Viscous liquid spraying equipment - has head with mixing chamber leading to nozzle and insert forming propellant nozzle

摘要

The equipment sprays liq. from a storage vessel, being partic. for a highly-viscous or hardening one. It has a union for a propellant generating a carrier current, into which the liq. is fed via an opening in the vessel. It has a sprayer head (1) with a mixing chamber (3) leading to a mixing nozzle (2). The union (7) for the propellant and the opening (4) lead into the chamber. An insert (9) in the union has a protruding portion with connector to the propellant source, and one inside the chamber, forming a propellant nozzle (14) aimed at the mixing one. This can have a screwed portion engaging with a tapped one (8) in the head. ADVANTAGE - Easy handling of hardening liquids.
