Abstract: A dispenser for dispensing viscous and non-viscous materials includes a frame, a material storage positioned within the frame and containing at least one material to be dispensed, and a dispensing mechanism for acting on a piston for dispensing the material from the material storage. The dispensing mechanism includes a driving unit to generate driving energy for causing the dispensing movement of the piston, and an energy buffer to absorb a portion of the energy generated by the driving unit during the dispensing movement of the piston. The energy buffer outputs the absorbed energy over a longer period of time than the driving unit is operated to move the piston.

Abstract: A dispenser dispensing a component of material includes a cartridge to store the material to be dispensed, a dispensing mechanism to urge the material towards an outlet of the cartridge, a trigger configured to activate the dispensing mechanism, and a connection device at a dispensing end of the dispenser to connect the dispenser to a spray applicator, with the spray applicator spraying the material out of the cartridge.
