ROOTS TYPE ROTARY COMPRESSOR
A roots type rotary machine includes rotors having a specific profile whereby any vibration and noise generated by the machine is minimized and its efficiency is increased. The number of lobes of each rotor is 3 or more. The tip and root portions of each rotor are defined by circular arcs (2a, 2b),...

| description | A roots type rotary machine includes rotors having a specific profile whereby any vibration and noise generated by the machine is minimized and its efficiency is increased. The number of lobes of each rotor is 3 or more. The tip and root portions of each rotor are defined by circular arcs (2a, 2b), respectively, which are made smoothly continuous with each other through an involute curve (2C). The ratio of the diameter (D') of the tip circle to the diameter (d') of the root circle is selected to fall within a range which is given by a specific expression. |
