Joint design of metal and plastic precision parts for FUEL AND CAR ENGINE COOLING

摘要

The invention relates to the field of engine, particularly to a fuel supply system and cooling vehicle engines. Due to the wide spread of plastics for the manufacture of body parts of fuel supply and cooling systems, a great importance is the construction of compounds of metals and plastics body parts, which provides reliable sealing compound. The purpose of this utility model is to reduce the workmanship and reliable sealing connection is maintained throughout the life of the product. This object is achieved in that the compound is sealed by a resilient sealing element which is mounted on the metal part before casting plastic, wherein the plastic material melting temperature must not exceed the melting temperature of the material of the elastic sealing member.
