Claims

[Claims for Utility Model Registration] N through-holes 11, such as first, second, etc., which are parallel to the fluid flow direction and are equally spaced on the same circumference.
A first valve gland 11 having diameters a to 11d, and first, second, ..., Nth through holes 12 that are parallel to the fluid flow direction and provided at equal intervals on the same circumference.
a second valve gland 12 having a to 12d; and the first and second valve glands 11, 12.
The through holes 11a to 11d, 1 of the first and second valve glands are rotatably sandwiched between them.
Openings 13a to 13d, 1 facing 2a to 12d
3a' to 13d' are provided on each end face of the valve seat 13, and the through holes 11a to 11d, 12a to 12d of the first and second valve glands are provided before and after the rotation of the valve seats 11 and 12. A rotary valve characterized in that linear communication holes A to D are provided between the openings 13a to 13d and 13a' to 13d' of the valve seat so that the combinations of communication are different.
