Abstract

A hand pump suitable for inflating rubber dinghies or pneumatic mattresses has a cylinder (c) with a piston (C). The base of the pump is formed by a cast block which contains two non-return valves, (19, 23). When used as an inflator, air is drawn in through the inlet (11) which is open to the atmosphere, and delivered to the mattress or dinghy through the outlet (10) and pipe (R). The pump can also be used to create a vacuum by connecting the inlet (11) to the vessel being evacuated and the outlet (10) to the atmosphere.
