A filter comprising a housing, which consists of at least two housing parts, and a filter element attached inside the housing. The invention provides for at least one latch element by means of which a detachable latched connection can be established between the filter element and at least one of the housing parts.

Filter

A liquid filter includes an openable filter housing. The liquid filter has an unfiltered-liquid inlet and a clean-liquid outlet. A first filter element is arranged in the filter housing. The first filter element has an essentially hollow-cylindrical design, with the liquid flow travelling through it from the outside to the inside. An additional hollow-cylindrical filter element is arranged inside of the first filter element, wherein the liquid flow is also from the outside to the inside through the additional filter element. A separating wall is disposed between the two filter elements. The entire filter has a compact construction with a large effective filter area.

Liquid filter

An oil separator for the gases of the crankcase ventilating system of an internal-combustion engine has a filter element through which the breathing gases flow and from which the separated oil is returned via an oil return into the oil tank 4. The blow-by gases, from which the oil was removed, are supplied to the air intake system of the internal-combustion engine. A vacuum generator is provided which generates a specified constant vacuum for the sucking-off of the blow-by gases. In addition, an air oil removal element that separates the oil has microfibers which are made of fiber glass material.
