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 4):
A rotary actuator according to  claim 2 , wherein the other of said outer piston part guide and said first part guide and the other of said inner piston part guide and said second part guide are formed as a guide protrusion.
