Abstract
Hydraulic operated blind riveting apparatus includes a pneumatic/hydraulic intensifier 23 and a reservoir 45 of hydraulic fluid for making up loss of hydraulic fluid. The reservoir is connected to the hydraulic system by a quick acting priming valve 47, actuated by the pneumatic feed to the intensifier. This priming valve is arranged to open and close before there is any effective change in pressure in the hydraulic system due to the action of the intensifier.
