Patent #6418751




A accumulator dehydrator assembly containing a straight
trumpet tube as opposed to a “J” tube.
干燥储液器包含一条直喇叭口管，而不
是一个“J”管
The straight tube does not permit the filing with refrigerant
during the compressor off cycle. Therefore, there is no liquid
column to accelerate rapidly and boil off violently. This
reaction causes high energy to be imparted to the A/D which
manifests itself as a broad frequency noise known as
“bump”.
在压缩机关闭循环时，直管内没有制冷
剂。因此，没有液柱加速和剧烈沸腾的
可能性。这种反应会导致高能量迁移到
A / D，导致宽频率噪声。
The straight line trumpet utilizes the venturi effect of a
contracting/expanding cross section to provide liquid oil
pickup to feed to the compressor.
直线喇叭口利用文丘里效应，缩小/扩
大截面提供吸力使润滑油进入压缩机。
This effect also provides the anti-siphon feature (PEH)
这种效应还提供了防虹吸功能（PEH）
