<p>A gravity and acceleration responsive valve apparatus (56, 72) having a housing (88) with a number of inlet ports (92, 94, 95, 96) through which communication is controlled by respective valve members (104, 106, 107, 108). The valve members (104, 106, 107, 108) in conjunction with space maintaining weight transfer means (126, 128, 129, 130) movable in the housing (88) respond to acceleration force and to gravity to open only selected inlet ports while maintaining all other ports closed. The valve has utility particularly as a tank vent or liquid pickup valve aboard aircraft.</p> |
