LIQUID AND GAS JET DEVICE (VERSIONS) Russian patent published in 1999 - IPC

FIELD: evacuation of gaseous media. SUBSTANCE: relation of area of minimal section of mixing chamber to area of inlet section of same chamber is from 0.005 to 0.392 and straight line forming conical surface of narrowing section of mixing chamber or tangent line to each point of curvilinear surface of narrowing section of mixing chamber are inclined with regard to axis of mixing chamber at angle from 30' to 10 deg. In agreement with another version of implementation of proposed device the whole mixing chamber is made narrowing with relation of area of minimal section of mixing chamber to area of inlet section of same chamber is from 0.005 to 0.392 and straight line forming conical surface of mixing chamber narrowing along flow or tangent line to each point of curvilinear surface of mixing chamber narrowing along flow are inclined with regard to axis of mixing chamber at angle from 30' to 10 deg. EFFECT: enhanced operational efficiency of jet device. 8 cl, 3 dwg
