CONSTITUTION: A liquid filter(1), in particular an oil filter comprises a filter housing(2), a no-load duct(5), a pin, and an incline(8). The filter housing comprises a housing space for a ring filter element. A no-load duct opens when the ring filter element is being ejected. A pin is parallelly protruded in the longitudinal direction with an eccentric state and is integrally composed in the bottom end of a disc of the ring filter element. The incline is formed at the bottom of the housing space. The pin slides from the top of the incline to the bottom of the incline when the ring filter element is inserted into the housing. The incline is assembled to the pin to penetrate the opening of the no-load duct. |
