    • PURPOSE: A piston pump is provided to simplify the mounting structure of a closed body and enhance the closing and opening characteristics of an intake valve. CONSTITUTION: A piston pump(10) comprises a piston(16), a sealing member(48), and an intake valve(18). The sealing member seals the piston to a cylinder(14) in a radial direction. The intake valve is arranged on the piston and comprises a closed body(51). The closed body is supported by a spring member. The spring member is formed integrally with the sealing member. The spring member comprises a first section and a second section. The first section is extended from the sealing member and is aligned in an axial direction. The second section is connected to the first section and is aligned in a radial direction.
    • 目的:提供活塞泵,以简化封闭体的安装结构,提高进气阀的关闭和开启特性。 构成:活塞泵(10)包括活塞(16),密封件(48)和进气阀(18)。 密封构件在径向上将活塞密封到气缸(14)。 进气阀布置在活塞上并包括一个封闭体(51)。 封闭体由弹簧构件支撑。 弹簧构件与密封构件一体地形成。 弹簧构件包括第一部分和第二部分。 第一部分从密封件延伸并沿轴向对准。 第二部分连接到第一部分并且沿径向对齐。
