Abstract
A sprinkler head has a valve member retained in a closed position by a latch. The latch is released by a temperature responsive controller in the form of a bulb of frangible material and containing a heat expansible fluid. Compressive loads on the bulb are reduced whereby the bulb may be smaller and thinner than prior bulbs.
