Pulsation damper element for a fluid pump and associated fluid pump

用于流体泵的脉动缓冲元件及相应的流体泵

Abstract

The invention relates to a pulsation damper element for a fluid pump and associated fluid pump. The pulsation damper element for the fluid pump with an elastic diaphragm and a fluid pump having such a pulsation damper element is disclosed. A pot-shaped diaphragm carrier with an elastic region is provided, the elastic diaphragm being introduced, fluid-tight, into the diaphragm carrier such that latitude of movement of the elastic diaphragm in the pressure direction is limited by the movable region of the diaphragm carrier.
本发明涉及用于流体泵的脉动缓冲元件及相应的流体泵。本发明提出了一种用于流体泵的具有弹性隔膜(20,20’)的脉动缓冲元件(1)以及一种具有这种脉动缓冲元件(1)的流体泵。根据本发明,盆形的隔膜支撑件(10)具有弹性的区域(14),其中,弹性隔膜(20,20′)流体密封地嵌入隔膜支撑件(10)中,使得弹性隔膜(20,20′)的运动间隙(D1)沿压力方向(P)被隔膜支撑件(10)的可移动的区域(14)限定。
