<p>PURPOSE: To mix fluids with efficient operation by providing a housing having one a pair of inlet chambers and one mixing chamber with piston chambers and adjusting the amt. of a gaseous mixture and a gas mixing ratio by the movement of a piston in its axial direction and the rotation thereof around its axis. CONSTITUTION: The housing member 20 having a pair of the inlet chambers 21, 22 and one mixing chamber 28 is provided with two inlet ports 23 and 24 defined in their contours by the member 20. One of these ports is disposed between a pair of the respective inlet chambers and the mixing chamber so that a pair of the inlet chambers are communicated with the mixing chamber. A piston device 35 dividing the piston chamber 32 arranged with a coaxial relation with the mixing chamber to the first piston chamber 45 and the second piston chambers 44 is arranged across the piston chambers and the mixing chamber. Further, a first passageway 55 connects one of a pair of the inlet chambers and the chamber 45 and a second passageway 56 connects the mixing chamber and the chamber 44. A grip 49 slidingly born by the housing member 20 rotates the piston device 35.</p> |
