Title:
VARIABLE CAPACITY COMPRESSOR
Document Type and Number:
Japanese Patent JPS61215469
Kind Code:
A
Abstract:

PURPOSE: To increase the amount of oil in the reduction gas to the crank chamber thus to improve the lubrication performance by coupling between the suction chamber for varying the inclination angle of an inclination board for varying the capacity an the crank chamber through an air supply path while opening one end of said path to the lowermost end of the delivery chamber.

CONSTITUTION: In a variable capacity compressor, a rotary member 17 is rotated through a drive shaft 10 and upon inclination of a rolling inclination board 19 coupled through a pin 18 with said member 17, the piston 13 is reciprocated through a piston rod 14. In accordance to the differential pressure between the suction chamber 4 and the crank chamber 9, the piston stroke will vary to vary the inclination angle of said board 19 thus to control the compression capacity. Here, the delivery chamber 6 and the crank chamber 9 are communicated. An air supply path (23W27) 22 including a path 23 opening to the lowermost portion of the delivery chamber 6 is formed and a gate valve 28 is arranged in the way. Said valve 28 is controlled to close upon exceeding of the pressure in the crank chamber over a setting level by means of a valve control mechanism 39.
