Abstract
A compression device includes an air cylinder (31); an upper bearing (4) and a lower bearing (5); a piston (71) which defines a working space; a first slide vane (81) and a second slide vane (82) which separate the working space into a first and a second working chamber; a first air suction port (101) and a second air suction port (102) both of which are in communication with the working space; and a first air discharge port (91) and a second air discharge port (92) both of which are in communication with the working space. The first and the second air suction port satisfy the following condition: 0.25≤(V1/S1)*(S2/V2)≤4, where VI and V2 are respectively the maximum volume of the first and the second working chamber, and S1 and S2 are respectively the opening area of the first and the second air suction port.
