FIELD: geological exploration. SUBSTANCE: foam generator has housing with branch pipes for intaking the ejected and working media and also for mixture outlet. Cylindrical insertion with built-in ejector insert for liquid flow formation is mounted inside housing. The cavity of cylindrical insertion is in communication with ring-shaped chamber and tangential branch pipe due to holes made in insertion walls. Holes are made in the diffuser of ejector insert. Nets with balls placed on them are fastened at the output of foaming chamber. The balls are made of magnetic ferrite material, the housing and ejector insert of non-magnetic material. The ball bodies have holes for obtaining smaller foam bubbles due to cavitation processes. EFFECT: enhanced quality of foam. 2 cl, 2 dwg
