具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至图6所示，本发明的实施例提供了一种间隔件，间隔件用于设置在第一气缸与第二气缸之间，间隔件包括本体10、通孔20和导油腔30。其中，本体10具有相对设置的第一端面和第二端面，第一端面和第二端面分别用于与第一气缸和第二气缸配合连接。通孔20设置在本体10上，通孔20用于穿设曲轴。导油腔30设置在本体10上，导油腔30与通孔20连通。
应用本实施例的技术方案，在间隔件的本体10上设置导油腔30，并将导油腔30与本体10上的通孔20连通，这样压缩机在工作时，曲轴与通孔20之间的润滑油能够流动到导油腔30内，导油腔30内温度相对较低的润滑油通过热传导可对第一气缸或第二气缸内的冷媒进行冷却，从而能够降低冷媒的温度，提高压缩机的能效。
具体地，导油腔30设置在本体10的靠近第一气缸的吸气孔和/或靠近第二气缸的吸气孔的位置。气缸在工作时在吸气孔的位置以及靠近吸气孔的吸气腔内产生吸气过热的问题。通过将导油腔30设置在本体10的靠近第一气缸的吸气孔或靠近第二气缸的吸气孔的位置，可以通过润滑油的冷却作用防止吸气过热。这样可以降低冷媒的温度，从而提高压缩机的容积效率和能效。将导油腔30设置在同时靠近第一气缸的吸气孔和第二气缸的吸气孔的位置，可以同时防止两个气缸吸气过热。
如图1所示，导油腔30为扇形结构。将导油腔30设置为扇形结构，可以增大导油腔30的体积，以使导油腔30内存储更多的润滑油，并且可以与气缸的吸气区域的形状相匹配，从而可以提高对冷媒的冷却效果。本实施例中的润滑油可以理解为压缩机中的冷冻油。在本实施例中，可以将扇形结构的两个端面之间的夹角设置为180°至220°，以与气缸的吸气区域相匹配。
在本实施例中，导油腔30的入口与通孔20连通，导油腔30的出口与本体10的外部连通。如此设置可使润滑油在导油腔30内流动，从而加强换热作用，提高对冷媒以及第一气缸或第二气缸的冷却效果。
如图2所示，间隔件还包括第一通道40，第一通道40设置在本体10上，导油腔30通过第一通道40与通孔20连通。通过设置第一通道40，可便于对润滑油进行引导，以使润滑油顺畅地流入导油腔30。
第一通道40可以与本体10的外部连通，也可以不与本体10的外部连通。在本实施例中，第一通道40包括第一入口41、第一出口42和第二出口43。其中，第一入口41与通孔20连通，第一出口42位于本体10的外侧面，第二出口43位于第一入口41与第一出口42之间，导油腔30与第二出口43连通。如此设置可使进入第一通道40的润滑油既可以流入到导油腔30内，又可以流出到本体10的外部，从而可以加强润滑油的流动，提高换热效果。
如图1所示，导油腔30与第一通道40间隔设置在本体10上，间隔件还包括第二通道50，第二通道50设置在本体10上，第二通道50的出口与导油腔30连通，第二通道50的入口与第一通道40连通。通过设置第二通道50，可以对进入第一通道40的润滑油进行分流，使一部分润滑油进入导油腔30，另一部分润滑油流出到本体10的外部或其他位置。
如图2所示，间隔件还包括第三通道60，第三通道60设置在本体10上，第三通道60的入口与第一通道40连通，第三通道60的出口位于第一端面和/或第二端面上，第三通道60的出口用于与气缸的滑片槽连通。通过设置第三通道60，可以将间隔件的通孔与曲轴之间的润滑油引入到气缸的滑片槽中，以对滑片槽中的滑片进行润滑。此处的气缸可以为第一气缸或第二气缸，还可以为第一气缸和第二气缸。
对于原有的压缩机，当润滑油的液面高度低于滑片时，润滑油不能对滑片进行润滑，容易磨损滑片等零部件。通过本实施例的技术方案，即使润滑油的液面高度低于滑片，在曲轴的转动带动下，通孔与曲轴之间的润滑油可顺次通过第一通道40和第三通道60进入到滑片槽内，从而对滑片等部件进行润滑。因此本实施例的技术方案还能够在油量不足的情况下保证滑片的润滑，从而保证压缩机的可靠性。
在本实施例中，第三通道60具有两个出口，第三通道60的两个出口分别位于第一端面和第二端面上，第三通道60为多个，多个第三通道60沿第一通道40的延伸方向间隔设置。当第一气缸与第二气缸按照相同的位置布置时，可通过第三通道60的两个出口分别向第一气缸和第二气缸的滑片槽内提供润滑油，从而保证第一气缸和第二气缸内的滑片都能得到良好的润滑。
