Abstract

"DISPOSITIVO DE DESCOMPRESSãO DE MOTOR DE COMBUSTãO INTERNA DE CICLO DE QUATRO TEMPOS". A presente invenção refere-se a um dispositivo de descompressão de um motor de combustão interna de ciclo de quatro tempos (1) possuindo válvulas de admissão e exaustão (9, 10) aberta e fechada pelos cames de admissão e exaustão respectivos (27, 28) feitos integral com um eixo de came (13) compreende um came de descompressão (38) encaixado no eixo de came (13) de modo a rodar livremente, uma embreagem de um sentido (29) encaixada no eixo de came (13) capaz de transmitir torque de rotação reversa para o came de descompressão (38) quando o eixo de came (13) roda em reverso, um limitador de torque (40) inserido entre o came de descompressão (38) e a embreagem de um sentido (29), e dispositivo de parada de came de descompressão (42, 43) fornecidos em uma parte fixa engatando com uma seção de engate (41) formada no came de descompressão (38) para parar a rotação do came de descompressão (38) em posições respectivas em direção rotacional normal e em direção rotacional reversa. A elevação de uma seção de came (38a) do came de descompressão (38) sendo maior que um círculo base do came de exaustão (28) e menor que uma elevação máxima de uma seção de came (28a) do came de exaustão (28). A válvula de exaustão não sendo aberta pelo came de descompressão quando o eixo de came (13) roda normalmente e o dispositivo de parada de came de descompressão (43) engata com a seção de engate. Um dispositivo de descompressão que é simples em construção, de pequenas dimensões e de baixo custo é fornecido.
