3. OPERATION
In the course of operation fuel gets to the inlet space of housing (1) (Ref. Fig. 1). On passing through the
mesh of filtering element (3), fuel is cleaned of mechanical impurities, flows to the filtering element inner space
and is fed to the engine through the filtering element outlet hole.
If the filtering element gets clogged and fuel pressure difference on it is
(0.1±0.02) kgf/cm , the by-pass fuel opens and fuel passes through the holes in disk (7) from the housing
space to the filter outlet hole by-passing the filtering element.
