Accumulator Cylinder

Properties according to model
Accumulator cylinders combine the roles of hydraulic cylinders and hydraulic accumulators. This simplifies assembly and reduces the risk of leaks. As the piston rod moves out, pressure is applied to the hydraulic cylinder through a connecting hose on the piston side, and the accumulator on the piston ring side is gradually filled with mineral oil. 

In the end position (piston rod out), pressure equalisation occurs between the piston side and the accumulator on the piston ring side through a valve in the piston. The accumulator now pushes the piston rod in again on removing the pressure on the piston side. BÜTER Group accumulator controlled return stroke cylinders offer our customers clear advantages:

• Half of the valves usually needed can be omitted, with the result that considerable assembly costs are saved
• No pressure decline occurs with the integrated automatic refill valve even after years of use
• The pullback force can precisely be set at a computer-controlled filling point

Accumulator controlled return stroke cylinders with bladder or membrane accumulator show their advantages in confined spaces, where a mechanical spring would be unsuitable for reasons of safety and too low spring tension – or where the accumulator serves as overload protection and damper.
