    摘要： In a fuel pump that includes a pump housing (10) that has fuel passages (11a, 11b), a plunger (17) that is movably housed in the pump housing (10), a fuel pressurizing chamber (15) that is formed in the pump housing (10) and draws in fuel via one of the fuel passages (11a) that is on the intake side of the fuel pressurizing chamber (15), pressurizes the fuel that has been drawn in, and discharges the pressurized fuel via the other fuel passage (11b) that is on the discharge side of the fuel pressure chamber (15), in response to movement of the plunger (17), and valve elements (12, 14, 16) that are arranged in the fuel passages (11a, 11b) near the fuel pressurizing chamber (15), each of the valve elements (12, 14, 16) has a reed valve body (41, 42, 43; 74, 75, 76) arranged in the fuel passage (11a) on the intake side of the fuel pressurizing chamber (15) or the fuel passage (11b) on the discharge side of the fuel pressurizing chamber (15); and an operating member (21) that applies operating force in at least one of a valve opening direction or a valve closing direction to the reed valve body (41, 42, 43; 74, 75, 76) is provided in the pump housing (10).

    摘要： Disclosed is a valve plate, comprising: a mounting column (11); a plurality of blades (12) distributed outside the mounting column (11), along the circumference thereof. The radially inner end of each blade (12) is connected to the mounting column (11) and swings elastically relative to the mounting column (11). Adjacent blades (12) are separated by a rib (13), one end of the rib (13) being connected to the mounting column (11). The position on the blade (12) where the blade is connected to the rib (13) is provided with a buffer structure, the buffer structure being used to provide a deformation buffer space for the blade (12). Also disclosed is an air pump provided with the present valve plate. The present valve plate effectively reduces airflow noise, thus achieving the aim of reducing air pump noise.

    摘要翻译： 公开了一种阀板，包括：安装柱（11）; 分布在安装柱（11）的外侧的多个叶片（12）。 每个叶片（12）的径向内端连接到安装柱（11）并相对于安装柱（11）弹性摆动。 相邻的叶片（12）由肋（13）分开，肋（13）的一端连接到安装柱（11）。 叶片（12）上与叶片（13）连接的位置设置有缓冲结构，缓冲结构用于为叶片（12）提供变形缓冲空间。 还公开了一种设置有本阀板的气泵。 本阀板有效降低气流噪音，达到减少气泵噪音的目的。
