Spray cartridge for holding two fluid components in separate compartments

摘要

A spray cartridge holds two fluid components in separate compartments which are mixed in a single compartment before they are ejected and sprayed. The mixture is ejected by a piston from a valve-controlled outlet. The mixing is effected by a rod which is moved back and forth through a hollow passage within the housing. One end of the rod extends beyond the housing through the spray outlet. The other end is located in the mixing chamber and has a perforated mixing plate. One of the chambers is an annular chamber formed between the housing and mixing rod.
