Short title	A glass bulb releases a seal and water passes through the orifice to a deflector.
Image title	Left: simplified cross-section of a pendent glass-bulb sprinkler. Water fills the pipe and the orifice down to a seal. A frame with two arms holds a liquid-filled glass bulb against the seal; a toothed deflector sits below the frame. Right: after operation the bulb has shattered, the seal is gone, and water passes through the orifice, strikes the deflector and spreads as a downward spray. Schematic only, not a particular product.
