在一些实施例中，曲轴2内设有多条润滑油道22，润滑油道22在曲轴2表面形成多个润滑油孔221，润滑油道22内充有润滑油，用于对曲轴2进行润滑。如图7-9所示，在曲轴2内设有润滑油道22，润滑油道22穿出曲轴2表面形成润滑油孔221，润滑油通过润滑油道22经润滑油孔221流出对曲轴2进行润滑。
在一些实施例中，润滑油道22包括直孔222和斜孔223，直孔222与斜孔223的夹角大于120度。如图7-9所示，润滑油道22内的直孔222与斜孔223的夹角大于120度，避免锐角过液造成的润滑油液运动方向剧烈变化，可以获得更稳定的润滑输出和更小的压力损失。
在一些实施例中，柱塞泵还包括空气过滤器6，空气过滤器6设在箱体1上，且与第一腔室121相连，用于向第一腔室121内通入空气。如图1-6所示，第一腔室121的顶部设有空气过滤器6，空气过滤器6将进入第一腔室121的空气进行过滤，防止空气中的异物进入第一腔室121内。
在一些实施例中，空气过滤器6还包括挡板61，挡板61位于空气过滤器6外部，用于对空气过滤器6进行保护。如图6所示，挡板61上带有合页和镂空，在保护空气过滤器6的同时不影响空气进入。
在一些实施例中，箱体1由铸铁制成。铸铁具有较好的力学性能和经济价值，适合制作箱体1。
