ABSTRACT:
A gasoline unit injector comprising an outer, electrically conductive bellows, defining a variable volume fluid chamber, for reciprocating a piston within a pressure chamber to increase the fuel pressure in various downstream cavities. Various bellows are disposed within such chambers and are deformable in response to the increased pressure, the bellows are operative to control the rate at which fuel flows out from a metering orifice upon activation of a coil assembly.
