Abstract:
An applicator for depositing a one- or multi-component fluid, said applicator comprisinga housing (12), at least one supply container (16) for said fluid, adapted to be mounted to said housing (12), said supply container (16) comprising a discharge opening (28) and having arranged therein a piston (20) for sliding displacement in the direction of said discharge opening (28). an energy storage means (42) comprising a hand-operated tensioning lever (58), pivotally arranged on said housing (12), which, when moved from a rest position into a pulling position, causes movement of a spring tensioning element (54) by which a spring (46) for storage of mechanical energy, having one end (48) fixed on said housing (12), can be transferred from a rest position into a tensioned position, and a moving means (44) for the piston (20) of said supply container (16), said moving means (44) being coupled to said energy storage means (42) and comprising a drive element (66) coupled to the other end (52) of said spring (46), said drive element (66) being adapted to be driven, by the stored mechanical energy of said spring (46) during the transfer from the tensioned position into the rest position of said spring (46), in increments so as to move a press-on element (84) acting on said piston (20) for displacing it in the direction of said discharge opening (28) of said supply container (16).
