Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP2019105195
Kind Code:
A
Abstract:
To provide a compressor in which a check valve mechanism for suppressing a backflow of a refrigerant into a suction path is provided, and which has high reliability regarding inflow suppression of a liquid refrigerant into the compressor.SOLUTION: A compressor compresses a refrigerant sucked from a suction port 23a in a compression chamber and discharges it from a discharge port. The compressor includes: a suction path 90 for guiding the refrigerant sucked from the suction port to the compression chamber; and a check valve mechanism 80. The check valve mechanism is provided in the suction path. The check valve mechanism suppresses the refrigerant back-flowing to the outside of the compressor from the inside of the compressor through the suction port while the operation of the compressor is stopped. The check valve mechanism includes a valve seat 84, a valve body 82, an elastic member 88, and a magnetic force generating member 84. The valve body is provided in the suction path so as to move along the suction path, and it is pressed against the valve seat, and closes the suction path. The elastic member energizes the valve body toward the valve seat. The magnetic force generating member suppresses the movement of the valve body pressed against the valve seat by a magnetic force.SELECTED DRAWING: Figure 2
