Description

The invention relates to mechanical engineering, in particular to carburetor float chambers for an internal combustion engine.

The purpose of the invention is to simplify the design.

In Fig.1 shows the proposed float chamber of the carburetor for dvigmgelya internal combustion, section ·, figure 2 - section aa in figure 1.

The float chamber contains a housing 1 having side walls 2 and 3 and horizontal walls 4 and 5, the first of which forms the bottom of the float chamber, and 'the second - the cover, float 6 with a pivot arm 7, interacting with the fuel valve 8 located in the fuel supply channel 9 and mounted on the axis 10, and an adjusting screw 11, made with the head 12 (figure 2), located outside the housing 1, and installed in one of the side walls 3 of the housing 1. The axis 10 of the swing arm 7 is rigidly mounted on the end face 13 of the adjusting screw 11 axis eccentric rashchenija latter, forming a single piece screw 11 (the axis 10 can be performed and the adjustment screw 11 in one piece). The adjusting screw 11 is equipped with an oil seal 14 for sealing the internal cavity 15 of the float chamber, and also has a nut 16 for fixing in a certain position.

The camera operates as follows.

When the fuel level decreases below a predetermined level due to the flow rate, the float 6 lowers downward, turning together with the rotary lever 7 on the axis 10, and the fuel valve 8 opens the fuel supply channel 9, so that liquid fuel enters the internal cavity 15 of the float chamber, restoring the previous set level.

To regulate a given fuel level, unscrew the nut 16 and turn the adjusting screw 11 relative to the housing 1. Since the axis .10 is eccentrically located on the screw 11, it is displaced relative to the housing in the vertical direction. When the axis 10 is located in the lowermost 25 position, the specified fuel level in the inner cavity 15 is maximum, and with the highest upper position is the minimum. When the axis 10 is located in other intermediate positions, the set fuel level is regulated between the maximum and minimum values. After leveling the nut 16 fix the adjusting screw 11 relative to the housing.
