающим поршень с колеблющимс  объектом 9, а средн   часть 4 поршн The hydraulic damper comprises a housing 1 filled with a viscous liquid and a piston made integral in length, parts 2, 3, 4, 5 and 6 of which are connected by springs 7, with the outer parts 2 and 6 being rigidly fastened to stem 8 a piston with an oscillating object 9, and the middle part 4 of a piston

при помощи стержней 10 жестко скреплена с корпусом 1 и основанием 11.. with the help of rods 10 is rigidly fastened to the housing 1 and the base 11 ..

При движении штока 8 вверх части 2, 3 и 4 поршн  расход тс , а части 4, 5, и 6 сближаютс v при движении штока вниз сближаютс  части 2,3 и А и расход тс  части 4, 5 и 6. Таким образом, независимо от направлени When the rod 8 moves upwards, parts 2, 3 and 4 of the piston are consumed, and parts 4, 5, and 6 approach each other; when the rod moves down, parts 2.3 and A approach each other and parts 4, 5 and 6 diverge. Thus, independently from direction

движени  штока 8 и колеблющегос  объекта 9 величина суммарного зазора между част ми поршн  сохран етс  посто нной, что обеспечивает посто нство коэффициента сопротивлени ,the movement of the rod 8 and the oscillating object 9, the magnitude of the total gap between the parts of the piston is kept constant, which ensures a constant resistance coefficient,

а следовательно, и линейную зависимость величины в зкого сопротивлени  от перемещений колеблющегос  объекта 9.and, consequently, the linear dependence of the magnitude of the viscous resistance on the displacements of the oscillating object 9.
