Abstract
A hydraulic device comprises an outer surface of a rotor rotating and facing an outer surface of a port member. The rotor has a plurality of cylinders disposed about an axis and cooperating pistons. The cylinders communicate with respective open ends at the rotor outer surface. Each open end alternatingly communicates with high and low pressure ports. Each two successive cylinders are interconnected via a fluid displacement member having first and second openings communicating with each respective cylinder and a closure element that obstructs either the first or second opening if the pressure in the cylinder that communicates with the second opening is higher or lower than the pressure in the cylinder that communicates with the first opening, respectively. The first opening and the second opening of each two fluid displacement members which communicate with one cylinder are fluidly connected with that cylinder at opposite sides of a flow resistance.
