Patent application . . THROTTLE BODY FOR CARBURETTORS OF MOTOR VEHICLES

/ \ The present invention relates to throttle valves for carburetors, of in particular internal combustion engines for driving motor vehicles. .

It is well known that carburetors are subject to the risk of icing. The clubs - ■ The risk of soaking is particularly high when the outside air temperature is between 0 and + 8 ° C, because this is when the relative humidity is greatest. The for

amount of heat required to evaporate the fuel / is the throttle valve and withdrawn from their surroundings. This leads to local hypothermia and to Icing. · '·

Up to now, attempts have been made to counteract carburetor icing by heating the carburetor housing. The heating was done by means of cooling water or by heating the intake air through the exhaust manifold. _;

It has been found, however, that the measures taken are not effective enough to prevent the disruptive consequences, such as the motor stalling, in every case. -. "- '<..

It was found that the throttle itself was the starting point of icing

To remedy the deficiency described, in the manner according to the invention proposed the throttle valve itself with a heating device to provide.

In a preferred embodiment, the edge of the throttle valve provided with an electric heater. The heater can either consist of an electrical resistance wire or a similar electrical heater exist. ■; ■

As tests have shown, it is possible - with the heater according to the invention Already after 4 minutes of operation of the engine the throttle valve -j to bring the temperature to the temperature of the outside air. At idle. position (for example, in front of a traffic light), the temperature of the throttle valve can instantly increase to 60 °, so that etxia formed Eisansata on-the throttle immediately melts away. A stopping of the This prevents the motor. ■. ".. - -

Further details can be found in an exemplary embodiment that is appended to £ is represented by two figures. ·

Pig 1 shows the throttle valve according to the invention in a plan view,

partially cut. '■ "· ■'" '■ "..' :.

Pig 2 shows a section according to II - II of Pig 1.. .

The throttle valve is designated by 10 in its entirety in Pig 1 and 2. It can be rotated via the throttle valve shaft 11.

Reference numeral 12 denotes a heating wire which, as shown in Pig I, is fed to the throttle valve 10 through the bore 13 of the shaft 11. . . ■

The throttle valve 10 is provided with a groove 14 on its outer edge, see Pig 2. In this groove is the Heizdrahtseele 15, which is from
