Abstract
The present invention relates inter alia to a hydraulic device which may be used as a hydraulic transformer. The hydraulic device comprising a housing, a first tubular cavity and a second tubular cavity both being provided within the housing. A piston structure is reciprocatable arranged within the housing and comprises a first piston and a second piston; wherein the first piston divides the first cavity into two chambers, and the second piston divides the second cavity into two chambers. Fluid passages for individually exchanging fluid between the chambers and the exterior of the housing are provided and each fluid passage comprising a controllable shut-off valve so as to provide the reciprocating movement of the piston structure by exchanging fluid between exterior and the two chambers of the first cavity, and said hydraulic transformed being configured to control the shut-off valves to selectively be in a closed state or in an open state.
