DEVICE FOR PREVENTING LEAKAGE OF OIL FILTER

摘要

PURPOSE: A device for preventing the leakage of an oil filter is provided to prevent the leakage of oil caused by the transformation of an element in the oil filter and the rise in the position of the element. CONSTITUTION: A core(42) and a relief valve(36) are formed at the center of a housing divided into the upper and lower parts. An element(20) is contained in the space between the housing and the core. The upper end of the element is supported by the inner surface of the upper housing(32), and the lower end of the element is supported by a protrusion formed at the lower side of the core. A support spring is installed at the upper end of the core to prevent an oil inlet(40) from being opened when the element shrinks in length direction. A stopper(37a) is formed at the periphery of a mounting part(37) in the upper housing, and supports the upper end of the support spring.
