The downside to this is that you have to move C1 a hundred inches to move C2 one inch. If the force exerted on C1 is 10 lbf, the force exerted by C2 is 1000 lbf because C2 is a hundred times larger in area ( S = π r²) as C1. Examples Two hydraulic cylinders interconnectedĬylinder C1 is one inch in radius, and cylinder C2 is ten inches in radius. In normal cases, hydraulic ratios are combined with a mechanical force or torque ratio for optimum machine designs such as boom movements and trackdrives for an excavator.
3.1 Five basic types of load-sensing systemsĪ fundamental feature of hydraulic systems is the ability to apply force or torque multiplication in an easy way, independent of the distance between the input and output, without the need for mechanical gears or levers, either by altering the effective areas in two connected cylinders or the effective displacement (cc/rev) between a pump and motor.3 Constant pressure and load-sensing systems.
