The utility model discloses a rotor compressor includes: the valve comprises a shell 1 and a valve plate 2, wherein an exhaust port 11 is formed in the shell 1; the valve plate 2 is arranged outside the shell 1, the valve plate 2 comprises a body part 21 and a protruding part 22 which are mutually connected, the body part 21 is connected with the shell 1, and the body part 21 can be arranged in a deformable manner, so that the protruding part 22 has a blocking position for blocking the exhaust port 11 and an avoiding position for avoiding the exhaust port 11; wherein, when the convex part 22 is in the blocking position, the convex part 22 is in line contact with the shell 1. The body portion 21 of the valve sheet 2 is deformable so that the protrusion 22 has a blocking position and a retracted position, when the protrusion 22 is in the blocking position, the protrusion 22 is in line contact with the housing 1 to index the exhaust port 11, and when the protrusion 22 is in the retracted position, the protrusion 22 is spaced from the housing 1 to allow the exhaust port 11 to communicate the space inside and outside the housing 1, so as to facilitate the exhaust of the rotor compressor. Through adopting this kind of structural design, not only realized opening or closing of rotor compressor gas vent 11, moreover, because when bellying 22 was in the shutoff position, bellying 22 was line contact with shell 1, can reduce the friction of bellying 22 and shell 1 contact position effectively to make things convenient for bellying 22 to switch between shutoff position and dodge the position, reduce the exhaust loss, with the great problem of the exhaust loss of solving the rotor compressor among the prior art.
The projection 22 is provided on the side of the body portion 21 close to the housing 1, and is provided projecting toward the housing 1.
Specifically, the arrangement of the protruding portion 22 may be various:
in one embodiment, the surface of the boss 22 near the housing 1 is an arc-shaped surface.
In another alternative embodiment, the surface of the boss 22 adjacent to the housing 1 is a conical surface.
Through setting up the surface that is close to shell 1 with bellying 22 to arcwall face or conical surface, can also play the effect of direction to the air current to can further reduce exhaust loss, compare with the scheme of conical surface, the structure manufacturing process of arcwall face is better.
