Title:
VANE ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JP2010209773
Kind Code:
A
Abstract:

To provide a vane rotary compressor to be used for air-conditioning a vehicle while preventing the chattering of a vane by raising the back pressure of the vane in a stroke of setting itself in a vane groove to stabilize the behavior of the vane.

The cross section area of the approximately circular groove 9 in a stroke of setting the vane therein through a vane maximum elongation position is reduced to increase flow path resistance during moving fluid in a vane back pressure chamber. Thus, pressure in the vane back pressure chamber 17 is raised to increase the pushing force of the vane 4 against the wall face of a cylinder 1 to stabilize the behavior of the vane, therefore preventing chattering to improve quietness.
