PROCEDIMENTO DI FABBRICAZIONE DI UNA POMPA D'INIEZIONE DI COMBUSTIBILE

摘要

A method of manufacturing a fuel injection pump includes the step of broaching a bore in a pump body to accomodate a cylindrical pump barrel. The broached bore is of non-circular section and has at least three flat sides which contact the cylindrical surface of the barrel. In addition the broached bore defines a tongue which locates in a groove in the barrel to prevent rotation of the barrel in the body.
