Abstract

Линейный привод, содержащий по меньшей мере один кожух (10), определяющий ось (X), и по меньшей мере один шток (20), имеющий торцевую цилиндрическую деталь (21), выполненную с возможностью сдвига с плотным прилеганием по меньшей мере в одном кожухе (10), и противоположный торец (22), сдвигающийся между положением покоя и рабочим положением. Торцевая цилиндрическая деталь (21) разделяет по меньшей мере один кожух (10) по меньшей мере на одну первую и вторую полости (18', 18") переменного объема, не связанные по текучей среде друг с другом, при этом одна из полостей (18', 18") изолирована по текучей среде и находится под вакуумом, тогда как другая полость (18', 18") находится в сообщении по текучей среде с внешней средой. При переходе противоположного торца (22) из положения покоя в рабочее положение одна из полостей (18', 18") меняет объем с минимального на максимальный, чтобы втянуть по меньшей мере один шток (20), автоматически возвращая противоположный торец (22) из рабочего положения в положение покоя.A linear actuator comprising at least one casing (10) defining an axis (X) and at least one rod (20) having a cylindrical end piece (21) capable of being displaced with a snug fit in at least one casing (10), and the opposite end (22), shifting between the resting position and the working position. The end cylindrical part (21) divides at least one casing (10) into at least one first and second cavities (18 ', 18 ") of variable volume, not connected by fluid with each other, while one of the cavities (18 ', 18 ") is insulated by fluid and is under vacuum, while the other cavity (18', 18") is in fluid communication with the external environment. When the opposite end (22) moves from the rest position to the working position, one of cavities (18 ', 18 ") changes the volume from minimum to maximum in order to retract at least one rod (20), automatically returning the opposite end (22) from the working position to the rest position.
