摘要： A relief valve for an oil filter device integrally formed with a check valve has an annular shape, and has a front end portion, a guiding portion, a sealing portion, a recess portion, and a groove portion. The relief valve is attached to a protector only by inserting a cylindrical protector end portion into the groove portion thereof. At this time, the recess portion is elastically deformed so that the sealing portion moves inwardly, while the sealing portion is elastically compressed by the protector end portion. As a result, the relief valve closes an oil flow passage defined in a wall of the protector end portion only by an elastic deformation stress thereof. The relief valve can be readily molded and attached to the oil filter device and stably provide desired valve opening characteristics.

摘要： A filter element has a generally ring-like structure which basically comprises a plurality of generally radial sections circumferentially arranged to define a central space. Each radial section has a plurality of circumferentially zigzag pleats formed from a ribbon of a filtering sheet material. The radial sections are circumferentially connected such that radially inwardly open generally radial spaces and radially outwardly open generally radial spaces are defined. The radially inwardly open radial spaces are closed at the axially opposite ends by end walls. Fluid to be filtrated can enter the radially outwardly open radial spaces and then passes through the zigzag pleats into the radially inwardly open radial spaces and thus into the central space. The ring-like structure has many modifications.

摘要翻译： 过滤器元件具有大致环形结构，其基本上包括周向布置以限定中心空间的多个大致径向部分。 每个径向部分具有由过滤片材料的带形成的多个周向Z字形褶皱。 径向部分周向连接，使得径向向内敞开的大致径向空间和径向向外敞开的大致径向空间被限定。 径向向内开放的径向空间在轴向相对端处由端壁封闭。 要过滤的流体可以进入径向向外开放的径向空间，然后通过Z形折叠进入径向向内敞开的径向空间，从而进入中心空间。 环形结构有许多修改。
