A STATIONARY VANE TYPE COMPRESSOR

摘要

A stationary vane type compressor comprises a rotor (1), a cylinder (2), a vane (3), a rotary column (4) and end closures. The rotor is eccentrically disposed in the cylinder. An axis of the rotor rotates about that of the cylinder. An outer surface of the rotor is tangent to an inner circumferential surface of the cylinder and cooperates with it. The outer end of the vane fixedly connects with the cylinder, and two lateral ends of it fixedly connect with two corresponding end closures respectively. A circular slot (5) is provided in the rotor. The rotary column is fitted in the circular slot and rotatably matches with it. A flat slide slot (6) is provided in the rotary column. The vane inserts into the slide slot and slidably matches with it. The cylinder, the vane and the end closures are all arranged in a stationary manner, so that the fit clearance and the relative movement between the cylinder and the vane or between the vane and the end closures are eliminated, and the friction loss and the leakage loss between them are reduced. On the other hand, the vane is not a movable member, so it is unnecessary to consider the dynamic balancing of the vane. That is to say, the dynamic balancing of the compressor can be simplified.
