(RU) ПЛОСКИЙ ТРУБЧАТЫЙ ГАСИТЕЛЬ КОЛЕБАНИЙ ДАВЛЕНИЯ ЖИДКОСТИ В ГИДРОЛИНИЯХ
Abstract
(EN)
FIELD: mechanical engineering; engines.SUBSTANCE: proposed flat tubular liquid pressure fluctuation damper is used in hydraulic lines for damping fluctuations of fuel pressure in vehicle fuel lines and is provided with at least one elongated chamber whose cross section is small, as compared with its length, and changes steplessly or in step in length and in which at least part of wall in contact with liquid can flexibly deform under action of fluctuations of pressure in this liquid. Chamber is formed by thin walled tubular element with closed ends made of steel sheet. Supply fuel pipeline is provided with at least one flat tubular liquid pressure fluctuation damper.EFFECT: provision of effective damping of fluctuations within wide range owing to stepless or stepped changing of cross section.5 cl, 3 dwg

Изобретение относится к двигателестроению, в частности к плоскому трубчатому гасителю колебаний давления жидкости в гидролиниях. Изобретение позволяет обеспечить эффективность гашения колебаний в широком диапазоне частот возбуждения пульсаций за счет плавного или ступенчатого изменения его поперечного сечения. Плоский трубчатый гаситель колебаний давления жидкости в гидролиниях, прежде всего колебаний давления топлива в питающих топливопроводах транспортных средств, имеющий по меньшей мере одну удлиненную камеру, поперечное сечение которой мало по сравнению с ее длиной и плавно или ступенчато изменяется по ее длине и по меньшей мере часть стенки которой, находясь во взаимодействии с жидкостью, имеет возможность упруго деформироваться под действием колебаний давления этой жидкости. Камера образована выполненным из стального листа тонкостенным трубчатым элементом с закрытыми концами. Питающий топливопровод оснащен по меньшей мере одним плоским трубчатым гасителем колебаний давления жидкости. 2 н. и 3 з.п. ф-лы, 4 ил.