如图1所示，本体10为环形结构，第一通道40沿本体10的径向延伸，第三通道60沿本体10的轴向延伸。如此设置可以便于第一通道40和第三通道60的加工，从而降低间隔件的制造成本。
在本实施例中，间隔件还包括第四通道70，第四通道70设置在本体10上，第四通道70的入口与导油腔30的出口连通，第四通道70的出口位于本体10的外侧面。通过设置第四通道70，能够加强对润滑油的引导作用，从而便于润滑油的流动，提高对冷媒的冷却效果。
具体地，可以将导油腔30靠近第四通道70的端面与第一通道40的轴线之间的夹角设置为180°至220°，同时，将导油腔30靠近第一通道40的端面与第一通道的轴线之间的夹角的值设置的较小，从而提高导油腔30的体积，以使导油腔30储存较多的润滑油，进而提高对冷媒的冷却效果。
间隔件可以设置为一体式结构，也可以设置为分体式结构。在本实施例中，本体10包括第一隔板11和第二隔板12，第一隔板11与第二隔板12配合连接。其中，第一端面位于第一隔板11上，第一隔板11上设置有第一孔段，第二端面位于第二隔板12上，第二隔板12上设置有第二孔段，第一孔段与第二孔段配合形成通孔20，导油腔30位于第一隔板11与第二隔板12之间。导油腔30可以设置在第一隔板11上，也可以设置在第二隔板12上，还可以同时设置在第一隔板11和第二隔板12上。将间隔件设置为分体式结构，加工出导油腔30后再将第一隔板11和第二隔板12配合连接，能够便于间隔件的加工，降低间隔件的制造成本。
如图3至图6所示，第一隔板11上与第一端面对应的一侧设置有第一导油槽31，第二隔板12上与第二端面对应的一侧设置有第二导油槽32，第二导油槽32与第一导油槽31配合形成导油腔30。可以将第一导油槽31与第一孔段连通，也可以将第二导油槽32与第二孔段连通。如此设置，不但可以便于导油腔30的加工，而且能够使导油腔30与相邻的两个气缸的距离相同或接近，从而使润滑油对两个气缸的冷却效果相同或相近。
可选地，在本实施例中，第一隔板11与第二隔板12相对于第一隔板11与第二隔板12的配合面对称。如此设置可以便于间隔件的加工并且使润滑油对两个气缸的冷却效果相同或相近。除导油腔30之外，第一通道40、第二通道50、第三通道60、第四通道70均可同时设置在第一隔板11和第二隔板12上。先在第一隔板11和第二隔板12上加工出槽状结构，然后将对应的槽状结构拼合成通道，既可以便于通道的加工，又可以保证通道的密封效果。
为了保证润滑油的冷却效果，可以将第一隔板11上第一导油槽31的深度设置为大于其他槽状结构的深度，相应地，将第二隔板12上第二导油槽32的深度设置为大于其他槽状结构的深度。这样可以使导油腔30内存储较多的润滑油，以提高对冷媒的冷却效果，防止吸气过热。
如图7所示，本发明的另一实施例提供了一种泵体，泵体包括间隔件、第一气缸200、第二气缸300和曲轴400。其中，间隔件设置在第一气缸200与第二气缸300之间，曲轴400顺次穿设在第一气缸200、间隔件和第二气缸300上，并且间隔件为上述实施例提供的间隔件。
应用本实施例的技术方案，在间隔件的本体10上设置导油腔30，并将导油腔30与本体10上的通孔20连通，这样压缩机在工作时，曲轴与通孔20之间的润滑油能够流动到导油腔30内，导油腔30内温度相对较低的润滑油通过热传导可对第一气缸或第二气缸内的冷媒进行冷却，从而能够降低冷媒的温度，提高压缩机的能效。
如图8和图9所示，本发明的又一实施例提供了一种压缩机，压缩机包括上述实施例提供的泵体。本实施例提供的压缩机在工作时，曲轴与通孔20之间的润滑油能够流动到导油腔30内，导油腔30内温度相对较低的润滑油通过热传导可对第一气缸或第二气缸内的冷媒进行冷却，从而能够降低冷媒的温度，提高压缩机的能效。具体地，可通过导油腔30内的润滑油对第一气缸和第二气缸的吸气腔内的冷媒进行冷却，从而防止吸气过热。压缩机内部或冷媒中的润滑油可以循环流动，从而持续地对冷媒进行冷却。进一步地，通过在间隔件内设置第三通道60，可以将间隔件的通孔与曲轴之间的润滑油引入到气缸的滑片槽中，以对滑片槽中的滑片进行润滑。本实施例的技术方案还能够在油量不足的情况下保证滑片的润滑，从而保证压缩机的可靠性。
