Description

发动机的化油器座
技术领域 本发明涉及一种发动机， 尤其涉及一种发动机的化油器座。 背景技术 说 目前， 如同以草木为对象的手提式割草机（剪切机）和背负式作 业机， 传统的二冲程和四冲程小型通用发动机， 作为驱动作业人员自 己手提或者背负着进行作业的作业机的发动机， 已经被广泛使用。
书
发动机通常包括气缸和设置在气缸一侧的化油器，在化油器与气 缸之间设有化油器座。在化油器座上设置进气通道， 以便液态的油经 过化油器的汽化后进入到气缸内。 此外， 在化油器上还设置脉动孔， 活塞往复运动产生的负压通过脉动孔传递进入化油器内，使化油器运 转， 而在化油器座上设置有脉动孔通道， 该脉动孔通道连接在化油器 座上的进气通道与脉动孔之间，以将该进气通道内的负压动力引入到 脉动孔内。然而， 现有的脉动孔通道是直接与化油器座上的进气通道 相连接， 这样， 在冷机的时候， 进气通道内的油气很容易液化成液体 而阻塞， 使得化油器不能稳定运转。 发明内容 本发明的目的在于针对现有技术中的上述缺陷，提供一种改进的 发动机的化油器座，其可以防止冷凝的燃油在其脉动孔通道内的堵塞。 为实现上述发明目的， 本发明采用了如下主要技术方案： 一种发 动机的化油器座， 设有轴向通孔和脉动孔通道， 其特征在于： 所述化 油器座还设有防堵件，所述防堵件安装在所述轴向通孔内并设有进气 通道， 所述进气通道与所述脉动孔通道相连通。
此外， 本发明还提出如下附属技术方案：
所述防堵件在其外壁上开设环形凹槽，所述环形凹槽与所述脉动 孔通道相通。
所述环形凹槽上设有通孔。
所述通孔位于所述进气通道的上方。
所述发动机设有气缸和化油器， 所述化油器座设置在所述气缸与 所述化油器之间。
所述发动机的化油器座设有第一端部和相对于第一端部的第二端 部， 所述第一端部与所述气缸相配接， 所述第二端部与所述化油器相 配接。
所述防堵件为一管状物， 其与所述轴向通孔相紧密配合。
相比于现有技术， 本发明的优点在于： 本发明通过在发动机的化 油器座上安装有防堵件， 且该防堵件设有进气通道， 所述进气通道与 所述脉动孔通道相连通，这样以免冷凝的燃油在其脉动孔通道内的堵 塞。
附图说明
图 1是对应于本发明较佳实施例的发动机的剖视图。
图 2是图 1中发动机的化油器座的装配立体图。
图 3是图 2中化油器座的部分立体图。
图 4是图 2中化油器座的防堵件的立体图。 具体实施方式
以下结合较佳实施例及其附图对本发明技术方案作进一歩非限 制性的详细说明。
参照图 1， 对应于本发明较佳实施例的发动机， 为四冲程汽油发 动机， 其包括气缸 1、 化油器 3以及设置在气缸 1与化油器 3之间的 化油器座 5。 其中， 化油器座 5包括第一端部 50和相对于第一端部 50的第二端部 52， 所述第一端部 50与气缸 1相配接， 而第二端部 52与所述化油器 3相配接。
进一歩参照图 2至图 4， 上述化油器座 5设有轴向通孔 54、脉动 孔通道 56和防堵件 60。 该脉动孔通道 56开设在轴向通孔 54的内壁 51上并设有防堵缺口 58。 该防堵缺口 58与化油器 3的脉动孔 32相 连通。
上述防堵件 60， 安装在所述轴向通孔 54内并设有进气通道 53， 所述进气通道 53可与所述脉动孔通道 56相连通。 该防堵件 60为一 管状物， 其与所述轴向通孔 54相紧密配合。 在防堵件 60的外壁 55 上开设环形凹槽 57， 并且在环形凹槽 57上设有通孔 59。 当防堵件 60安装至轴向通孔 54内时，该通孔 59位于所述进气通道 53的上方。 所述环形凹槽 57使得在制造装配时更加方便， 同时在制造时， 可根 据机器的不同使用情况， 调整通孔 59的位置， 使其处于进气通道 53 上方， 防止通孔 59被堵塞。
这样， 本发明通过上述通孔 59将进气通道 53与脉动孔通道 56 相连通， 并且通过将通孔 59设置在进气通道 53的上方， 使得经过化 油器 3汽化后的燃气会顺利的通过进气通道 53而进入气缸 1内， 减 少甚至避免了冷凝的燃油将脉动孔通道 56或脉动孔 32堵塞。本发明 所提供的发动机的化油器座 5， 其结构新颖、 运行效果良好， 对发动 机的稳定工作有很好的效果。
需要指出的是，上述较佳实施例仅为说明本发明的技术构思及特 点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以 实施， 并不能以此限制本发明的保护范围。凡根据本发明精神实质所 作的等效变化或修饰， 都应涵盖在本发明的保护范围之内。
