Abstract
A pneumatic-hydraulic tool for setting two-part fasteners, for example pull-type blind riveting assemblies, has a power unit comprising a thrust member and pulling means actuated by pistons slidable, one behind the other, in a common cylinder. The pistons advance and retract as a whole under the influence of air pressure, and are separable to effect a fastener-setting stroke by admission of hydraulic fluid under high pressure between the pistons. Hydraulic fluid can be admitted and expelled to and from the cylinder between the pistons wherever along the cylinder the pistons may be.
