Problems solved by technology

[0006] As mentioned above, the vane compressor using the pressure of the centrifugal pump and its own discharge pressure starts to increase the vane back pressure after starting, so the start-up delay increases accordingly, and the time for the start-up oscillation to occur becomes longer.

Abstract

A vane compressor (1) able to prevent the start delay and start oscillation including: a cylinder chamber (3); a rotor (5) rotatably arranged in the cylinder chamber (3); vane grooves (7) provided in the rotor (5) at equal intervals in the circumferential direction thereof; vanes (9) arranged in the vane grooves (7) in a way that the vanes (9) are capable of protruding to, and retracting from, the cylinder chamber (3); and the vane back-pressure chamber (11) communicating with the bottom portions of the vane grooves (7), and configured to apply the back pressure to the vanes (9); and a back-pressure supplying unit (13) configured to transmit the pressure to the vane back-pressure chamber (11), and to push up the vanes to the sliding surface of the cylinder chamber (3) once the activation mode for rotating the rotor (5) is selected.

Description

technical field [0001] The present invention relates to a vane compressor in which a compression chamber is formed in a cylinder chamber by vanes protruding from a rotor. Background technique [0002] As a conventional example of a vane compressor, there is a vane compressor disclosed in Patent Document 1. As shown in FIG. When the rotor rotates, the vane of the vane groove is pushed out by the centrifugal force and the back pressure generated by the discharge pressure to come into close contact with the sliding surface of the cylinder chamber, and the vane compressor starts to compress the gas. Furthermore, in order to promote vane movement and close contact between the vane and the sliding surface of the cylinder chamber at startup, a centrifugal pump driven by the rotation of the rotor is provided, and back pressure is sent from the centrifugal pump to the vane back pressure chamber. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-190509 [0004] However,...
