Revolving actuator for hydraulic revolving a shaft, comprising a bowl rotor (3) arranged axially rotatable in a housing comprising two housing halves (1, 2), where the bowl rotor (3) is adapted to be connected with a shaft and thereby providing an upper spheric bearing for the shaft, passages thereby providing the housing halves (1, 2) with pressurized hydraulic fluid, the inner walls of the two housing parts (1, 2) thereby having a spheric shape and being sealingly abutting against the bowl rotor (3), the bowl rotor (3) comprising a circumferential recess (4) at the equator, the bowl rotor (3) having at least one partition wall (5) closing the recess (4), a cylinder limitation (8) being arranged in each recess (4) and being rigidly connected with the housing halves (1, 2), and hydraulic connections to the cylinder rooms (6, 7) established in the recesses (4) thereby ensuring supply of hydraulic pressure in the cylinder rooms (6, 7) at each side of each partition wall (5). |
