<p>PURPOSE: To further reduce the generation of vibration and noise due to opening and closing of a delivery valve and to improve the volumetric efficiency of a device, such as a compressor. CONSTITUTION: The contact surface 32 of a valve plate 30 with a delivery valve 28 during closing of the delivery valve 28 is formed in an inclination recessed part which is gradually curved in a direction in which it gradually approaches the cylinder side from the mounting part 35 side of the delivery valve 28 on the valve plate 30 toward the tip side of the delivery valve 28. The contact surface 33 of a retainer 31 on the delivery valve is formed on an up curved surface curved in a direction in which it is gradually spaced away from the valve plate 30 from the mounting part 35 side of the delivery valve 28 to the valve plate 30 toward the tip side of the delivery valve 28. The starting point A of the curve of the inclination recessed part 32 of the valve plate 30 is positioned further near the mounting part 35 side of the delivery valve 28 on the valve plate 30 than the starting point B of the curve of the up curved surface 33 of the retainer 31.</p> |
