ABSTRACT:
A compression operated injector for delivering fuel directly to the combustion chamber of an engine has a piston which responds to the pressure in the combustion chamber and cooperates with a stepped plunger in the injector to pressurize fuel in both a control chamber and in an injector pump chamber. The discharge of fuel from the injection pump chamber for injection into the combustion chamber is controlled by a pressure operated valve. A solenoid actuated valve is used to control the escape of fuel from the control chamber so as to permit the piston to effect the necessary pressurization of the fuel in the injection pump chamber whereby to initiate the start of fuel injection.
