  • Device for simultaneously ejecting two fluids, in particular two pyrotechnic fluids
    Patent number: 5419257
    Abstract: A device for simultaneously ejecting two fluids, in particular pyrotechnic fluids, intended to react on contact after ejection includes a reservoir for each fluid open to the exterior of the device through a respective nozzle. The two reservoirs comprise a respective cylinder/piston combination and simultaneous ejection of the two fluids is achieved by displacement of one piston inside the respective cylinder and mechanical coupling of the pistons. The ejection rates are in constant proportion defined by the section of the piston regardless of how full the reservoirs are.
