OIL CLEANING FILTER

摘要

The invention relates to the car industry, more specifically to the structural design of oil filtering devices for internal combustion engines. The inventive filter consists of a cylindrical body provided with a lid, and of a main filtering element provided with bypass and drain valves, a bypass oil filtering element and a pressure-release valve which are coaxially arranged in said body. Said filter also comprises three coaxially arranged springs. One of springs is disposed between the bottom of the body and the bypass valve, the second spring in the bypass valve and the third spring is used for actuating the pressure-release valve in the case of the clogging of an additional filtering element. Said filter is provided with two protection screens. The first screen is coaxially spaced with respect to the side surface of the main filtering element, the second screen being spaced with respect to the side surface of the additional bypass oil filtering element and disposed between the bypass filter and the operating surface of said bypass oil filtering element. Each protection screen is provided with a through hole for the oil input.
