Title:
VARIABLE CAPACITY TYPE SWING PLATE TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JPS61237891
Kind Code:
A
Abstract:

PURPOSE: To sufficiently hold lubricating oil in a crank chamber by allowing the inlet of a pressure adjusting valve in a crank chamber to communicate to the lower part of a high-pressure chamber, in a swing plate type compressor which controls the tilt angle of a swash plate by the pressure in the crank chamber.

CONSTITUTION: Though the tilt angle of the swash plate of a swing plate type compressor is controlled according to the magnitude of the pressure in a crank chamber 7, a pressure adjusting valve 26 is installed between a high pressure chamber 27 and the crank chamber 7 in order to adjust the pressure in the crank chamber 7. One of the inlets on the high-pressure chamber 27 side which communicates to the pressure adjusting valve 26 forms an oil introducing passage 32a communicating to the lower part of the high-pressure chamber 27, and when high-pressure fluid is introduced into the crank chamber 7 from the high-pressure chamber 27 by the opening movement of the pressure adjusting valve 26, also the lubricating oil accumulated in the lower part of the high- pressure chamber 27 is returned into the crank chamber 7 at the same time. Therefore, the lubricating oil can be sufficiently held into the crank chamber 7, and a compressor can be favorably lubricated.
