Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
The combination with an internal combustion engine having a fuel line, of a hollow chamber having generally aligned inlet and outlet openings at opposite ends and connected in series fluid communication in the fuel line adjacent to the engine, a mounting body extending into the hollow of said chamber in spaced confronting relation with said outlet opening, a valve stem slidably mounted in said body for longitudinal reciprocatory movement in substantial alignment with said outlet opening, a valve element on one end of said valve stem and movable therewith into and out of closing relation with said outlet opening, resilient drive means connected to said valve element for moving the latter into said closing relation, a retainer pin mounted in said mounting body for longitudinal sliding movement transversely of said stem for releasable retaining engagement therewith to effect closure of said valve element, and return means connected to said valve element for returning the latter to its open relation.
Claim 2
Dependent Claim
159 words
The combination with an internal combustion engine having a fuel line, of a hollow chamber having generally aligned inlet and outlet openings at opposite ends and connected in series fluid communication in the fuel line adjacent to the engine, a mounting body extending into the hollow of said chamber in spaced confronting relation with said outlet opening, a valve stem slidably mounted in said body for longitudinal reciprocatory movement in substantial alignment with said outlet opening, a valve element on one end of said valve stem and movable therewith into and out of closing relation with said outlet opening, resilient drive means connected to said valve element for moving the latter into said closing relation, a retainer pin mounted in said mounting body for longitudinal sliding movement transversely of said stem for releasable retaining engagement therewith to effect closure of said valve element, and return means connected to said valve element for returning the latter to its open relation.
Claim 3
Dependent Claim
26 words
The combination according to claim 1, said drive means comprising resilient compression means engageable with said valve means to urge the latter toward said closing relation.
Claim 4
Dependent Claim
25 words
The combination according to claim 1, in combination with a solenoid operatively associated with said retainer pin for effecting movement thereof from a remote location.
Claim 5
Dependent Claim
48 words
The combination according to claim 1, said return means comprising an arm extending generally rigidly with and transversely from said valve stem terminating externally of said chamber for manual access, said mounting body being formed with a slot receiving said arm and permitting movement thereof with said stem.
