FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to devices of adjust portion composition of mixture of gasoline designed to feed into internal combustion engine and it can be used in automobiles or power plants operating on different kinds of fuels for generating electric energy. Design peculiarity of proposed device is compact and simple design of rotary device connected with sender of microcircuit read off device. Proposed throttle valve position sender has housing made of non-conducting material and provided with flange and minimum pair of projections with round and oval holes, respectively. Outer surface of housing is provided with closed ribbing. Ring ribbing is provided along axis. Inner surface is base cantilever support with fitted-in rotary bushing. Projection of trapezoidal form is made in inner open ring surface relative to which bent off coil of spring is fastened. Spring is installed on surface of bushing and is locked in bushing by soil of spring bent in opposite direction. To hold bushing in initial position and to turn it through angle not exceeding 121°, opposite blind hole of bushing is provided with eccentrically displaced axis. Ring magnet rigidly coupled with bushing is fitted in blind hole coaxially to axis. Outer surface of bushing is furnished with second cantilever support made in combination cover provided with sender reading changes of magnetic field. Cross of bushing serves for connection with rod of throttle branch pipe which changes output voltage of microcircuit of sender with linear characteristic by means of ring magnet. Combination cover is glued to housing. Housing is provided with dummy branch pipe connected with sender of microcircuit. ^ EFFECT: enlarged operating capabilities of proportioning fuel flow sender in process of angular adjustment of position of throttle valve. ^ 4 dwg |
