Abstract
SISTEMA DE REFRIGERAçãO PARA MOTOR DE COMBUSTãO INTERNA Um sistema de refrigeração para um motor de combustão interna incluindo uma bomba com um impulsor (10) para bombear refrigerante líquido em torno de um circuito de refrigeração, e um eixo de acionamento (14), em que entre o impulsor (10) e o eixo de acionamento (14) é provida uma embreagem (16) incluindo primeiro elemento de embreagem (18) e segundo elemento de embreagem (20) os quais são móveis para engate e desengate, para conectar e desconectar acionamento do eixo de acionamento (14) ao impulsor (10), respectivamente, por intermédio de um dispositivo de detecção de temperatura (22) o qual inclui uma câmara (24) na qual é provido um material (26) que através de uma primeira faixa inferior de temperaturas está em um primeiro estado, e através de uma segunda faixa superior de temperaturas está em um segundo estado, o material (26) mudando de volume ao passar do primeiro para o segundo estado para induzir o primeiro elemento de embreagem (18) e o segundo elemento de embreagem (20), em conjunto, para transmitir acionamento, e em que o impulsor (10) tem uma parte oca interna (12a) para dentro da qual o refrigerante a ser bombeado pode passar, de modo que o refrigerante esteja em comunicação térmica com o material (26) na câmara (24).INTERNAL COMBUSTION ENGINE COOLING SYSTEM A cooling system for an internal combustion engine including a pump with an impeller (10) for pumping liquid refrigerant around a refrigeration circuit, and a drive shaft (14), wherein Between the impeller (10) and the drive shaft (14) there is provided a clutch (16) including first clutch element (18) and second clutch element (20) which are movable for engagement and disengagement for connecting and disconnecting. actuation of the drive shaft (14) to the impeller (10) respectively by means of a temperature sensing device (22) which includes a chamber (24) in which a material (26) is provided which through a first Lower temperature range is in a first state, and through a second upper temperature range is in a second state, material (26) shifting from first to second state to induce the first first clutch element (18) and second clutch element (20) together for drive transmission, and wherein the impeller (10) has an inner hollow part (12a) into which the refrigerant to be pumped can pass, so that the refrigerant is in thermal communication with the material (26) in the chamber (24).
