  • Expulsion device actuated by a pressure medium
    Patent number: 6845896
    Abstract: An expulsion device expels objects or liquid materials from a reservoir using a drive piston which is subjected to the action of a pressure medium. The expulsion device includes a pressure medium container that is exchangeable and connected to a device body. An actuation device enables the pressure medium to act on the drive piston which is thus displaced in a forward and a backward direction.
