PURPOSE:To make the occurrence of vibrations and noises preventable, by setting up each eccentric rotor so as to cause the position of a sliding member to be displaced in the rotative direction, while making the discharge cycle of a fluid to be lapped in an alternate manner. CONSTITUTION:Starting a driving machine being interlocked with a shaft 7, when both rotors 8 and 8 are rotated inside a pump room 1a, a chamber lying between sliding members 11 and 11 delivers the fluid sucked in from a suction port 16 to a discharge port 15. In these rotors 8 and 8 at both sides, since the configuration of these sliding members 11 is displaced in a rotation direction, the discharge cycle of the fluid fed out of the chamber between these sliding members 11 is lapped at both sides in consequence, thus the fluid discharge continues in succession so that smooth operation can be performed without producing vibrations and noises. |
