Abstract: An adjustment safeguard for a set screw on a carburetor includes a cap held non-rotatably on the head of the set screw. The cap is surrounded by a coaxially positioned wall sleeve fixed to the housing. A rotation stop is fixed to the housing to limit the angle of rotation of the cap in the sleeve in the rotational direction of the set screw. A through-opening in the cap permits inserting a tool into an engagement opening in the head of the set screw to avoid destruction by introducing too much torque into the adjustment safeguard. The form and opening width of the through-opening is limited by the use of a metal material such that a tool larger than the adjustment tool is not able to be inserted through the through-opening into the head of the set screw. The engagement opening is flexible to limit a maximum allowable adjustment torque.

Abstract: A carburettor includes a primary air passage (19), an adjustable throttle valve (8) situated within the primary air passage, a fuel supply nozzle (28) communicating with the primary air passage and connected to a fuel metering valve for varying the amount of fuel discharged through the nozzle. The fuel metering valve includes an elongate sleeve (32) movably accommodating an elongate valve member (33). The sleeve and valve member define a fuel inlet space (35). A fuel inlet (37) communicates with the fuel inlet space. A fuel outlet (39) passes through the wall of the sleeve (32) and communicates with the fuel supply nozzle (28). A portion of the outer surface of the valve member (33) is so profiled that the valve member (33) is movable relative to the sleeve (32) such that the area of communication between the fuel inlet space (35) and the outlet (39) varies progressively between a maximum and a minimum value.

Abstract: A carburettor including a primary air passage, an adjustable throttle valve situated within the primary air passage, a fuel supply nozzle communicating with the primary air passage and connected to a fuel metering valve for varying the amount of fuel discharged through the nozzle and a rotary input shaft adapted to be connected to an engine speed control member and which is connected to the throttle valve to move the throttle valve between open and closed positions. The rotary input shaft is also connected to a carriage to move the carriage, the carriage carrying at least one elongate inclined ramp which extends in the direction of movement of the carriage and which is engaged by a follower connected to the valve member. Rotation of the input shaft results in movement of the throttle valve and in movement of the carriage and thus of the elongate ramp, wherein the follower is moved transverse to the length of the ramp and the valve member of the fuel metering valve is thus also moved.

Abstract: An adjustment safeguard for a set screw that is rotatably held in a housing has a cap that is non-rotatably secured on the head of the set screw. The cap is received in a sleeve of the housing and surrounded with minimal radial play by the sleeve that is essentially coaxially positioned relative to the cap. The cap is received with its axial length in the sleeve. The cap has a projection and the sleeve has a stop arranged in the interior of the sleeve. Projection and stop interact with each other in a rotational direction of the set screw. The cap has a top part and a separate bottom part. The bottom part is secured axially and non-rotatably on the head of the set screw. The bottom part engages with form fit the top part in the rotational direction and is axially connected to the top part.

Abstract: In order to improve 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), extending in the transition area between the screw head (210) and the screw needle or valve needle (220) in a ring shape around the external circumference of the screw needle or valve needle (220), in particular for limiting the adjustment of the fuel flow through a carburetor (400; 400′), in such a way that inadvertently pushing the limiter cap onto the screw needle thus prematurely blocking said screw needle, already at the time when the (basic) carburetor adjustment takes place, is safely prevented, it is proposed that the limiting cap (300; 300′) is attached to each of the set screws (200) in particular in a way so as to be self-attaching, and/or in particular such that the limiter caps (300; 300′) engage each other with locking action, and/or without any further auxiliary means or without any further supplementary part.
