ABSTRACT:
A casing (11, 12) holds an actuator (18) having a stem (21) that is moves a plunger with substantial force in response to the actuator (18) being heated. The movement of the plunger (22) loads a compression spring (23) that is located between a base end of the plunger (22) and an opposing end wall of the casing. Two longitudinal casing sections (11, 12) form arcuate projections (43, 44) on the opposing end wall (49) which are inserted within at least one coil of the spring with an interference fit to hold the casing half sections together. Beams (64, 65, 74, 75) adjacent the base end wall (17) add support against the thrust reaction movement of the actuator housing (18) in response to movement of the plunger (22) against the compression spring (23).
