摘要:<p>The device (10) has a sleeve (3) movably arranged in a front housing part (7) and pressed into a movable plate (4) and a filter insert (5). A funnel surface (3.2) is formed at a side associated to the filter insert. A sealing ring (2) is arranged between the sleeve and a safety ring (1). The sealing ring has a chamfer conical surface (2.1) and a front surface (2.2) that is aligned perpendicular to a flow direction. A pressure absorption section (3.1) is formed in the sleeve within a thin opening width of the sealing ring and is projected into a flow channel (8).</p>
