Abstract

PURPOSE: To improve the volume efficiency through the reduction of the flow resistance in the suction valve device used for a swash plate type compressor for an automobile air conditioner by providing a narrowed portion in a tongue shaped flap at the place where it faces a through hole.
CONSTITUTION: When the pressure in a cylinder 1 starts to decrease and the force pressing down a suction flap 13 exceeds the sum of the pressure in a low pressure chamber and the elastic reaction force of the suction flap 13, the suction flap starts to deflect with its free end being lifted. The gaseous refrigerant passing a through hole 27 is sucked into the cylinder 1 flowing along the deflection curve of the flap 13. When the end of the flap 13 comes in contact with a flap stopper 15 the curve of the flap 13 becomes horizontal or convex toward the cylinder 1 side. This construction reduces the amount of the refrigerant colliding the wall of the flap stopper and becoming a turbulent flow to be sucked into the cylinder through the gap between the flap and the valve place and increases the amount of the refrigerant directly sucked into the cylinder.
