Abstract
Patente de Invenção: <B>"VáLVULA DE INJEçãO DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO INTERNA"<D>. Uma válvula de injeção de combustível para motores de combustão interna, com um correspondente corpo de válvula (30), sendo que o corpo de válvula (30) é inserido na perfuração de recepção (9, 10) da carcaça (15) e um motor de combustão interna e, por meio de um elemento de aperto (1) que é atarraxado em uma rosca interna (12), configurada na extremidade da perfuração de recepção (9, 10), afastada da câmara de combustão, e um elemento de apoio (2), disposto em uma ranhura anular (4), com um ressalto anular (17), configurado no corpo de válvula (30), é apertado contra uma superfície de encosto (18), configurada na perfuração recepção (9, 10). A superfície lateral interna do elemento de aperto (1) e a superfície lateral externa do elemento de apoio (2) são configuradas conicamente, de modo que, por meio do movimento axial do elemento de aperto (1), por ocasião do atarraxamento, é exercida uma força radial sobre o elemento de apoio (2), com o que ele é pressionado, com sua superfície lateral interna em forma de cilindro, para o interior da ranhura anular (4), e assim, uma elevada força axial pode ser transmitida para o corpo de válvula (30), sem que, neste caso, apareçam elevadas compressões superficiais.
