A fluid mixing device for, for example, mixing of the pigment carrier and the hardener of a two-component paint, comprising a mixing chamber and a resilient membrane dividing the mixing chamber into two compartments. The compartments have separate inlets and a common outlet, the common outlet being arranged so as to continuously communicate with one of the compartments but to be open toward the separate inlets only when the membrane is pressed off a seat surrounding the outlet. The membrane, which is formed with a central opening for maintaining the continuous communication between the outlet and one of the compartments, is preloaded toward its seat so as to break the communication between the outlet and the other of the compartments as the ratio between the fluid pressures in the compartments is below a certain level. The mixing device may be incorporated in the handle of a spray gun, wherein a mixing tube is connected at its outlet to accomplish a final mixing. |
