Fluid suction and discharge apparatus

摘要

A fluid suction and discharge apparatus suitable for a compressor for an air-conditioning system for automobiles, having means for extending the life time of the suction reed valve and for suppressing noise due to the vibration of the suction reed valve. A pin having a head of an increased radius is secured to the inner surface of the valve plate with the pin extending through a slit provided in the suction reed valve at a portion between the secured end thereof and the region thereof facing the inlet port in the valve plate, whereby the suction reed valve may be suppressed from overbending. Another means for restricting the bending of the suction reed valve within a predetermined extent may be provided which comprises an axial recess formed in the inner surface of the cylinder from an end thereof facing the valve plate by a predetermined distance, with an extended free end of the suction reed valve being received in the recess.
