ABSTRACT:
A pump unit includes a reservoir for containing a liquid, a duct system for conveying the liquid, and a pumping section for subjecting the liquid to a pumping force. The initial filling of at least a portion of a duct for conveying the liquid from the reservoir to the pumping section is brought about under the influence of another force other than the pumping force, for example, under the influence of gravity.
