Маргелова" Министерства обороны Российской Федерации

Полезная модель относится к топливоподающей аппаратуре дизелей. Технический результат направлен на повышение эффективности двигателя и топливной аппаратуры путем предварительного подогрева топлива и его ионизации, увеличения давления впрыскивания топлива и крутизны фронта нарастания давления, что приведет к снижению температуры самовоспламенения топлива, качества распыливания топлива, улучшению пусковых качеств двигателя, более полному сгоранию топлива в цилиндрах и снижению дымности выхлопа, кроме того, увеличение давления впрыскивания и предварительный подогрев топлива дают возможность снизить степень сжатия, тем самым повысив индикаторное КПД дизеля. Технический результат достигается тем, что разрядная камера установлена около форсунки и система топливоподачи дизеля дополнительно содержит блок управления, размещенный в генераторе импульсов, с возможностью взаимосвязи управляющих сигналов блока управления с положением невозвратного клапана и нагнетательного клапана топливного насоса высокого давления, причем сигнал от невозвратного клапана обеспечивает возможность генерации теплового разряда, а сигнал от нагнетательного клапана - электрогидравлического разряда.

Provided are a valve body that sits on or separates from a seat; a plurality of guides that slidably guide the valve body; and a plurality of flow channel portions each formed between each guide adjacent circumferentially. Then, among the plurality of flow channel portions, the cross-sectional area of the first flow channel portion on a horizontal plane orthogonal to the central axis of the valve body is smaller than each of the cross-sectional areas of the remaining flow channel portions on the horizontal plane.
