    • An air pump comprising a piston located inside a piston housing having a crown and an open end. The piston is provided with a pressure generating member in the form of a resilient membrane-like annular disc which is held centrally on one end of the piston, which is fitted in the piston housing with the annular disc and the piston plate pointed towards the crown of the piston housing whereby the rim of the membrane-like annular disc bears against the inner wall of the piston housing and the piston housing is guided on the piston in a manner enabling it to be moved axially.
    • 一种空气泵,包括位于具有冠部和开口端的活塞壳体内的活塞。 活塞设置有弹性膜状环形盘形式的压力产生构件,该环形盘被中心地保持在活塞的一端上,活塞壳体与环形盘装配在活塞壳体中,活塞板指向冠部 ,由此膜状环形盘的边缘抵靠活塞壳体的内壁,并且活塞壳体以能够轴向移动的方式在活塞上被引导。
