A fuel injector pressurizes fuel in a pressurization chamber and ejects the fuel from an orifice. A reverse flow check valve allows fluid communication between the pressurization chamber and the orifice during fuel injection, but blocks fluid communication between the pressurization chamber and the

대표청구항 ▼

1. A fuel injector comprising: a pressurization section at least partially defining a variable-volume pressurization chamber; a nozzle section having a check bore, a nozzle chamber, an orifice, a fuel injection check extending into the nozzle chamber and being slidably disposed in the check bore between a first position that blocks fluid communication between the nozzle chamber and the orifice and a second position that opens fluid communication between the nozzle chamber and the orifice, and a reverse flow check valve fluidly connected with the nozzle chamber; and a fuel passage fluidly connecting the pressurization chamber in the pressurization section with the reverse flow check valve in the nozzle section, the reverse flow check valve including a perforated reverse flow check hydro-pneumatically movable between an open position that allows fluid communication from the fuel passage to the nozzle chamber and a closed position that denies fluid communication from the nozzle chamber to the fuel passage; and wherein the fuel injection check extends through a perforation in the reverse flow check valve. 2. The fuel injector of claim 1, wherein the reverse flow check is ring-shaped. 3. The fuel injector of claim 1, the reverse flow check valve further including a clearance between the reverse flow check and the fuel injection check. 4. The fuel injector of claim 3, wherein said clearance fluidly connects the pressurization chamber with the nozzle chamber when the reverse flow check is in said open position. 5. The fuel injector of claim 1, wherein the reverse flow check is ring-shaped with a central perforation, and a column extends through the central perforation in the reverse flow check. 6. The fuel injector of claim 5, wherein said central perforation includes a clearance between the column and the reverse flow check that fluidly connects the pressurization chamber with the nozzle chamber when the reverse flow check is in said open position.
