ABSTRACT:
A multi-piston assembly is illustrated wherein a cylindrical housing (A) is ported through longitudinal circumferentially spaced ports (F) and (G) carried within the cylindrical housing. Porting through piston rods is thus avoided so that their cross section may be reduced thereby increasing the area of the pistons available for contact by pressurized fluid. Even greater force may be made available for actuating a tool by the addition of an add-on unit utilizing complementary longitudinal porting.
