Abstract (en)

In a fluid suction/discharge apparatus, a recess is formed with a cylinder and extends from a closed end of the cylinder in the axial direction of the cylinder. The recess comprises deep and shallow recess portions both integral with each other. The shallow recess portion has a bottom to receive a flexible end of the suction reed valve in a suction condition. The deep recess portion forms a passage for fluid while the flexible end of the suction reed valve is received on the bottom of the shallow recess portion. With such structure, the passage for the fluid becomes wide, so that the vibration of the suction reed valve can be prevented. <IMAGE>
