Fuel dosing pump for heater in motor vehicle is encased in capsule made at least partially of sound attenuating and heat conducting material

摘要

The fuel dosing pump(2) is encased in a capsule(3) made at least partially of sound attenuating and heat conducting material. The capsule has separate heat transfer elements on the outside and/or heat transfer areas which are especially fins or bumps. The capsule may be constructed in two detachable or hinged halves or in one piece from a material which is easily destructible by a tool. The capsule is formed completely or partially by embedding the fuel pump in a hardening gel, silicon or plastic foam, for example.
