Claim:
An annular-type distributor comprising: a multiple slit layer including at least two annular layers, which are stacked while being spaced by a predetermined distance and in which at least one slit is formed so as to receive or discharge fluid, wherein, when a slit layer aligned at an outermost portion from a center point of the multiple slit layer is referred to as a first slit layer and slit layers sequentially stacked radially inward of the first slit layer are referred to as a second slit layer, a third slit layer, . . . , and an n th slit layer (n is an integer equal to or above 2), respectively, heights of slits formed in the first slit layer are adjusted within a range of 100 to 1000 mm or 10 to 70% of a height H of the annular-type distributor, and the height of the slits formed in the first slit layer is adjusted as follows: if the fluid feeding duct or the fluid discharge duct is located at an angular position of 180° in the annular-type distributor, an angle of 0 to 180° is divided into x regions (x is an integer equal to or above 2) where the height of the slit is individually variable and a region adjacent to an angle of 0° is referred to as a first region and regions sequentially located toward an angle of 180° are referred to as a second region, a third region, . . . , and an x th region, respectively, wherein the height of the slits is gradually increased from the first to x−1 st regions while constantly maintaining the height in each region, and the height of the slits is gradually reduced in the x th region as it reaches the fluid feeding duct or the fluid discharge duct, and the height of the slits formed in the regions corresponding to the angle of 180 to 360° is symmetrically to the height of the slits formed in the regions corresponding to the angle of 0 to 180°.
