Regulator of pressure of fuel - the general data

The regulator of pressure of fuel consists of two chambers: fuel and диафрагменной. Fuel arrives in the fuel chamber through the entrance union. The diafragmennaja chamber is connected to the inlet pipeline. If pressure in the bottom chamber exceeds the total pressure created on a diaphragm by a spring and depression in the pipeline the diaphragm moves so that surplus of fuel could be returned back in a petrol tank on a returnable line. The regulator supports constant pressure difference in system at level of an order 2.5 bar.
