具有过滤器旁通阀的过滤器以及用于所述过滤器的滤芯
Abstract:
本发明涉及一种过滤器（1），该过滤器具有过滤器壳体（2）、用于有待过滤的液体的入口（11）和用于经过过滤的液体的出口（12）、将所述过滤器（1）的未处理侧（13）与净化侧（14）彼此分开的、能够更换的滤芯（3）以及过滤器旁通阀（5），所述过滤器旁通阀包括阀座（50）和在能够相对于所述阀座（50）运动的情况下得到导引的、朝关闭方向被预加负荷的阀体（51）。所述按本发明的过滤器（1）的特征在于，所述阀座（5）以固定在过滤器上的方式布置在所述过滤器（1）中，所述阀体（51）在固定在过滤器上的情况下在所述过滤器（1）中得到了导引，朝关闭方向向所述阀体（51）预加负荷的弹簧（52）在固定在过滤器上的情况下在所述过滤器（1）中得到了导引，并且所述滤芯（3）具有在其被安装到所述过滤器壳体（2）中的状态中在所述弹簧（52）的背向所述阀体（51）的端部处对所述弹簧（52）进行支撑的并且将其预紧的弹簧支柱（53）。此外，本发明涉及一种与所述过滤器（1）共同作用的滤芯（3）。
Abstract(English):

The invention relates to a filter (1), comprising a filter housing (2), an inlet (11) for liquid to be filtered, an outlet (12) for filtered liquid, an exchangeable filter insert (3), which separates an unfiltered side (13) and a filtered side (14) of the filter (1) from each other, and a filter bypass valve (5), which consists of a valve seat (50) and a valve body (51), which is guided in such a way that the valve body can be moved in relation to the valve seat and which is preloaded in a closing direction. According to the invention, the filter (1) is characterized in that the valve seat (50) is arranged in the filter (1) in such a way that the valve seat is fixed to the filter, that the valve body (51) is guided in the filter (1) in such a way that the valve body is fixed to the filter, that a spring (52) that preloads the valve body (51) in the closing direction is guided in the filter (1) in such a way that the spring is fixed to the filter, and that the filter insert (3) has a spring support (53), which, when the spring support is installed in the filter housing (2), supports and prestresses the spring (52) at an end of the spring facing away from the valve body (51). The invention further relates to a filter insert (3) that interacts with the filter (1).
