Patent ID: 7364054

Claim:
A tool for dispensing one- or multi-component masses contained in cartridges or foil bags, comprising a housing ( 2 ; 32 ); at least one handle ( 4 ; 34 ; 54 ) provide on the housing ( 2 ; 32 ); at least one piston rod ( 5 ; 35 ; 55 ) displaceable in the housing ( 2 ; 32 ); a displacement mechanism ( 6 ; 56 ) for displacing the at least one piston rod ( 5 ; 35 ; 55 ) and having at least one displacement member ( 8 ) and a locking member ( 9 ) which are arranged on the at least one piston rod ( 5 ; 35 ; 55 ), are axially displaceable, and are pivotable in a longitudinal direction of the tool ( 1 ; 31 ; 51 ); a force transmission device ( 21 ; 41 ; 61 ) acting on the displacement member ( 8 ) and having a switching element ( 22 ; 42 ; 62 ) arranged on the handle ( 4 ; 34 ; 54 ), an actuator ( 24 ; 44 ; 64 ) for actuation of the at least one displacement member ( 8 ), and connection means ( 26 ; 46 ; 66 ) for connecting the switching element ( 22 ; 42 ; 62 ) with the actuator ( 24 ; 44 ; 64 ); and at least one actuation member ( 12 ; 57 ) for actuating the switching element ( 22 ; 42 ; 62 ) of the force transmission device ( 21 ; 41 ; 61 ), wherein the switching element ( 22 ; 42 ) and the actuator ( 24 ; 44 ) are formed, respectively, as hydraulic cylinders ( 23 , 25 , 43 , 45 ), and the connection means ( 26 ; 46 ) is formed as a hydraulic conduit.
