The regulator of pressure of giving of fuel 19 (fig. 201) represents мембранный перепускной the valve and is established on the end of a fuel distributive highway 6. On a regulator diaphragm pressure of fuel, and on the other hand pressure of a spring of a regulator and pressure (or разряжение) in an inlet pipe on the one hand operates. Regulator function consists in maintenance of constant pressure difference on an atomizer 10.

The regulator of pressure of fuel is connected through a hose with the case throttle заслонки and reacts to pressure decrease in an inlet pipe. At pressure reduction in an inlet pipe (it is less opening throttle заслонки) the regulator reduces pressure of giving of fuel. Thus the regulator valve opens, and superfluous fuel on a drain highway merges back in a fuel tank. At increase in frequency of rotation of a cranked shaft pressure in an inlet pipe increases also a regulator increases pressure of giving of fuel.
