A liquid inlet passage and a liquid outlet passage are provided at the housing. A replaceable, substantially hollow cylindrical filter insert is vertically arranged in the housing. The filter insert being formed of a filter material member arranged between an upper and a lower disc. A collar, which is impervious to solid contaminants removed by the filter material member, extends from the lower disc upwardly along a part of the height of the filter insert, surrounding an outer circumference of the filter insert member. In this manner a collection chamber is formed for the filtered solid particles at the lower disc.
