Sicherheitsverschluss für einen Wasserbehälter einer Dampfdruck-Kaffeemaschine.

摘要

Safety closure for a water reservoir of a steam pressure coffee machine having of the top of the water reservoir (1) a rather wide hole (2) with a disk-shaped stopper (4), to which is stiffened a rod (6) that projects to the outside and that plays in a guide bush (7), which is mounted coaxially with regard to the hole (2). The stopper (4) tends to be closed, not only because of the reservoir (1) pressure, when present, but also because of a spring (12, 18, 20) that urges the rod (6) upwards, either directly or through an arm (19) or a push-button (21) which must be pressed by hand in order to open the safety closure during the filling operation. This latter being made easier by the provision of a funnel (11), that can but need not be sealed with a cover (22).
