Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by patent protection in right of the present utility model.
Embodiment 1: a kind of oil absorption filter, including the housing 1 with hollow chamber, housing 1 one end offers oil-in 16, the other end is provided with oil-out 10, the filter element 2 for filtering fluid it is provided with between described oil-in 16 and oil-out 10, wherein: described oil-out 10 is some elliptical apertures being distributed in housing 1 circumference, and the short axle of all of elliptical aperture is on the same line, elliptical aperture is utilized to replace original circular hole, and each elliptical aperture is relative with its short axle, under same traffic, compared to circular port, spacing between each two adjacent ellipses hole increases, thus effectively strengthening the intensity of oil-in 16, deformation effect uses because hydraulic pressure is too high to prevent oil-in 16.Referring to Figure of description 2 it can be seen that the short axle of described elliptical aperture is arranged in same level.The arrangement making elliptical aperture is more uniform, and all positive cloth of each elliptical aperture is on housing, has been also convenient for the processing of oil-in 16.
