Embodiment
As shown in Figures 2 and 3, the filtration of the utility model compressor oil sump comprises lower shells of compressors 14 and filter sheet 13.Wherein, in the mode of execution shown in Fig. 2, the center portion of filter sheet 13 and the inner wall section of lower shells of compressors 14 are fitted, and the structure of filter sheet 13 as shown in Figure 5.And in the another kind of mode of execution shown in Fig. 3, the center portion of filter sheet 13 and the inwall of lower shells of compressors 14 are fitted completely, the structure of filter sheet 13 as shown in Figure 6.
As shown in Figure 4, the bottom of the bottom of filter sheet 13 and the inwall 14a of lower shells of compressors 14 is fixed together, and filter sheet 13 is positioned at the below of compressor fuel sucking pipe 11.The edge 13b of filter sheet 13 is curved shape, there is gap between bending edge 13c and lower shell body inwall position 14a.The center portion 13d of filter sheet 13 and the inwall position 14a part of lower shells of compressors 14 are fitted.The maximum cross-section width 13a' of the position 13a of filter sheet 13 is less than the wide 8a' of smallest cross-sectional of the position 8a of compressor drum 8, can prevent impurity from dripping to above filter sheet 13 like this.The maximum cross-section width 13a' of the position 13a of filter sheet 13 is greater than the diameter 7a' of the position 7a of compressor crank shaft 7, and the impurity under filter sheet can be prevented like this to be inhaled into bent axle 7.Height (namely 13b top in position is to the perpendicular distance of the upper wall of the center portion 13d of the filter sheet 13) 13b' of the position 13b of filter sheet 13 to be less than bottom fuel sucking pipe 11b to the perpendicular distance 11b' of the upper wall of the center portion 13d of filter sheet 13, so just can prevent when lubricant in compressor deficiency, bent axle 7 is only drawn through the lubricant oil in filter disc 13.
