FILTER FOR LIQUIDS, IN PARTICULAR INTERNAL-COMBUSTION ENGINE LUBRICANT OILS.

摘要

In a liquid filter having a pot-shaped housing having the pot bottom situated underneath, a cover (42) which can be screwed on and at least one exchangeable annular filter insert (46) through which flow passes radially from the outside to the inside, in which by unscrewing the cover (42) on the pot bottom at least one outlet channel (45) which is closed at least in the oil filter out of operation is cleared, a liquid outlet on opening the cover is to be created in the simplest possible manner with respect to construction and function. This is achieved by the means for clearing the oil outlet orifice being a support piece (50) which is axially engaged in a force-transmitting manner with the cover (42) and lies in the liquid filter axis determined by the at least one filter insert (46), the end of which support piece (50) with the cover (42) closed projects into the outlet channel (45) and in this state closes it liquid-tightly and opens it when the cover (42) is open.
