Abstract: A pile arrangement for vibration driving comprises a stem extending in a longitudinal direction between a first end and a second end, the first end being arranged to be positioned below the second end during driving; and a base structure, arranged at or in proximity to the first end, comprising a plurality of longitudinally open cells that are symmetrically arranged around the stem in the cross section of the base structure. Each cell being defined by a plurality of cell walls extending in the longitudinal direction and having a height-to-width-ratio calculated as the longitudinal extension of the shortest cell wall defining the cell divided by a significant distance of the cell's cross section.

Abstract: The present invention relates to an energy transforming unit adapted to convert reciprocating forces into rotating axle movements on at least one force transmitting axle and/or into electrical power. The unit comprises at least one restriction device which is directly connected to the force and which is arranged to forward the incoming reciprocating forces into a movement over at least one conversion module. The energy transforming unit is characterized in that the at least one restriction device is delimiting one, by the energy transforming unit enclosed reciprocating volume which entirely or partly passes through the at least one conversion module. The reciprocating volume can comprise a non-compressible fluid arranged to forward the incoming forces into a reciprocating fluid movement over the at least one conversion module and/or the reciprocating volume can comprise at least one mechanical force transmitting arrangement adapted to the at least one conversion module.

Abstract: The present invention relates to an energy transforming unit adapted to convert reciprocating forces (Fl) into rotating axle movements on at least one force transmitting axle and/or into electrical power. The unit comprises at least one restriction device (3, 4, 5) which is directly connected to the force and which is arranged to forward the incoming reciprocating forces (Fl) into a movement over at least one conversion module (2a-d, 56, 64, 73, 80, 81, 87, Cm). The energy transforming unit is characterized in that the at least one restriction device (3, 4, 5) is delimiting one, by the energy transforming unit enclosed reciprocating volume which entirely or partly passes through the at least one conversion module (2a-d, 56, 64, 73, 80, 81, 87, Cm).
