Abstract
A ceramic valve unit for a beverage machine including a housing, a water inlet pipe for receiving hot water, an outflow opening, and first and second ceramic elements within the housing. The first and second ceramic elements each have mutually abutting surfaces and are relatively movable in a plane common to the abutting surfaces. The plane common to the abutting surfaces is downstream of the water inlet pipe and the first ceramic element, but upstream of the second ceramic element and the outflow opening. The first ceramic element has at least differently sized first and second openings for allowing a liquid flow there through. The second ceramic element has only a single liquid flow opening permanently aligned with the outflow opening. The first ceramic element is selectively slidable between at least first and second different positions preferably in a path of movement about a centre of rotation beyond the boundaries of the first ceramic element.
