The method of claim 1, Ports of the housing are arranged at an angular interval of 90 degrees, each groove being at an angle of 120 degrees between the first end, the center of the rotor and the second end to correspond to the inlet and outlet ports with each groove disposed in the housing. Multidirectional valve, characterized in that. The method of claim 1, The rotor further includes a through passage formed therein, and both ends of the through passage have an angular interval of 30 degrees or 60 degrees with the ends of neighboring grooves, and both ends of the through passage are rotated according to the rotation of the rotor. A multidirectional valve, each corresponding to a port. The multidirectional valve according to claim 2, wherein the through passage is formed on a line passing through the center of the rotating body. A housing in which the fluid inlet horizontal port and the fluid outlet horizontal port are disposed; And a rotating body accommodated in a rotatable state in the housing, The horizontal ports of the housing are arranged at angular intervals from adjacent horizontal ports on the same plane, The rotor includes at least one through passage extending toward the center thereof, wherein the through passages are connected to each other at the center so that the outer ends of the at least two through passages correspond to the horizontal ports of the housing, respectively, as the ball rotates. Multi-directional valve. The method of claim 6, The horizontal port of the housing is arranged at an angular interval of 90 degrees, wherein each through-path formed in the rotating body is characterized in that the angular interval of the drainage of 30 degrees with the neighboring through passage. The method according to claim 6 or 7, The housing further comprises a vertical port disposed in a state perpendicular to the horizontal port, The rotating body further comprises a horizontal groove formed on the outer peripheral surface corresponding to the horizontal port of the housing and the vertical groove connecting the horizontal groove and the vertical port of the housing. The method of claim 8, The rotating body is formed on the outer circumferential surface of the multi-directional valve further comprises a horizontal groove for connecting any one horizontal port of the vertical groove and the housing. A housing in which the fluid inlet horizontal port and the fluid outlet horizontal port are disposed; And a rotating body accommodated in a rotatable state in the housing, The housing further includes a horizontal port and an inclined port disposed to be inclined in a height direction, wherein the horizontal port of the housing is disposed at an angular interval from an adjacent horizontal port on the same plane, The rotating body is formed on the outer circumferential surface corresponding to the line connecting the points at the same distance from the top or bottom of the annular groove corresponding to the inclined port of the housing; A first horizontal groove formed on an outer circumferential surface and corresponding to a horizontal port of the housing according to the rotation of the rotor; And a first vertical groove connecting the first horizontal groove and the annular groove. The method of claim 10, The housing further comprises a vertical port formed in any portion of the upper or lower, The rotating body further includes a second horizontal groove formed on an outer circumferential surface and corresponding to a horizontal port of the housing, and a second vertical groove formed on the outer circumferential surface and connecting the second horizontal groove and the vertical port of the housing. valve. The multidirectional valve according to any one of claims 1 to 11, wherein the rotating body is any one of a cylindrical body, a sphere, or an ellipsoid.
