Check valve for use in internal combustion engine of motor vehicle, has spring element pre-stressing closing body into end position, where closing body is pre-stressed in end position by magnetic attraction between elements

摘要

The check valve has a housing (10) with a through channel (20) connecting an inlet opening (12) and an outlet opening (16). A closing body (22) is movable between a pair of end positions. A spring element (30) pre-stresses the closing body into one end position. An element (36) is movable with the closing body, and another element (38) is at a fixed position. One of the elements is a magnetic element and the closing body is pre-stressed in the end position by the magnetic attraction between the elements.
