1. A fluid transfer apparatus, comprising:
a rotor housing defining a fluid compression space having an epitrochoid surface;
a rotor disposed in the fluid compression space of the rotor housing so as to divide the fluid compression space of the rotor housing into a plurality of volume variance spaces, and eccentrically coupled to a rotation shaft rotating in place so as to rotate eccentrically within the fluid compression space; and
a rotor housing cover formed to cover the fluid compression space of the rotor housing, and having a rotation shaft penetration hole formed through a center thereof, and a first cover channel and a second cover channel symmetrically formed on opposite sides to each other with respect to the rotation shaft penetration hole,
wherein the rotor housing cover is provided in plurality, disposed to be spaced apart from one another,
wherein the rotor housing is provided in plurality, each disposed between neighboring rotor housing covers thereof,
wherein the rotor is provided in plurality, disposed in the fluid compression spaces of the rotor housings, respectively,
wherein arrangement directions of the rotors are determined based on a direction that centers of the rotors face with respect to the rotation shaft, and each rotor is arranged to face a different direction from those of neighboring rotors thereof,
wherein an arrangement direction of the rotor housing cover is determined based on an arrangement direction of the first cover channel and the second cover channel with respect to the rotation shaft penetration hole, and
wherein the rotor housing cover is arranged to have an angle of 90° with another neighboring rotor housing cover.
