Filter device, especially for filtering liquids in internal combustion engines
摘要：
A filter device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A liquid to be filtered is introduced into the filter housing and flows through the filter element. An overflow valve is arranged between an entry side and a clean side of the filter element and has a valve body. The overflow valve is in an open position when a pressure of the liquid at the entry side of the filter element exceeds a threshold value. The valve body of the overflow valve is a sealing hose placed between the entry side and the clean side onto a cylindrical supporting body arranged in the filter housing. Flow openings are provided in the cylindrical supporting body. The sealing hose is arranged at the clean side of the supporting body.
摘要（中）：

用于过滤内燃机中的液体的过滤装置具有过滤器壳体和插入过滤器壳体中的过滤元件。 要过滤的液体被引入过滤器壳体并流过过滤元件。 溢流阀布置在过滤元件的进入侧和清洁侧之间，并具有阀体。 当过滤元件入口侧的液体的压力超过阈值时，溢流阀处于打开位置。 溢流阀的阀体是将入口侧和清洁侧之间的密封软管放置在布置在过滤器壳体中的圆柱形支撑体上。 在圆筒形支撑体中设有流动开口。 密封软管布置在支撑体的清洁侧。
