VERTICAL COMPRESSOR Russian patent published in 2004 - IPC

FIELD: cryogenic engineering. SUBSTANCE: proposed compressor is furnished with oil baffle made in form of flat cylinder to divide compressor housing into spaces. Suction valves of cylinders communicate with first space through tubes installed in oil baffle with clearance. Suction branch pipe is connected with second space. Oil baffle is installed over cylinders and is rigidly secured to inner walls of housing over entire contour. Each of gas flow guides is made in form of hollow cylindrical cup with closed end face and conical lower part. Central hole is made in conical rear part. Each gas flow guide contains two rows of holes in cylindrical surface. Gas flow guide is connected to oil baffle so that one row of its holes in located in first space of housing. Second row of holes is located in second space of housing. Sum of areas of holes of cylinder suction valves is less than sum of areas of holes of each row of cylinder cup. EFFECT: improved performance characteristics of compressor. 3 cl, 4 dwg
