    摘要： A filter head assembly includes a relief valve assembly therein, and is adapted for use in a spin-on filter or the like. When the relief valve assembly is in a closed mode of operation, fluid flow through the filter head, and an associated filter, results in conventional filtration. When the relief valve assembly is in open mode of operation, the filter is substantially bypassed permitting fluid to flow directly through the filter head, with filtration. The relief valve assembly includes a movable piston member therein, which opens and closes for the respective flow passage outwardly from a lateral takeoff port. Any substantial, undesirable, lateral forces acting upon a piston member may be substantially reduced by means of a lateral pressure release system provided according to the present invention. Generally, the lateral pressure-relief system comprises an annular recess formed in the piston member. The preferred piston member is cup-shaped and has an outer sidewall slide portion which forms a slip fit with a valve body relief valve. The preferred slide member includes groove means therein, facilitating movement. Also, preferably, a first end of the piston member includes an annular portion thereon providing an extension of a first end of the piston member to increase surface area against which fluid pressure may act.

    摘要翻译： 过滤器头组件包括其中的安全阀组件，并且适于在旋转过滤器等中使用。 当安全阀组件处于闭合操作模式时，流过过滤嘴的流体和相关过滤器导致常规过滤。 当安全阀组件处于打开操作模式时，过滤器基本上被旁路，允许流体通过过滤直接流过过滤器头。 安全阀组件包括其中的可移动活塞构件，其从侧向起飞端口向外打开和关闭相应的流动通道。 通过根据本发明提供的侧向压力释放系统，可以大幅度地减小作用在活塞构件上的任何实质的，不期望的横向力。 通常，侧向减压系统包括形成在活塞构件中的环形凹部。 优选的活塞构件是杯形的并且具有与阀体安全阀形成滑动配合的外侧壁滑动部分。 优选的滑动构件包括槽装置，便于移动。 此外，优选地，活塞构件的第一端包括其上的环形部分，其提供活塞构件的第一端的延伸部，以增加流体压力可以作用的表面积。

    摘要： The present invention is directed to a duplex filter apparatus which provides for a first primary filter path and a second path for secondary filtration. The first path includes a shutoff valve on one side of the primary filter and a check valve on the downstream side. The second path includes a regulating bypass valve on the upstream side of the secondary filter and a check valve on the downstream side. The regulating bypass valve gradually shifts fluid flow from the first path to the second path when differential pressure across the primary filter increases beyond a predetermined level. A reservoir return bypass valve directs fluid flow gradually from the secondary filter when differential pressure across the secondary filter increases beyond a predetermined level. Bleed valves are provided to relieve pressure on filter elements when the filter elements are isolated so that servicing may occur.

    摘要翻译： 本发明涉及一种双相滤波器装置，其提供第一主滤波器路径和用于二次滤波的第二路径。 第一路径包括主过滤器一侧的截止阀和下游侧的止回阀。 第二路径包括在次级过滤器的上游侧的调节旁通阀和下游侧的止回阀。 当主过滤器上的压差增加超过预定水平时，调节旁路阀逐渐将流体从第一路径流动到第二路径。 当二级过滤器上的压差增加超过预定水平时，储油器回流旁路阀引导流​​体从次级过滤器流出。 提供排气阀以在过滤元件隔离时减轻过滤器元件上的压力，从而可能发生维修。

    摘要： A filter head adapted for use with spin-on filters is shown. The filter head carries a spring load piston which is normally biased to close a filter bypass channel. A fluid pressure increase caused by a clogged filter causes the piston to move opening the bypass and at the same time opening a signal channel between a source of fluid pressure and a signal outlet.
