That part is called the thermovalve. It is used to assist in cold starts by making the WUR enrichen the mixture as if it were in full throttle enrichment mode. It is used on K-basic systems only (non-lambda).
The part should be closed when cold starting, and then open up when warmed by its internal heater.
