Abstract (en)
[origin: US5016782A] A dispenser for viscous materials has a cylindrical housing with an open end, a hollow cylinder which is reciprocable in the housing and defines a chamber for viscous material. One end of the chamber is adjacent a wall member of the cylinder which is provided with an outlet for viscous material, and the other end of the chamber is adjacent a piston which is mounted on a guide of the housing and is movable with the cylinder only in a direction to extract the cylinder from the housing. The wall member serves to move the entire cylinder in a direction to move the wall member toward the piston and to thereby expel material from the chamber, and the tubular wall of the cylinder adjacent the wall member is used to pull the cylinder in the opposite direction whereby the tubular wall of the cylinder entrains the piston so that the effective volume of the chamber for viscous material remains unchanged during movement of the cylinder in the opposite direction.
