Claims
- 1. A fuel metering system effective for metering the rate of fuel flow to an associated combustion engine, comprising body means, conduit means formed in said body means communicating with a source of fuel, orifice means formed generally in said body means for receiving fuel from said conduit means and discharging said fuel into induction passage means associated with said engine, an opening formed in said body means, said opening receiving adjustably positionable valve means, said valve means being selectively adjustably positionable with respect to said orifice means in order to thereby cooperate with said orifice means in order to cooperatingly define an effective metering area for metering said rate of said fuel flow from said conduit means and to said induction passage means, and closure means received in said opening as to effectively close said opening to access to said valve means, said closure means comprising retainer means, a closure member operatively retained by said retainer means against withdrawal of said closure member from said opening, said closure member being rotatable with respect to said body means, said closure member comprising a first closure member body portion, a second closure member body portion, and an intermediate closure member body portion of transverse dimension less than that of either said first or second closure member body portions and operatively joining said first and second closure member body portions, an abutment surface carried by said body means, said retainer means being juxtaposed to said abutment surface, aperture means formed in said retainer, said intermediate closure member body portion being received in and through said aperture means as to cause said first and second closure member body portion to be respectively disposed on opposite sides of said aperture means, and each of said first and second closure member body portions being of a size and configuration precluding passage thereof through said aperture means once said intermediate closure member body portion is received in and through said aperture means.
- 2. A fuel metering system according to claim 1 wherein said abutment surface comprises a radially outwardly extending recess in communication with said opening.
- 3. A fuel metering system according to claim 1 wherein said retainer means comprises a C-type snap ring.
- 4. A fuel metering system according to claim 1 wherein said first closure member body portion comprises chamfer-like means thereon.
- 5. A fuel metering system according to claim 1 wherein said abutment surface comprises a radially outwardly extending recess in communication with said opening, wherein said retainer means comprises a C-type snap ring partly received in said recess, and wherein said first closure member body portion comprises chamfer-like means, said chamfer-like means enabling the engaging therewith and therethrough expansion of said aperture means as to enable passage of said first closure member body portion through said aperture means.
