Abstract (en)
[origin: US5921181A] A pneumatic cartridge expressing device is shown for expressing cartridges containing viscous materials. The device has a holder that is axially longer than the cartridge, and a cap that is sealingly fitted over one axial end of the holder with a piston guided within the cap and forced by compressed air against either the one axial end of the holder or against one axial end of the cartridge. Compressed air is provided through an opening in the piston to pressurize the cartridge, and in the case where the piston seals against the one axial end of the holder, also passes into an annular gap between the cartridge and the holder to prevent bulging of the cartridge during expressing of the cartridge. Compressed air is provided through a separate opening in the cap to the annular gap in the case where the piston seals against one axial end of the cartridge.
