Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A fuel valving apparatus for an internal combustion engine which has a cylinder defining a combustion chamber in which a piston is movable, comprising a cylinder head closing the combustion chamber, said head having a top opening with an injection port extending from the top opening into the combustion chamber and defining an intermediate chamber communicating with said injection port, a cylindrical hollow valve holding portion positioned in an opening above the intermediate chamber and having a valve seat, a valve body movable in said valve holding portion having a flange portion engageable and disengageable with said seat so as to position said valve body in respective closed and open positions, said valve body having an interior vaporizing chamber which communicates with said intermediate chamber when said valve body is opened, fuel injection means connected through said valve holding portion communicating with said intermediate chamber when said valve body is closed, and drive means engageable with said valve body to move said valve body between closed and opened positions.
Claim 2
Dependent Claim
169 words
A fuel valving apparatus for an internal combustion engine which has a cylinder defining a combustion chamber in which a piston is movable, comprising a cylinder head closing the combustion chamber, said head having a top opening with an injection port extending from the top opening into the combustion chamber and defining an intermediate chamber communicating with said injection port, a cylindrical hollow valve holding portion positioned in an opening above the intermediate chamber and having a valve seat, a valve body movable in said valve holding portion having a flange portion engageable and disengageable with said seat so as to position said valve body in respective closed and open positions, said valve body having an interior vaporizing chamber which communicates with said intermediate chamber when said valve body is opened, fuel injection means connected through said valve holding portion communicating with said intermediate chamber when said valve body is closed, and drive means engageable with said valve body to move said valve body between closed and opened positions.
Claim 3
Dependent Claim
39 words
A fuel valving apparatus according to claim 1, including a heating element extending through said valve body and into said vaporizing chamber, said valve head and said intermediate chamber comprising a hemispherical precombustion chamber communicating with said injection port.
Claim 4
Dependent Claim
97 words
A fuel valving apparatus according to claim 1, wherein said valve holding portion comprises a sleeve positioned in the opening of said head, a guide sleeve arranged inside said sleeve, said valve body being in slidable engagement with said guide sleeve and having a widened portion at its lower end in sliding engagement with said sleeve, said sleeve having a flanged lower end portion forming a seat for said valve body, said valve body having a flange portion engageable with said seat, said vaporizing chamber having thin portions therein and said heater extending into said vaporizing chamber.
Claim 5
Dependent Claim
153 words
A fuel valving apparatus according to claim 1, wherein said valve body is hollow, a shaft slidable in said hollow portion of said valve body and having a widened shaft portion and a narrow shaft portion adjacent its lower end, means for rotating said shaft, said valve body having a fuel injection port extending from its exterior into the hollow portion thereof in which said shaft is positioned, said fuel injection means comprising an opening in said valve holding portion, an injection nozzle extending through said opening, said valve body having a widened portion positionable at the opening of said valve holding portion slidable with the fuel injection portion on said valve body for the passage of fuel through said valve body to the hollow interior, the hollow interior opening into said intermediate chamber, said shaft being rotatable to rotate the amount of fuel injected through the hollow passage of said valve body.
Claim 6
Dependent Claim
85 words
A fuel valving apparatus according to claim 1, wherein said vaporizing chamber is of uniform diameter, said valve body including a widened portion disposable in said vaporizing chamber and a shank portion of lesser diameter than said widened portion, said valve holding portion having a fuel injection opening of said vaporizing chamber to the exterior, said fuel injection means including a fuel nozzle extending into the opening, said opening being blockable by positioning the widened portion of said valve body over the fuel injection opening.
Claim 7
Dependent Claim
70 words
A fuel valving apparatus according to claim 1, wherein said valve body includes a fuel passage therethrough, a control sleeve member positioned around said valve body in said valve holding portion, said fuel injection means including a nozzle for fuel extending through said valve holding portion into said vaporizing chamber, said fuel control sleeve having an opening communicating with said vaporizing passage through the internal passage of said valve body.
Claim 8
Dependent Claim
34 words
A fuel vaporizing apparatus according to claim 1, wherein said valve body also includes a blocking member for blocking the opening of said fuel injection passage when said valve is in an open position.
Claim 9
Dependent Claim
61 words
A fuel valving apparatus according to claim 1, wherein said valve body includes a triangular intermediate portion located in said vaporizing chamber followed at its lower end by a flange portion and including an opening through said valve member extending from said intermediate passage upwardly through said valve body at a right angle into said triangular portion to said vaporizing chamber.
