Abstract
The present utility model relates to a carburettor anti-fire system, the format of which has been conceived and designed to ensure the safety of ultralight aircraft, preventing accidents resulting from the unintentional firing of the engine of the paramotor during the actuation thereof, on the ground or on the back, thus preventing the pilot from being struck by the propellor.
Description
“SISTEMA ANTI DISPARO DE CARBURADOR” “CARBURETTOR ANTI-TRIGGER SYSTEM”
Sistema Anti Disparo de Carburador, patente de Modelo de Utilidade, diz respeito a um dispositivo que impede o acionamento involuntário, com aplicação na área de carburadores para motores á combustão de dois ou quatro tempos, visando interromper o funcionamento do motor, caso, por qualquer motivo, o motor dispare involuntariamente. Utility Carburetor Anti-Trigger System, Utility Model patent, refers to a device that prevents involuntary activation, with application in the area of carburetors for two or four-stroke combustion engines, aiming to interrupt the operation of the engine, in case, by any reason, the engine will involuntarily start.
Os carburadores são responsáveis por fazerem a mistura do ar com o combustível e alterarem a rotação do motor a combustão. Dessa forma, quando acionado o acelerador, o carburador libera a passagem do ar e injeta a quantidade de combustível necessária para o aumento da rotação e também a força do motor. Carburetors are responsible for mixing air with fuel and altering the combustion engine speed. In this way, when the accelerator is activated, the carburetor releases air and injects the amount of fuel necessary to increase the speed and also the engine power.
Atualmente os Para motores (aeronave constituída por um Parapente e um motor com uma hélice) utilizam motores a combustão onde necessitam do carburador para o funcionamento do motor. Currently the For engines (aircraft consisting of a Paraglider and an engine with a propeller) use combustion engines where they need the carburetor to run the engine.
É sabido que Inúmeros acidentes foram registrados com pilotos durante o acionamento do motor do Paramotor, onde o cabo do acelerador se encontrava acionado involuntariamente devido a sujeira, ferrugem, ou mesmo por quebra da mola que volta a haste de acionamento do carburador, causando assim o disparo do motor e imediatamente o aumento da rotação da hélice, na qual, a força exercida pela propulsão, acaba empurrando o motor em direção do piloto e o mesmo não consegue segurar o conjunto, sendo atingido pela hélice e sofrendo graves lesões em seu corpo. It is known that innumerable accidents were registered with pilots during the activation of the Paramotor engine, where the throttle cable was activated involuntarily due to dirt, rust, or even due to the break of the spring that returns the carburetor's driving rod, thus causing engine start and immediately increase the propeller rotation, in which, the force exerted by the propulsion, ends up pushing the engine towards the pilot and the pilot cannot hold the assembly, being hit by the propeller and suffering serious injuries to his body.
Com o intuito de solucionar tais problemas desenvolveu-se o Sistema Anti Disparo de Carburador. Sua função é impedir que o carburador seja acionado involuntariamente e consequentemente impeça que o motor aumente a rotação, desligando imediatamente o motor em caso de aumento de rotação involuntária. In order to solve such problems, the Anti Carburetor Trigger System was developed. Its function is to prevent the carburetor from being started unintentionally and consequently to prevent the engine from increasing the speed, immediately turning off the engine in case of an increase in unintended speed.
O sistema é parafusado no carburador e conectado ao aterramento da bobina por meio de cabos.
Quando o sistema é acionado pelo interruptor(6), em caso de aceleração, a haste do sensor(2) que fica próxima á haste de acionamento do carburador(4), são tocadas, fechando o circuito e impedindo que a centelha seja enviada da bobina para a vela de ignição, interrompendo o funcionamento do motor. The system is screwed to the carburetor and connected to the coil ground using cables. When the system is activated by the switch (6), in case of acceleration, the sensor rod (2) which is close to the carburetor actuation rod (4), are touched, closing the circuit and preventing the spark from being sent from the coil for the spark plug, interrupting the engine operation.
A invenção poderá ser melhor compreendida através da seguinte descrição detalhada, em consonância com as figuras em anexo. The invention can be better understood through the following detailed description, in line with the attached figures.
A FIGURA 1 representa uma vista do topo do sensor. FIGURE 1 represents a view from the top of the sensor.
A FIGURA 2 representa uma vista inferior do sensor, mostrando a fu ração para encaixe no carburador. FIGURE 2 represents a bottom view of the sensor, showing the function to fit the carburetor.
A FIGURA 3 representa o condicionamento do sensor no carburador. FIGURE 3 represents the conditioning of the sensor in the carburetor.
A FIGURA 4 representa o acionamento da haste do carburador(õ) por meio do cabo de aceleração, onde a haste do carburador(4) toca na haste do sensor do sistema(2). FIGURE 4 represents the activation of the carburetor rod (õ) through the acceleration cable, where the carburetor rod (4) touches the rod of the system sensor (2).
