Abstract

Изобретение относитс  к машиностроению и может быть использовано дл  виброзащиты различного рода объектов, в частности дл  виброза- щиты стационарных измерительных систем. Целью изобретени   вл етс  повышение эффективности виброизол ции в низкочастотном диапазоне при любом направлении возмущающих воздействий и уменьшение габарита по высоте путем уменьшени  собственной частоты опоры и увеличени  отношени  обьема рабочей камеры к высоте опоры. При подаче воздуха через впускное сопло 12 давление в рабочей камере 1 повьшаетс  до величины, уравновешивающей вес изохшруемого объекта 18, при этом опорна  плита 5- гибкой диафрагмой 3 поднимаетс  вместе с выпускной 8 и впускной 9 заслонками до закрыти  впускного сопла 12. При увеличении нагрузки опорна  плита 5 с заслонками 8 и 9 смест етс  вниз, открыв доступ воздуха из пневмосети. При сн тии нагрузки между диафрагмой 3 и заслонкой 8 образуетс  зазор,черва который воздух выходит в атмосферу . 2 ил. (ЛThe invention relates to mechanical engineering and can be used for vibration protection of various kinds of objects, in particular for vibration protection of stationary measuring systems. The aim of the invention is to increase the vibration isolation efficiency in the low frequency range for any direction of disturbing influences and to reduce the height envelope by decreasing the natural frequency of the support and increasing the ratio of the volume of the working chamber to the height of the support. When air is supplied through the inlet nozzle 12, the pressure in the working chamber 1 increases to counterbalance the weight of the object 18 being sharpened, while the supporting plate 5 is flexible with the diaphragm 3 rising together with the exhaust 8 and the inlet 9 with flaps until the inlet nozzle 12 closes. plate 5 with flaps 8 and 9 is displaced downward, opening air from the pneumatic circuit. When the load is lifted, a gap is formed between the diaphragm 3 and the flap 8, the hole in which air escapes into the atmosphere. 2 Il. (L
