Description
В существующих пнев-матических регул торах состава смеси дл устранени обогащени смеси в авиационном двигателе по достижении определенной высоты полета высотна мембрана должна обеспечивать обогащение состава смеси только до определенной высоты, однако в силу своей конструкции работа высотной мембраны не может изменитьс , а -потому и обогащение состава смеси будет :продолжатьс выше расчетной высоты. Такое положение вл етс ненормальным, поскольку это способствует падению мощности двигател , которое в свою очередь влечет к падению скорости, снижению высотности и дальности полета самолета.In existing pneumatic mix composition regulators to eliminate enrichment of the mixture in an aircraft engine, upon reaching a certain flight altitude, the high-altitude membrane should only enrich the composition of the mixture to a certain height, however, due to its design, the high-altitude membrane cannot change and therefore enrich the composition of the mixture will: continue above the calculated height. This situation is abnormal because it contributes to a drop in engine power, which in turn leads to a drop in speed, a decrease in altitude and range of the aircraft.
Насто щее изобретение направлено к устранению указанного недостатка .путем введени приспособлени з конструкцию пневматического регул тора.The present invention is directed to the elimination of this drawback by introducing a device with a pneumatic regulator design.
Предлагаемое приспособление характеризуетс применением дополнительного анероида, реагирующего на изменение атмосферного давлеНИ и служащего, с помощью своего щтока, дл ограничени сжати мембраны, реагирующей на разность давлений атмосферного и за нагнетателем.The proposed device is characterized by the use of an additional aneroid that reacts to changes in atmospheric pressure and an employee, using its own brush, to limit the compression of the membrane, which reacts to the difference in atmospheric pressure and behind the supercharger.
На чертеже изображен вертикальный разрез пневматического регул тора .The drawing shows a vertical section of the pneumatic controller.
В высотной мембране 1 установлены направл юща втулка 2 и щток 3 с пружиной 4 на щток 3 опираетс анероид 5 с выкачанным из него воздухом.In the high-altitude membrane 1, a guide bushing 2 and a brush 3 with a spring 4 are mounted on the brush 3 an aneroid 5 is supported with air exhausted from it.
Нри работе высотна мембрана 1 испытывает по наружной поверхности давление за нагнетателем, а по внутренней поверхности давление окружающей среды (атмосферное).In operation, the high-altitude membrane 1 experiences pressure downstream of the supercharger along the outer surface, and ambient pressure (atmospheric) along the inner surface.
При работе двигател в полете возможны -перепады давлений в сторону сжати высотной мембраны 1. Такое направление деформации мембраны должно вызвать обогащение смеси,When the engine is in flight, there are possible pressure drops in the direction of compression of the height membrane 1. Such a direction of deformation of the membrane should cause an enrichment of the mixture,
По мере подъема самолета на высоту необходимо получить обеднение смеси, в этом случае вступает в работу предлагаемое приспособление .As the plane rises to a height, it is necessary to get a lean mixture, in this case, the proposed device comes into operation.
