Abstract: The invention relates to a diaphragm pump (109) having a pump housing (1) on which a disposable cell (2) is releasably fixable, which disposable cell has a first and a second cell wall (3, 4) which (3, 4) define an operating space (5) between them, and having an operating diaphragm (6) which (6) is drivingly connected to an oscillating stroke drive and which (6) is releasably coupleable with the flexible first cell wall (3) on its diaphragm flat side remote from the stroke drive. It is characteristic to the diaphragm pump (109) according to the invention that at least one outlet port (12) in the operating diaphragm (6) is provided with a return flow obstructer or a return flow preventer for evacuating the dead space (11) arranged between it and the first cell wall (3) (cf. FIG. 1).
Abstract translation: 本发明涉及一种具有泵壳体（1）的隔膜泵（109），一次性电池（2）可释放地固定在该壳体上，该一次性电池具有第一和第二电池壁（3,4），其中3,4 ）在它们之间限定操作空间（5），并且具有操作隔膜（6），其中（6）驱动地连接到振荡冲程驱动器，以及（6）可释放地与其上的柔性第一电池壁（3）耦合 隔膜平面远离行程驱动。 根据本发明的隔膜泵（109）的特征在于，操作隔膜（6）中的至少一个出口（12）设置有用于抽空死空间（11）的回流阻塞器或回流防止器， 布置在它和第一细胞壁（3）之间（参见图1）。

Abstract: A plate or check valve, for diaphragm pumps, including a valve chamber in which at least one valve seat is provided that interacts with a valve plate that is elastically pretensioned via outer edge mountings such that a closing body of the valve plate can be moved from a closed position, in which it sealingly lies on the valve seat, into an open position against the elasticity of the valve plate. The outer edge mountings have webs and connecting brackets which are connected to the web ends facing away from the closing body. The outer edge mountings are disconnected from one another and only engage on the closing body, each of the outer edge mountings has at least two webs that are connected together via a connecting bracket, and each connecting bracket engages behind at least one paired holding base of the valve housing.
