Title:
VARIABLE DISPLACEMENT SWASH PRATE COMPRESSOR AND EXTRACTION SIDE CONTROL VALVE
Document Type and Number:
Japanese Patent JP2000064957
Kind Code:
A
Abstract:

To enhance a variable controllability of a displacement by ensuring the feeding of high pressure refrigerant gas to a crank chamber in a variable displacement swash plate compressor of an extraction side control system.

An introduction quantity of refrigerant gas from a crank chamber 3 is controlled by adjusting an opening degree of an extraction side control valve 40 provided on a gas extraction route (36→35 connecting the crank chamber 3 and an inlet port 8 of a compressor to variably adjust an inclined angle of a swash plate. A high pressure correction rod 63 for correcting a set pressure of the control valve 40 by a discharge pressure Pd is movably retained in a guide hole 62 formed on a valve housing 42 of the removing side control valve 40. A gap passage 66 is ensured between an inner periphery of the guide hole 62 and the rod 63 and the high pressure refrigerant gas corresponding to the discharge pressure is fed to the crank chamber 3.
