Abstract
PURPOSE: To devise to reduce the rotary power of a screw rotor according to the compressing pressure and the discharge gas amount by providing a throttling mechanism of a flow passage on the side of a fluid suction chamber to regulate the sucked gas pressure for compression.
CONSTITUTION: A throttling mechanism 13 for a flow passage 12 is provided on the side of a fluid suction chamber 8. When the throttling mechanism 13 is fully opened, the gas of a pressure P0 in the suction chamber 8 is sucked into spaces 1B of a screw rotor 1, and compressed in the compressing process. The gas is given a pressure P2 when it is conducted to a discharge port 7. Meanwhile, when the throttling mechanism 13 is partly closed, the gas is sucked and compressed in a pressure of P0-ΔP=P1, namely, a pressure reduced from the gas pressure P0 in the suction chamber 8 by a throttling resistance ΔP in the throttling mechanism 13, and given a pressure P2 at the discharge port 7. Here, since the throttling resistance ΔP is changed according to the throttling degree, the compressed pressure P2 can be controlled optionally.
