The present invention relates to a filter element using a plastic cap integrated with a relief valve, wherein a net type core 21 is received in a spin-on filter housing 10 in the cylindrical shape opened at the top portion thereof and formed with a plurality of oil passing holes 21 a in the periphery thereof, and an oil pleated paper 22 is positioned to maintain the shape thereof at the periphery of the core 21 so as to be positioned at a small distance from the inner wall of the housing 10. The filter element 20 includes: an upper cap 23 formed of a plastic material at the upper end thereof; and a fixed lower cap 50 integrated with a relief valve formed of plastic material at the lower end thereof. The fixed lower cap 50 integrated with a relief valve receives and fixes a relief valve 30, which is formed of a valve plate 32 and an elastic spring 33. In the filter element 20, the core 21 is covered by the upper cap 23 and the lower cap 50, which are kept in close contact with the outside of the core 21. According to the present invention, assembly of the valve plate 32 and the elastic spring 33 of the relief valve 30 is simplified by integrating a plurality of upper holding protrusions 52 of the fixed lower cap 50 integrated with a relief valve. In addition, the deviation of an element compression spring 25 closely contacting the lower inner surface of the housing 10 by the oil which is introduced into an oil hole 53 is prevented by the integration of the lower holding protrusions 52. Furthermore, the upper cap 23, the fixed lower cap 50 integrated with a relief valve and the core 21 are manufactured by plastic injection molds so as to reduce weight. The spin-on filter may be reused without separation from the oil pleated paper 22, which is fixed by a thermosetting resin 22 a (since both are formed of the same materials) when discarding the spin-on filter. In addition, it is possible to use the element in the generation of renewable energy.

A replacement filter element having a removable pin attached to the filter element is described. The removable pin is attached to the filter element via a first interference fit. When the replacement filter element is installed into a filtration system having a drain valve with an internal draft, the removable pin seals onto the drain valve and forms a second interference fit between the drain valve and the pin. The pin seals an opening in the drain valve. The second interference fit is stronger than the first interference. Accordingly, when the replacement filter element is removed from the filter housing (e.g., during a service event of the replacement filter element), the pin detaches from the replacement filter element and remains positioned within the drain valve thereby preventing fluid from leaking from the housing when the filter element is removed.

A replacement filter element having a removable pin attached to the filter element is described. The removable pin is attached to the filter element via a first interference fit. When the replacement filter element is installed into a filtration system having a drain valve with an internal draft, the removable pin seals onto the drain valve and forms a second interference fit between the drain valve and the pin. The pin seals an opening in the drain valve. The second interference fit is stronger than the first interference. Accordingly, when the replacement filter element is removed from the filter housing (e.g., during a service event of the replacement filter element), the pin detaches from the replacement filter element and remains positioned within the drain valve thereby preventing fluid from leaking from the housing when the filter element is removed. The pin permanently plugs the drain valve once installed. 115-. (canceled)16.
