Description
Изобретение относитс к двигателестроению , а именно, к устройствам дл защиты двигателей внутреннего сгорани от перегрева. Известны устройства дл защиты двигател внутреннего сгорани от пе регрева, содержащие датчик температуры , св занный через усилительнопередающий механизм с рейкой топливного насоса l. Однако в известных устройствах предусмотрена необходимость установки внутрь двигател датчика температуры , что затрудн ет его контроль и обслуживание. Цель изобретени - упрощение конструкции . Поставленна цель достигаетс тем Что датчик температуры расположен на наружной поверхности блока двигател и вьтолнен в виде биметаллической . пластины. На чертеже приведена схема устрой сува. Устройство содержит датчик 1 температуры , св занный через усилительно-передающий механизм в виде рычажной передачи с рычагами 2 и 3 и возвратной пружины 4 с рейкой 5 топливного насоса. Датчик 1 температуры расположен на наружной поверхности 6 блока двигател и выполнен в виде биметаллической пластины, снабженной регулировочным винтом 7. Устройство работает следующим образом . При Достижении предельной температуры поверхности 6 блока, биметал- лическа пластина датчика 1, изогнувшись на заранее установленный регу- . лировочным винтом угол, нажимает на рычаг 3, который освобождает рычаг 2. Рычаг 2 под действием возвратной пружины 4 перемещает рейку 5 топливного насоса в положение выключени подачи топлива. Использование устройства дл защиты двигател от перегрева позвол ет,FIELD OF THE INVENTION The invention relates to engine construction, namely, devices for protecting internal combustion engines from overheating. Arrangements for protecting the internal combustion engine from overheating are known, comprising a temperature sensor connected via an amplifier-transmission mechanism to the rail of the fuel pump l. However, in known devices there is a need to install a temperature sensor inside the engine, which makes it difficult to control and maintain. The purpose of the invention is to simplify the design. The goal is achieved in that the temperature sensor is located on the outer surface of the engine block and is made in the form of a bimetallic one. plates. The drawing shows the scheme of the device suva. The device comprises a temperature sensor 1 connected through an amplifying-transmitting mechanism in the form of a lever transmission with levers 2 and 3 and a return spring 4 with a rail 5 of the fuel pump. The temperature sensor 1 is located on the outer surface 6 of the engine block and is made in the form of a bimetallic plate, equipped with an adjusting screw 7. The device works as follows. When the maximum surface temperature of unit 6 is reached, the bimetallic plate of sensor 1 is bent at a pre-set dim. with the angle screw, it presses the lever 3, which releases the lever 2. The lever 2 under the action of the return spring 4 moves the rail 5 of the fuel pump to the off position of the fuel supply. Using a device to protect the engine from overheating allows
упростить исполнительный механизм и всю конструкцию в целом.simplify the actuator and the entire structure as a whole.
