Patent ID: 7097164

Claim:
A limiter cap ( 300 ; 300 ′) for limiting the adjustability of at least two set screws or valves ( 200 ), which are arranged side by side, with each set screw or valve ( 200 ) comprising at least one retaining nose or stop leg ( 240 ), which in the transition area between the screw head ( 210 ) and the screw needle or valve needle ( 220 ) extend in a ring shape around the outer circumference of the screw needle or valve needle ( 220 ), for limiting the adjustment of the fuel flow through a carburetor ( 400 ; 400 ′), wherein said limiter cap ( 300 ; 300 ′) can be attached to any of the set screws ( 200 ); comprises at least one adjustment prevention device ( 330 ), comprising at least one end stop ( 332 , 334 ); can be attached to the set screw ( 200 ) so that the limiter cap ( 300 ; 300 ′) surrounds at least a region of the set screw ( 200 ) essentially so as to be positive-locking; and in a first installation position, in which the set screw ( 200 ) can be rotated relative to the limiter cap ( 300 ; 300 ′), can be attached in a captive way to the set screw ( 200 ); and in a second installation position can be locked in a captive way to the set screw ( 200 ) by way of at least one locking means ( 250 ), by way of at least one serration profile, by way of at least one knurl; characterised in that attachment of the limiter cap ( 300 ; 300 ′) on each of the set screws ( 200 ) takes place in a self-attaching manner and/or such that the limiter caps ( 300 ; 300 ′) snap into each other, and/or without any further auxiliaries or supplementary parts; and that each of the limiter caps ( 300 ; 300 ′) comprises at least one guiding nose ( 352 ) and at least one connection groove ( 324 ) such that in the first installation position, the guiding nose ( 352 ) of one limiter cap ( 300 or 300 ′) engages the connection groove ( 324 ) of the other limiter cap ( 300 ′ or 300 ) which is attached to the adjacent set screw ( 200 ); and in the second installation position the guiding nose ( 352 ) jumps back below the stop leg or the retaining nose ( 240 ).
