Abstract
A filter for squeezing or pressing out suspensions has the following main components: a boiler-shaped outer casing, a cover closing the outer casing at its open end, a tubular filter element projecting from the cover and a membrane which is arranged between outer casing and filter element and connected on the one hand to the open end of the outer casing and, on the other, to the end face of the filter element remote from the cover such that the membrane is inverted when the cover is removed coaxially from the outer casing. In a filter of this type, the membrane and the filter element are pivotable or rotatable as a unit about their common axis when the outer casing is in its closed state.
