Description

机油滤清器
技术领域
本发明涉及一种滤清器， 特别是涉及一种用于各种 发动机和内燃机的机油滤清器。 背景技术
现有的滤清器有各种结构， 但不外均是包合有一个 外壳， 一个上盖， 以及用于过滤机油的织物滤芯。 同时 还包合有一个压力调整装置， 该压力调整装置为一进油 口可关、 .可开的压力调整阀。 但现有滤清器压力调整阀 具有如下缺点：
1 、 其上的进油口结构设计不合理。 当机油供给压 力出现波动时， 压力调整阀反应不够炅敏， 不但波动必 须达到一定的量值， 并需波动足够的时间后， 压力调整 阀才起作用， 故整个机油系统会因内部压力不能及时调 整而受到损害。
2 、 现有的压力.调整阀，. 尽管能在机油压力发生变 化时打开旁通油路， 伹自其进油口进入的机油因未经织 物滤芯过滤而带有的颗粒极易卡嵌在阀杆与阀体之间而 导致阀杆运动迟滞， 甚至被卡制住的现象而使得整个调 整阀不能正常工作甚至失炅。
有鉴于此， 本发明提出一种其中的压力调整阀对机 油压力反应炅敏， 动作快速炅活的机油滤清器。 发明内容

本发明提出的机油滤清器结构简单， 反应炅敏， 动 作炅活， 十分实用。 附图概述
以下结合附图对本发明予以详细说明；
图 1 是本发明提出的机油滤清器的立体分解示意图; 图 2 是阀管的局部剖视示意图；
图 3 是阀件的局部剖视示意图；
图 4 是阀镙母的局部剖视示意图；

如图 1 、 图 8 和图 9 所示， 本发明提出的机油滤清 器包括有壳体 1 , 在壳体 1 内依次从下到上装有下滤网 8 、 织物滤芯 9 、 上滤网 7 、 密封环 1 1 、 上盖 2 和环 形圈 1 2 ， 上盖 2 的中部具有出口通孔， 环绕出口通孔 具有入口旁孔 2 1 。
由阀管 3 和装于其中的弹赘 1 0 , 阀件 5 和阀螺母 构成的压力调整阀穿设在织物滤芯 9 和上滤网 7 的中 心孔中， 阀管 3 的外壁与织物滤芯 9 中心孔的内壁紧密 配合， 且其上的进油口 3 1 位于织物滤芯 9 的上部而不 被其遮盖。 如图 2 和图 3 所示， 阀管 3 为空心管件， 在 其一端部沿周向开设有进油口 3 1 , 而且与现有滤清器 所不同的是该进油口的内壁是倾'斜的； 阀件 5 为一中空 柱形体， 其与现有滤清器相应部件所不同之处在于， 其 外周缘上形成与其内部相通的镙綻槽 5 2 ， 阀件 5 上的 镙綻槽 5 2 是通过孔 5 3 与阀件 5 内部沟通的。 并且， 与嫘母 4 配合的一端 5 1 上的截面形状为 " 〈" 形。 该 " 〈" 形截面端 5 1 靠近阀件外周面的一段的倾斜角度 与上述阀管 3 的进油口 3 1 的壁的倾斜角度相一氣 其 靠近阀件中心 '的'另一段在阀件的顶端处具有与嫘母 4 的 配合部。 镙母 4 如图 4 所示， 其内部具有中心孔， 且外 周面上具有与阀管 3 配合的.嫘纹， 嫘母 4 与阀件 5 配合 一端处， 外周面直径渐减成截园锥台形， 而中心孔直径 渐扩， 以与阀件 5 的端部 5 1 配合。
如图 5 所示， 本发明提出的滤清器中的压力调整阀

更 正 ^ 组合完成后， 阀嫘母 4 螺装在阀管 3 的一端上， 且其一 端部与可相对滑动地位于阀管 3 内的阀件 5 的端部 5 1 配合构成阀的压力慼应'口， 且该压力惑应口正好与阀管 3 上的进油口 3 1 对准， 弹簧 1 0 装于阀件 5 的另一端。
如图 6 结合图 8 所示， 当机油供给系统供油正常时, 自上盖 2 上的旁孔 2 1 进入的机油经上滤网 7 的初级过 滤后， 进到织物滤芯处进行全面过滤， 经过织物滤芯过 滤的油从织物滤芯 9 的底部经下滤网 8 、 弹簧 1 0 以及 阀件 5 和阀镙母 4 的中心孔而被送出。
当滤芯 9 ·由于某些原因部份堵塞或者滤清器下游发 生要求油量增加的状况时， 流动的油的流迷会下降并且 压力升高如图 7 结合图 9 所示， 自上盖 2 上的旁孔 2 1 进入的机油经阀管 3 的进油口 3 1 而作用在调整阀的压 力慼应口上， 由于油压增大和流动油的动量变化而产生 的力将阀件 5 逆着弹簧 1 0 向下推移， 使阀件 5 与阀螺 母 4 分开， 从而分流部分机油从：阀件 5 与阀嫘母 4 之间 进入阀管 3 而经阀嫘母 4 的中心孔流出。 如图 6 及图 7 所示， 由于本发明阀件 5 的 " 〈" 形截面端部与阀螺母 4 的端部构成的独特构形的压力感应口， 而可利用机油 的微小压力变化及流动油的动量变化而转化的力来驱动 阀件 5 的运动从而使阀件 5 能炅敏地根据油流状况的变 化压迫弹簧 1 0 下移而在其与螺母 4 之间产生一个适当 大小的开口以分流机油 另外， 由于阀件 5 的 " 〈" 形 截面端部 5 1 与阀管 3 相邻段的倾斜角度与进油口 3 1 的内壁的相同， 故部分机油可容易地经由该截面为 " < " 的部分， 从而使阀件 5 以最快速度慼应到流动油的波动。
如图 3 可以看出， 阀件 5 的外周面上具有与内部相 通的嫘旋槽 5 2 , 其作用是： 由压力调整阀分流进入该
