FUEL INJECTOR

摘要

An electrical module for use within a fuel injector for delivering fuel to an internal combustion engine is described. The electrical module has a variable length. The electrical module comprises electrical contacts for operatively connecting the electrical module to a power plug of a fuel injector. The electrical module also comprises an actuator for operatively controlling a control valve disposed within the fuel injector. The electrical module also comprises electrical conductors arranged within a protective housing. These electrical conductors provide an electrical connection between the electrical contacts and the actuator in order to provide electrical power to the actuator when the electrical contacts are operatively connected to the power plug of the fuel injector. The body of the electrical module is comprised of a compressible elastic element, such that the length of the module is variable by compressing the elastic element. Injectors including such electrical modules are also described.
