摘要： The invention relates to a refrigeration compressor having a sealed housing defining a suction volume and a compression volume respectively provided on either side of a body (5) contained in the housing, and an oil injection circuit adapted for injecting oil into the compression volume. The oil injection circuit includes a stopper (26) mobile under the action of a centrifugal force between a first position for injecting oil into the compression volume and a second position preventing or limiting the injection of oil into the compression volume, wherein the stopper (26) is adapted so as to move into the second position when the speed of the compressor exceeds a predetermined value.
摘要翻译：本发明涉及一种制冷压缩机，其具有密封壳体，其限定分别设置在容纳在壳体中的主体（5）的任一侧上的吸入容积和压缩体积，以及适于将油注入压缩容积的注油回路。注油回路包括在离心力作用下移动的止动件（26），用于将油注入压缩容积的第一位置和防止或限制将油注入压缩容积的第二位置，其中止动件（26））适于当压缩机的速度超过预定值时移动到第二位置。

摘要： The compressor of the invention includes a sealed housing defining a suction volume and a compression volume respectively provided on either side of a body (5) contained in the housing, an oil injection circuit supplied with oil from an oil contained in a casing (22) and adapted for injecting oil into the compression volume, the oil injection circuit comprising an electrovalve (25) including a body (26) attached to the wall of the sealed housing and a core (34) movable under the action of a magnetic fluid between a closing position for injecting oil into the compression volume and an opening position preventing or limiting the injection of oil into the compression volume. The compressor includes a control means for moving the core (34) of the electrovalve between the opening and closing positions based on the compressor speed and/or on the cooling gas discharge temperature.
摘要翻译：本发明的压缩机包括密封壳体，其限定分别设置在容纳在壳体中的主体（5）的任一侧上的吸入容积和压缩体积，从包含在壳体（22）中的油供给油的注油回路，并且适于将油注入到压缩容积中，所述注油回路包括电阀（25），所述电阀包括安装在所述密封壳体的壁上的主体（26）和在所述密封壳体的磁性流体的作用下可移动的芯体（34）关闭位置，用于将油注入到压缩容积中，以及打开位置，防止或限制将油注入压缩体积。压缩机包括控制装置，用于基于压缩机速度和/或冷却气体排出温度，在打开和关闭位置之间移动电动阀芯（34）。
