摘要

The pump consists of a seat (12) with an outlet nozzle (20) and two connectors with internal and external threads for barrels (14) with folding handles (19). The connectors are made to take differentsized barrels, e.g. for a child's or adult's bicycle. With the nozzle connected to the tyre valve, air can be pumped from both sides at the same time.
