Embodiment Construction
[0034] The same or similar components are provided with the same symbols in different figures. The presentations are schematic and not comprehensive.
[0035] 1A to 1C show a check valve device for an automobile according to an exemplary embodiment of the present invention. The non-return valve has a valve sleeve 1 with an inflow opening 2 and an outflow opening 3 , and a valve element 4 which is displaceably mounted in the valve sleeve 1 . When the valve element 4 is in the first position, a first flow cross section A1 between the outflow opening 3 and the valve element 4 is adjusted ( FIG. 1A ). The outflow connection 3 is closed by the valve element 4 when the valve element 4 is in the second position. Therefore no flow cross section is provided. When the valve element 4 moves in the first movement area B1 and the second movement area B2, the liquid flow cross-section A will change continuously. Wherein, the continuous change of the liquid flow cross-section A in the fi...
