LIQUID FILTER FOR THE LUBRICATING OIL OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
A liquid filter for cleaning the lubricating oil of an internal combustion engine which comprises a vertically upstanding filter housing 10 closed at the top by a removable cover 12. In this filter housing there is a filter insert 18 which is removable for maintenance and separates a dirty liquid chamber 41 from a filtrate chamber 42 in the filter housing. When the cover 12 is opened and the filter insert 18 is removed, the liquid drains out through a drain passagway 17. This drain passageway 17 is provided with a shut-off device 25 which shuts off the drain passageway 17 when the filter insert 18 is installed, and which opens this drain passageway 17 when the filter insert 18 is loosened. The shut-off device 25 is a compact unit which can be mounted and inspected outside the filter housing 10, and can be used for filter housings of various sizes.
