Abstract

473,746. Fuel injectors. BOSCH AKT.- GES., R. Feb. 17, 1937, No. 4733. Convention date, Feb. 17, 1936. Addition to 406,956. [Class 7 (iii)] To reduce the closing noise of the valve of the fuel injector described in the parent Specification, a non-return or other valve v is located in the fuelsupply passage t, close to the inlet of the fuel passage into the nozzle chamber, so as to throttle or prevent the return of fuel to the supply pipe during the closing movement of the needle valve b. The non-return valve v may be a ball or piston valve, and it may be located in the connection to the fuel pipe.
