Abstract
A linear actuator with a pair of in-line piston-cylinder combinations, separated by a partition. The combinations are supplied from a common source of fluid under pressure through a single inlet port. A guide pin prevents the uppermost piston from cooking, and serves as an upper limit stop. The pistons are biased into abutment with one another.
