FIELD: process engineering.
SUBSTANCE: invention relates to two-component foam sprayer to be used in construction. Proposed sprayer gun comprises two pressure reservoirs 2, 3 housing initial components, initial components transfer channels, initial components proportioning valves and mixing chamber to produce two-component foam. Two pressure reservoirs 2, 3 are arranged in parallel in gun case 1. Said proportioning valves are made up of needle valves. Each valve incorporates orifice to open directly into detachable nozzle 4 accommodating mixing chamber. Connection points of pressure reservoirs are arranged one after another in axial direction. Said pressure reservoirs are arranged, in fact, perpendicular to each other.
EFFECT: simple design, ruling our foam hardening inside gun.
