[origin: EP1574261A2] The pump (1) for applying powder has a working space (5)with adjustable volume, a powder inlet (6) abutting into the space to intake powder(2), and a powder outlet (9) flowing out of the space to force out the powder in the workspace. It has a moveable piston (12) with one surface adjacent to the workspace which sucks the powder through the powder intake into the workspace using an upwards motion. The piston is pneumatically powered, a control space (15) is created on the other side of the piston from the working space to drive the pump .
