一对相互啮合的按一定传动比反向旋转的螺旋形转子，水平且平行配置于机体内部，具有凸齿的转子为阳转子，通常它与原动机连接，功率由此输入。
具有凹齿的转子称为阴转子。
在阴、阳转子的两端（吸气端和排气端）各有一只滚柱轴承承受径向力量，在两转子的排气端各有一只四点轴承，该轴承承受轴向推力。
位于阳转子吸气端轴颈尾部的平衡活塞起平衡轴向力减少四点轴承的负荷的作用。
在阴、阳转子的下部，装有一个由油缸内油活塞带动的能量调节滑阀，由电磁（或手动）换向阀控制，可以在15%~100%范围内实现制冷量的无级调节，并能保证压缩机处于低位启动，以达到小的启动扭矩，滑阀的工作位置可通过能量传感机构转换为能量百分数，并且在机组的控制盘上显示出来。
为了使螺杆压缩机运行时其外压比等于或接近机器的内压比，使机器耗功最小，压缩机内部设置了内容积比调节滑阀，由电磁（或手动）换向阀控制油缸内油的流动推动油活塞从而带动内容积比滑阀移动，其工作位置通过内容积比测定机构转换为内压力比值在机组的控制盘上显示出来。

When a Non-Road engine runs on high sulfur fuel, it is advisable to use a "CF or better" classification engine oil with a high Total Base Number (a minimum TBN of 10 is recommended).A Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed. : Recommendable X : Not recommendable* TBN: Total Base Number **FuelA Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable emissionregulations for the area in which the engine is operated.A Use of diesel fuel with sulfur content less than 0.10 % (1000 ppm) is strongly recommended.A If high-sulfur fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm)) is used as a diesel fuel, change the engineoil and oil filter at shorter intervals. (approximately half).A DO NOT USE Fuels that have sulfur content greater than 1.0 % (10000 ppm).A Since KUBOTA diesel engines of less than 56 kW (75 hp) utilize EPA Tier 4 and Interim Tier 4 standards, the use oflow sulfur fuel or ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated areas.Therefore, please use No.2-D S500 or S15 diesel fuel as an alternative to No.2-D, and use No.1-D S500 or S15 diesel fuel as an alternative to No.1-D for ambient temperatures below -10 (14 ).1) No.1-D or No.2-D, S500 : Low Sulfur Diesel (LSD) less than 500 ppm or 0.05 wt.% No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%A CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and is NotRecommended for use in Kubota E3 specification engines.Models*Oil pan depth124 mm (4.88 in.)*90 mm (3.54 in.)D1503-M-E3 D1703-M-E3 D1803-M-E3 V2003-M-E3 V2203-M-E3 V2403-M-E3 V2403-M-T-E3200 Hrs 150 HrsInitial 50 HrsLubricating oil classification**FuelRemarks Low-sulfur High-sulfurCF *TBN10CF-4X CG-4X CH-4X CI-4X。
