Abstract:
The invention relates to a rotary actuator ( 1 ) to be installed between a dipper arm ( 9 ) and an excavator tool ( 12 ) of an excavator ( 2 ). The rotary actuator ( 1 ) comprises a first actuator part ( 20 ) adapted to be fixed to the dipper arm ( 9 ) or to the excavator tool ( 12 ), wherein the first actuator part ( 20 ) is formed with an inner cylindrical orifice ( 23 ) comprising first part guide means ( 24 ). The rotary actuator ( 1 ) further comprises a second actuator part ( 21 ) adapted to be fixed to the other of the dipper arm ( 9 ) or the excavator tool ( 12 ), wherein at least a part of the second actuator part ( 21 ) is arranged inside the inner cylindrical orifice ( 23 ) and wherein the second actuator part ( 21 ) is rotatably supported by the first actuator part ( 20 ) while being substantially axially fixed in relation to the first actuator part ( 20 ). Furthermore, an outer cylindrical surface ( 25 ) of the second actuator part ( 21 ) comprises second part guide means ( 26 ). The rotary actuator ( 1 ) also comprises a piston part ( 22 ) arranged inside the inner cylindrical orifice ( 23 ) and around at least a part of the a second actuator part ( 21 ), wherein the piston part ( 22 ) is axially displaceable in relation to the a first actuator part ( 20 ) and the a second actuator part ( 21 ) and wherein an outer cylindrical piston part surface ( 29 ) is provided with outer piston part guide means ( 35 ) arranged to mesh with the first part guide means ( 24 ) and an inner cylindrical piston part surface ( 30 ) is provided with inner piston part guide means ( 36 ) arranged to mesh with the second part guide means ( 26 ). The second actuator part ( 21 ) is formed as a cantilever and piston means ( 27 ) of the piston part ( 22 ) extends all the way across the free end ( 28 ) of the second actuator part ( 21 ). The invention further relates to a method for tilting an excavator tool ( 12 ) in relation to a dipper arm ( 9 ) of an excavator ( 2 ) by means of a rotary actuator ( 1 ) and use of a rotary actuator ( 1 ).

Claim (Index 7):
A rotary actuator according to  claim 1 , wherein said first actuator part comprises a housing part and an intermediate part, wherein said first part guide are arranged on said intermediate part and wherein said housing part and said intermediate part are rigidly connected.
