| 20090236073 | Liquid Filter Heat Exchanger Unit - A liquid filter heat exchanger unit has a heat exchanger having an inlet through which a liquid is supplied to the heat exchanger and a drain through which the liquid exits after having passed through the heat exchanger. The unit also has a liquid filter with a filter housing and a filter element exchangeably arranged in a receiving chamber, wherein the liquid is supplied through the drain of the heat exchanger to an unfiltered side of the filter element. A bypass connects an inlet passage for supplying the liquid to be filtered to the receiving chamber in the filter housing. A switching member opens and closes the bypass. The switching member is formed by the filter element such that the bypass is closed when the filter element is inserted in the filter housing and is opened when the filter element is removed from the filter housing. | 09-24-2009 |
