Abstract

1,128,962. Hydraulic apparatus. ROTARY HOES Ltd. Jan. 20, 1966 [Jan. 27, 1965], No.3503/65. Heading F1P. [Also in Division B5] An hydraulic system for supplying equal volumes of fluid to e. g. at least two identical double-acting press rams 31, 32 so as to operate them simultaneously at the same speed comprises an assembly of ganged pistons 17, 17a driven in separate cylinders by fluid supplied by a pump 33 through a line 37 to one face of each piston so as to displace equal volumes of hydraulic fluid from the opposite faces thereof through ports 23, 25 connected to the rams. The effective areas of the faces of the pistons which displace fluid to the rams are equal. Fluid expelled by the rams 31, 32 returns through lines 42, 43 and a changeover valve 36 to the pump reservoir 35. A hand pump 47 is operable with a valve 46 to provide make-up fluid for the system.
