Abstract:
1. A dispensing device for dispensing one-component or multi-component masses contained in vessels, comprising at least one piston rod ( 21 ); at least one forward feed mechanism ( 31 ) having at least a first clamping lever ( 32 ) and at least one second clamping lever ( 42 ) each of which is arranged on the piston rod ( 21 ) so as to be axially displaceable and swivelable in longitudinal direction (L) of the dispensing device ( 11 ); at least two spring elements ( 33 , 43 ) acting upon the at least one first clamping lever ( 32 ) and the at least one second clamping lever ( 42 ), respectively; and forward feed means for actuating the at least one first and second levers ( 32 ; 42 ) and having a first forward-feed element ( 34 ) cooperating with the at least one first clamping lever ( 32 ) and a second forward-feed element ( 34 ) cooperating with the at least one second clamping lever ( 42 ), wherein that the first forward feed element ( 34 ) comprises a first eccentric cam ( 36 ) which can be set in rotation and whose outer contour cooperates with the at least one first clamping lever ( 32 ), and the second forward feed element ( 44 ) comprises a second eccentric cam ( 46 ) which can be set in rotation and whose outer contour cooperates with the at least one second clamping lever ( 42 ), and wherein the first eccentric cam ( 36 ) and the second eccentric cam ( 46 ) are arranged on a driveshaft ( 18 ) of a driving mechanism, and eccentricity (E 2 ) of the second eccentric cam ( 46 ) is arranged so as to be offset by 180° to eccentricity (E 1 ) of the first eccentric cam ( 36 ).
