发明名称 ВИНТОВЫЕ КОМПРЕССОРЫ ДЛЯ БОЛЬШИХ МОЩНОСТЕЙ ПРИВОДА
摘要 The invention relates to oil-flooded screw compressors having a male rotor and female rotor each featuring preferably a ratio of male-to-female rotor lobes of 4:6, 5:6 or 5:7. In order to decrease the bearing load at higher working pressures, the profile sections of the rotors are shortened, and an intermediate plate is appropriately arranged in the free space formed.
