Abstract
An apparatus for producing a solid-forming or foam forming mixture. Feed pipes carry reaction components from storage containers to a mixhead where they merge into a mixing chamber. A separate feed pipe leads into the outlet of the mixing chamber for the introduction of a filler into the reaction mixture. The outlet of the mixing chamber is arranged partially in a tube which is coaxial with a housing. The tube is movable within the housing and acts as a closure for the filler feed pipe.
Claims8
An apparatus comprising:
- (a) storage containers for reaction components;
- (b) feed pipes which lead from the storage containers via metering pumps to a mixhead where the reaction components merge via injection openings into a mixing chamber;
- (c) an outlet passage connected to said mixing chamber, said outlet passage being arranged in a tube that is coaxially mounted in a housing, said tube being movable relative to said housing;
- and (d) a storage container for filler which leads to said outlet passage of said mixing chamber via a filler feed pipe with the coaxial tube being designed as a closure means for said filler feed pipe.
