Abstract
A fluid system is described, which comprises first and second cylinders, each of which comprises a piston, and a first end and a second end corresponding to full stroke positions of the corresponding piston. The first ends and second ends of the two cylinders thereby define four cylinder ends. The first and second cylinders are fluidly coupled to each other via a first matched pair of cylinder ends selected from the first ends or the second ends. The system includes first and second bypass devices. The bypass devices are each configured so that when a full stroke position is occupied at a respective bypass end from among the four cylinder ends by the corresponding piston, the respective bypass device opens an outlet that allows a flow from the respective cylinder to bypass to a conduit coupled to the respective bypass end. This allows for the two cylinders to self-correct any tendency to lose synchronization with each other, and allows the system to balance pressure between the two cylinders.
