Description

Изобретение относитс  к детал м машин и может быть использовано в качестве гидравлического или пневматического силового цилиндра .The invention relates to machine parts and can be used as a hydraulic or pneumatic ram.

Известны цилиндры, между внутренней цилиндрической поверхностью которых и поршнем расположен эластичный уплотнительный трубчатый элемент, длина которого равна или превышает ход поршн .Known cylinders, between the inner cylindrical surface of which and the piston is an elastic sealing tubular element whose length is equal to or greater than the stroke of the piston.

Недостатком подобных устройств  вл етс  необходимость постановки байпаса между полост ми пространства, образованного вкладышем (трубчатым элементом) и цилиндрическим корпусом, разделенного поршнем, что усложн ет конструкцию устройства повышает его стоимость.A disadvantage of such devices is the necessity of placing a bypass between the cavities of the space formed by the liner (tubular element) and the cylindrical body separated by a piston, which complicates the design of the device and increases its cost.

Указанные недостатки устран ютс  в описываемом цилиндре за счет того, что вкладыш Имеет по меньшей мере одно отверстие, расположенное р дом с конечной позицией поршн , соедин юшее внутреннюю полость цилинд .ра с 1полостью между внутренней поверхностью цилиндрического корпуса и внешней поверхностью вкладыша.These drawbacks are eliminated in the cylinder being described due to the fact that the liner has at least one hole located near the end position of the piston, connecting the inner cavity of the cylinder with 1 cavity between the inner surface of the cylindrical body and the outer surface of the liner.

Предлагаемый цилиндр изображен на чертеже .The proposed cylinder is shown in the drawing.

Гидравлический или пневматический силовой цилиндр coiCTOHT из цилиндрического корпуса 1, внутри Которого расположен Поршень 2. Между цилиндрической поверхностью корпуса и лоршнем расположена эластична  уплотнительна  труба (вкладыш) 3, в котором выполнены р дом с конечной позицией поршн  отверсти  а.A hydraulic or pneumatic coiCTOHT power cylinder from the cylindrical body 1, inside of which piston 2 is located. Between the cylindrical surface of the body and the nozzle, there is an elastic sealing pipe (liner) 3 in which a hole is made near the end position of the piston.

При движении поршн  2 уплотнение осуществл етс  за счет .плотного контакта скругленного обода последнего с эластичным вкладышем 3. Присутствие в зазоре между вкладышем 3 и цилиндрической поверхностью корпуса 1 рабочей среды за счет наличи  отверстий а вызывает легкое нат жение трубчатого вкладЬгша, что .ведет к более плотному контакту поршн  с вкладышем.When the piston 2 moves, the seal is made due to the tight contact of the rounded rim of the latter with the elastic insert 3. The presence in the gap between the insert 3 and the cylindrical surface of the working medium body 1 due to the presence of holes a causes a slight tension in the tubular insert, which will lead to more tight contact of the piston with the liner.
