Description

такт всасывани , а следовательно, и подача насоса завис т только от перепада давлени  на дросселе 9, задаваемого регул тором 10.the suction stroke and, consequently, the pump flow depend only on the pressure drop across the throttle 9 set by the regulator 10.

Дополнительна  емкость 11 переменного объема нозвол ет оптимально сочетать характеристики регулировани  изменением вредного объема с регулированием подачи внен1ним управл ющим устройс1вом.An additional variable-volume tank 11 makes it possible to optimally combine the characteristics of regulation by changing the harmful volume with the regulation of supply by an external control device.
