摘要

The two storage containers (1,2) are mounted in a housing (3) under a pump housing (9), in which the two pumps (5,6) are mounted side-by-side. Each pump has a folded bag or bellows (12) and has an inlet valve (10) at the bottom and an outlet valve (11) at the top. The two pumps are operated by a single actuating member (7) which may be pushed down by a rocker lever (40) mounted in a housing (30) over the pumps.
