FEEDER FOR FOAM AND OTHER COATINGS Russian patent published in 2015 - IPC B05B7/00 

FIELD: transport.

SUBSTANCE: invention relates to feeder of foam and other coatings and can be used for making of wind-proof films for isolation of structures from ambient effects. Feeder (10) has fluid carrier (20) that makes a fluid feed channel (25). Besides, said feeder (10) incorporates fluid flow rate regulator (30) controlled by trigger (37) to make flow channel (35) communicated with the channel of fluid carrier (20). One end of flow rate controller (30) and its channel (35) is secured to fluid carrier (20). Fluid can flow via fluid channel when trigger stays in one position. Fluid cannot flow when trigger (37) stays in another position. Feeder (10) comprises also flow-through unit (50) that makes the flow channel (55) communicated with flow rate controller (30) channel and plugged to flow rate controller (30). Flow-through unit (50) doubles as the gas channel to communicate flow channel with inlet. Gas can be forced through said inlet into fluid passing through flow channel. Feeder has orifice (40) composed by either flow-through channel unit (50) or secured as a separate part in flow channel at the flow rate controller end, at flow-through unit inlet or between flow-through unit (50) and controller (30). Orifice (40) features cross-section area smaller than that of flow channel downstream of flow-through unit (50). Besides, feeder (10) includes mixer making the flow channel communicated with flow-through channel. Mixer unit flow channel comprises mixing elements. Feeder can include optional stabilization unit (80) or optional extension unit. Said unit (80) makes the flow channel (85) communicated with mixer unit channel. Said unit (85) makes the flow channel communicated with stabilization unit (80) channel. Gas channel is arranged to feed gas to fluid in flow channel downstream of orifice (40) relative to fluid flow. Invention covers also the method of feeding the foamed and other fluids.

EFFECT: making of wind-proof films for isolation of structures from ambient effects.
