摘要

This report gives the details of a foot cum hand pump which has been developed. The existing foot pump (commercially available) can be operated by foot alone, which may not be convenient to all and also needs higher energy input. Modification has been made in the existing foot pump so as to enable it to be operated by hand also instead of by foot alone.
