A check valve is provided which may be integrated into a scroll compressor that prevents static cohesion sticking forces between a valve disc member and a retainer member of the check valve housing. Such static cohesion sticking forces may be particularly generated due to oil mist generation in such scroll compressors which create a thin lubricant film between the valve disc and the stop plate of the check valve housing, creating suction type static cohesion when dislodgment of the valve disc away from the stop plate is attempted. A relief region is created between the retainer and the valve disc creating a minimal contact surface area that greatly reduces and / or eliminates such static cohesion sticking forces. For example, the valve disc may be dished to have a concave surface that faces the retainer element provided by the stop plate.
