Abstract

The hydraulic jack has a plunger (10) operating inside the cylinder (12). The plunger is connected to the moving table (14). The hydraulic press is mounted on a base (22) which supports a fixed table (20). Two pistons (16) are fixed to the mobile plate (14). The cylinders are connected to the hydraulic circuit (24). The regulator system consists of a restriction orifice (28) with a remotely operated by-pass valve(34). The restriction orifice allows flow of the hydraulic fluid out of the hydraulic cylinders, so as to control the movement of the table (14) according to the load applied to it by the main plunger.
