ABSTRACT:
An injection valve assembly for spraying fuel into a diesel engine by receiving accurately metered charges of the fuel under pressure from an engine-driven jerk pump. The fuel inlet of the valve assembly communicates via a check valve with a storage chamber, where each incoming charge of pressurized fuel is stored temporarily. The fuel outlet of the valve assembly, in communication with the storage chamber, is normally closed by a spring-biased needle valve member. Upon full accumulation of each fuel charge in the storage chamber the check valve automatically closes the fuel inlet thereby causing the needle valve member to be displaced under the fuel pressure against the bias of the spring and hence to open the fuel outlet. Another embodiment employs two needle valve members, one for the on-off control of communication between the storage chamber and the fuel outlet, and the other for the on-off control of the fuel outlet.
