Claim 0:
1. A flow control valve, applicable in a compressor, comprising:
a valve body, comprising an inlet configured for a fluid to flow into the valve body and an outlet configured for the fluid to flow out of the valve body;
a passage configured between the inlet and the outlet and extending in a predetermined direction, an area of a cross section of the passage perpendicular to the predetermined direction being negatively correlated with a distance from the cross section to the inlet;
a valve element slidably configured in the passage, a flow area between the valve element and an inner wall of the passage being negatively correlated with a distance from the valve element to the inlet, wherein the valve element is slidable in the predetermined direction and is rotatable in response to rotation of a driving shaft in the compressor; and
an elastic member arranged in the valve body and configured to apply an elastic force on the valve element to move the valve element in a direction toward the inlet.
