4Q®Continuum® is the new, revolutionary invention of Settima Meccanica in the field of ultra-silent four-quadrants hydraulic.
It's the evolution of the successful Continuum® technology, invented and patented by Settima more than 20 years ago.

4Q®Continuum® technology is internationally patented and based on bi-helical rotors.
The main purpose of its four-quadrants functioning is to recover energy and it's typical of closed loop circuits.
In addition to the ultra-silent advantages, the 4Q®Continuum® technology provides energy regeneration. When necessary, it can be implemented to hoist and lower positive and negative loads in a controlled way.

In addition to this, Settima Meccanica has recently developed a high-performance integrated solution which combines the 4Q® Continuum® pump with SpinRel® motor.
It meets the growing demands for energy-saving options in industrial and mobile productions or electrification applications, where energy efficiency is synonymous with extensive range and reduced battery size.

4Q® Continuum® + SpinRel® electro-hydraulic solution allows to transform the recovered flow into electrical energy and store it in a battery, thus being able to reach the maximum in terms of energy recovery amount.

Furthermore, the 4Q®Continuum® technology allows to significantly simplify the hydraulic circuit.
For example, both pump deliveries could be connected directly to the cylinder. In this way it's possible to control the actuator in both directions. The speed of the electric motor determines the flow rate and, consequently, the speed of the actuator. The direction of rotation determines the direction of movement of the actuator and the motor torque control allows to regulate the pressure available in the system.
Almost no further components are required for the operation (directional valves and flow control valves can be eliminated).
