Patent ID: 11885327

Abstract:
Embodiments of the present disclosure provide a flow control valve, an oil pump assembly having the flow control valve, and a scroll compressor. The flow control valve includes: a valve body having 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 provided 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 provided in the passage, a flow area between the valve element and an inner wall of the passage is negatively correlated with the distance from the valve element to the inlet; and an elastic member provided in the valve body to apply an elastic force on the valve element so as to move the valve element in a direction toward the inlet. Thereby, for example, lubrication of the scroll compressor is improved.
