Title
(EN) Water separator with a water overflow secured by means of a float valve
(ZH) 借助于浮阀的带溢水保护功能的水分离器
Abstract
(EN)
The invention relates to a water separator (10), in particular in the form of a fuel filter for a motor vehicle. The water separator (10) has a water collection chamber (30). The water collection chamber (30) is closed with an overflow valve (38) with respect to a discharge through-cutout (34). The overflow valve (38) has a float (44) which is lighter than water but heavier than fuel, in particular heavier than diesel fuel. The float (44) floats up when water backs up in the water collection chamber (30) and frees the discharge through-cutout (34) that is fluidically connected to the overflow valve (38), via which cutout the backed-up water can flow away. By contrast, fuel does not open the overflow valve (38), such that discharge from the water separator (10) via the discharge through-cutout (34) takes place only in the event of water backing up, and as a result the efficiency of the water separator (10) is greatly increased. The discharge through-cutout (34) is preferably fluidically connected to a fuel tank of the motor vehicle. For regular water removal from the water collection chamber (30), this fuel tank is preferably connected to a water removal device.

本发明涉及水分离器(10),特别地呈用于机动车辆的燃料滤清器的形式。水分离器(10)具有集水室(30)。集水室(30)相对于排水贯通开口(34)由溢流阀(38)关闭。溢流阀(38)具有浮子(44),该浮子轻于水但是重于燃料,特别地重于柴油燃料。随着集水室(30)中的水积聚,浮子(44)上升并打开与溢流阀(38)流体连接的排水贯通开口(34),且使得能经由其来排水。相反的,燃料不会打开溢流阀(38),使得仅在水积聚的情况下才经由排水贯通开口(34)实现从水分离器(10)中的排水,且因此极大提高了水分离器的效率。优选排水贯通开口(34)与机动车辆的燃料箱流体连接。为从集水室(30)定期进行排水,优选此燃料箱与水排放装置连接。
