Abstract
A hydraulic device comprising a piston arrangement having a plurality of pistons arranged to reciprocate within a respective cylinder. The reciprocation is driven by a rotatable piston drive element. Each piston is associated with a piston switching valve, and each piston switching valve is configured to control fluid flow into and out of the cylinder of the associated piston. A controller is configured to control the piston switching valves. Each of the piston switching valves is configurable between a first configuration in which the associated cylinder is in communication with a first port, and a second configuration in which the associated cylinder is in communication with a second port. The controller is configured to change the configuration of each piston switching valve for each in-stroke and out-stroke of the associated piston.
