Abstract

PURPOSE:To provide a multi-stage fluid pressure cylinder with compacted construction by using the hollow piston head of the first-stage fluid cylinder as the second-stage fluid cylinder, and by constructing this second-stage piston head hollow so as to allow intrusion of the third-stage piston head. CONSTITUTION:The piston head 3 of first-stage fluid cylinder 1 is constructed hollow so as to be used as a second-stage fluid cylinder, and the piston head mating therewith is made also hollow to allow intrusion of a third-stage piston head. In contrast to a conventional fluid pressure cylinder, which works with a large power, but has a body in a size half of its work to cause restricted usage, this cylinder works with a large power from its compacted construction to provide use for, various purposes. In the attached illustration, 4, 5 and 6 are a fluid pressure cylinder cover, piston and fluid pressure lead-in hose, respectively.
