Abstract
A reservoir for a fuel injection system including an intermediate plate and a yieldable member movable relative thereto. The intermediate plate includes a flow opening and a throttle opening, the opening and closing of which are controlled by a valve. The valve is operatively connected with the yieldable member, which is biased toward the intermediate plate by a reservoir spring.
Claims5
A fuel reservoir for a fuel injection system, comprising:
- a housing defining a chamber;
- an intermediate plate mounted to the housing within the chamber for dividing the chamber into two parts, said intermediate plate having a flow opening and a throttle opening formed therein;
- a yieldable reservoir member mounted to the housing within one of the chamber parts and dividing that chamber part into two portions;
- reservoir spring means mounted within the chamber portion facing away from the intermediate plate and engageable with one side of the yieldable reservoir member, wherein the yieldable reservoir member lies against the intermediate plate in its rest position under the influence of the reservoir spring means;
- and
- valve means operatively associated with the flow opening and throttle opening in the intermediate plate, said valve means comprising:
- a movable valve member;
- and a valve spring engageable with the movable valve member in the opening position of the valve means when the reservoir experiences a movement to decrease its volume, said movable valve member including:
- (i) a shank member that projects through the flow opening and is displaceable by means of the yieldable reservoir member against the force of the valve spring;
- and
- (ii) a valve plate.
