摘要： A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end and defines a central flow aperture. The baffle plate also defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate and spaced from and circumscribing the continuous groove. A filter assembly including the spin-on filter cartridge and a filter head is also disclosed wherein the filter cartridge is removably mountable on the filter head. When the spin-on filter cartridge is oriented on the filter head, a seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components.

摘要翻译： 旋转式滤芯包括壳体，可操作地定向在壳体中的过滤元件，挡板和密封装置。 挡板可操作地定位在壳体开口端上并限定中心流动孔。 挡板还限定了紧邻中心流动孔的连续槽。 密封装置被固定到挡板上，与连续凹槽间隔开并限制。 还公开了一种包括旋转过滤器滤芯和过滤头的过滤器组件，其中过滤器滤芯可拆卸地安装在过滤器头部上。 当旋涂过滤器滤芯定位在过滤器头上时，密封件被容纳在连续槽内，并且密封装置在挡板和过滤头之间形成密封。 密封件可以是径向的或轴向的或具有轴向和径向部件。
