Abstract
The thermally responsive actuator described in this disclosure includes a housing, a thermal expansion material, a piston, and a closure assembly. The housing has an internal cavity and an opening that leads into the cavity. The thermal expansion material is placed inside the cavity. The piston extends at least partially through the opening into the cavity. The closure assembly, which includes a cover and a sealing system, is attached to the housing at the opening. It covers the opening and surrounds the piston. The sealing system includes two sealing members: a first and a second. The housing and/or the cover has two separate compartments—one for each sealing member—positioned along the same axis but separated by the cover.
