    • A diaphragm pump (10) including a body (11) that provides a pair of opposed pump chambers (12) and (13). Mounted in the body (11I) is a piston assembly (14) providing a pair of pistons (15) joined by a transverse piston rod (16) so that the pistons (15) are caused to reciprocate in unison linearly in the direction (17) along the axis (18). Each piston (15) includes a diaphragm (22) that provides a first sub-chamber (23) and a second sub-chamber (24). A working fluid (liquid or gas) under pressure is alternately delivered to the sub-chambers (23) to cause the piston assembly (14) to reciprocate. A valve (25) is operated to co-ordinate delivery of the fluid under pressure or alternately to the first sub-chambers (23).
    • 一种隔膜泵(10),包括提供一对相对的泵室(12)和(13)的主体(11)。 安装在本体(11I)中的是活塞组件(14),其提供由横向活塞杆(16)连接的一对活塞(15),使得活塞(15)沿着方向(17)线性地一致地往复运动 )沿轴线(18)。 每个活塞(15)包括提供第一子室(23)和第二子室(24)的隔膜(22)。 在压力下的工作流体(液体或气体)交替地传送到子室(23)以使活塞组件(14)往复运动。 操作阀(25)以协调压力下的流体输送或交替地与第一子室(23)的输送。
