    • To provide an efficient piston pump having a small number of parts and simple assembly steps, and consuming less current in achieving a relatively low ultimate pressure. The piston pump comprises: a suction port (28) through which gas sucked by varying the volume of a pump chamber (22) defined by a cylinder (12) and a piston (14) fitted in the cylinder (12) passes as the piston (14) is reciprocated, an exhaust port (20) through which the gas discharged by varying the volume of the pump chamber (22) passes, a suction valve (26) installed in the suction port (28) disposed on a piston top, and an exhaust valve (18) installed in the exhaust port (20) disposed on a top of the cylinder (12).
    • 提供一种具有少量部件和简单组装步骤的高效活塞泵,并且在实现相对低的极限压力时消耗更少的电流。 活塞泵包括:吸入口(28),通过改变由气缸(12)限定的泵室(22)的体积和安装在气缸(12)中的活塞(14))吸入的气体通过该吸入口作为活塞 (14)往复运动,排气口(20)通过改变泵室(22)的体积而排出的气体通过,安装在设置在活塞顶部上的吸入口(28)中的吸入阀(26) 以及安装在设置在所述气缸(12)的顶部上的排气口(20)中的排气门(18)。
