Title: FILTER DEVICE
Abstract:
The invention relates to a filter device comprising a pot-shaped filter housing (1) that defines a longitudinal axis along which a filter element (13) can be inserted into and removed from the filter housing (1). A retaining device detachably retains the filter element (13) in the filter housing (1) and comprises first and second retaining elements that are provided on the inner side of the filter housing (1) and on the filter element (13) and that interact with one another. At least one set of the retaining elements has a shape coaxial to the longitudinal axis of the filter housing (1) and forms at least a part of a thread in such a manner that, when the filter element (13) is rotated about its longitudinal axis, it is locked in a form-fit.
