Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but this utility model
It is not limited to these embodiments.
As shown in Figures 1 to 7, a kind of oil pumping device for totally-enclosed frequency-changeable compressor, including bent axle 1, fuel sucking pipe 2,
Stator and for wrapping up described bent axle 1 and the housing of fuel sucking pipe 2, the external cylindrical surface of described bent axle 1 offers finishing bathtray 4.Inhale
Oil pipe 2 is nested with the outside in bent axle 1 bottom, is provided with oil suction tube core 3 in fuel sucking pipe 2.Described fuel sucking pipe 2 and oil suction tube core 3 are equal
It is made of plastics.Fuel sucking pipe 2 and oil suction tube core 3 are by injection one-shot forming.Bent axle 1, fuel sucking pipe 2, oil suction tube core 3 and stator position
On same axis.Offer, on the external cylindrical surface of described bent axle 1 bottom, the stopper slot up and down preventing fuel sucking pipe about 2 play
C, the bottom face of bent axle 1 offers multiple rotary stopper groove d for ensureing bent axle 1 and fuel sucking pipe 2 synchronous axial system, described suction
