Technical Problem
[0003]然而，由于泵体需要在高温下使用，若滚针在高温下的形变过大，容易使活塞和滚针之间产生卡顿或卡死现象，导致压缩机无法始终正常运行，这样会影响压缩机的能效，甚至使压缩机产生可靠性问题
Benefits of technology
[0018]在本申请提供一种压缩机，该压缩机将滚针的热膨胀系数设计在预设范围(10×10-6/℃～13×10-6/℃)内，使得滚针在高温下的膨胀量较小，此时活塞1和滚针3在压缩机工作时始终具有一定的间隙，如此能够有效避免活塞1和滚针3在相对移动过程中产生的卡顿或卡死现象，维持压缩机的能效，保证压缩机长期运行的可靠性。

Abstract
The utility model provides a kind of compressor, it is characterized by including piston, sliding vane, roller and cylinder, the piston, the sliding vane and the roller are all located in the cylinder, the roller is limited in the sliding vane end close to the piston, the roller is used to contact with the piston, and can be rolled relative to the piston;The thermal expansion coefficient of the roller is 10×10 ‑6 / ℃~13×10 ‑6 / ℃. The thermal expansion coefficient of the roller in the compressor is set in the preset range, so that the roller has a small deformation amount at high temperature, at this time, the piston and the roller still have a gap during the operation of the compressor, which can effectively prevent the piston and the roller from being stuck, and ensure the reliable operation of the compressor.
