Abstract
An accumulation type fuel injector is provided with an injector body and a needle valve guide having its one end fixed to the injector body. A nozzle body is fixed to the other end of the needle valve guide. The nozzle body is formed with an injection port and with an accumulation chamber. A needle valve is disposed in the accumulation chamber and is guided by the needle valve guide. A valve member is fitted in the injector body, and a check valve is guided by the valve member. A high-pressure fuel supply conduit is in communication with the accumulation chamber such that the needle valve opens when pressure in the fuel conduit is reduced. A controller guided by the valve member opens the check valve at the end of the fuel injection and a control piston guided by the injector body closes the needle valve.
