Abstract

A dosing gun consists substantially of a housing having a trigger device with a trigger lever, with which a piston arranged on a piston rod can be operated evenly by a spring, which spring is initially compressed by a use of the trigger lever and a band brake. For this purpose a cord, which can be wound up onto a cord drum, is secured to an end of the piston rod. A brake drum which is secured an a drive shaft and can be operated by a brake band, is arranged in one piece on the cord drum. With the hand wheel mounted on a left side of the drive shaft, it is possible to wind the cord onto the cord drum and to compress the spring.
