摘要： An air compressor that employs splash lubrication to lubricate and cool a piston kit that includes a cylinder and a piston reciprocating in the cylinder. In one form, cooling channels can be coupled to or formed on the cylinder to direct the lubricant that is splashed onto the cylinder to drain in a desired manner, such as helically around the exterior of the cylinder, to more effectively cool the piston kit. In another form, the cylinder can include an annular flange that can be bigger in diameter than a remainder of the cylinder. The annular flange can be received into a counterbore in a cylinder block. A cylinder head, which can be fastened to the cylinder block, can apply a clamping force to the annular flange to clamp or fix the cylinder to cylinder.

摘要： A stator core 510 of a motor 3 has a plurality of oil return passages 530 extending through one surface 510a and the other surface 510b of the core. On the other surface 510b of the stator core 510, a hydraulic diameter of each oil return passage 530 is 5 mm or larger, and a ratio of a total area of the oil return passages 530 to an area of a virtual circle having a diameter equal to a maximum outer diameter of the stator core 510 is 5 to 15%. Thereby, lubricating oil accumulated on the other surface 510b side of the stator core 510 is returned to an oil reservoir 9 through the oil return passages 530, and shortage of oil in the oil reservoir 9 is prevented. Furthermore, a cross sectional area of the stator core 510 can be securely kept, and motor efficiency is maintained.
