Filter device, in particular fuel filter or oil filter

摘要

A filter device has an annular particle filter having a raw side face and a radially separated clean side face, and axially opposing end faces. An annular water separating element is arranged in a flow path downstream of the particle filter, the water separating element circumferentially surrounding the particle filter at a radial spacing. An open inner annular space is defined by and between the particle filter and the water separating element and an outer annular space is defined by and between the water separating element and the filter housing.

1. A filter device for filtering a fluid, the filter device comprising:
an annular particle filter elongated in the direction of a central axis and circumferentially enclosing the central axis; wherein axial is a direction parallel to the central axis; wherein radial is a direction transverse to the central axis; wherein the annular particle filter has a raw side face where fluid enters the annular particle filter and a radially separated clean side face where purified fluid exits the particle filter and axially opposing end faces; an annular water separating element arranged in a flow path downstream of the particle filter; wherein the water separating element circumferentially surrounds the particle filter at a radial spacing; wherein an open inner annular space is defined by and between the particle filter and the water separating element; wherein an outer annular space is defined by and between the water separating element and a filter housing; a coalescing element is arranged in the flow path between the particle filter and the water separating element; wherein the coalescing element is arranged on one of the end faces of the particle filter.
