Abstract (en)

[origin: DE10125420C1] The interconnecting transfer channel (19) opens into bores (26, 27) forming passages. The sealing disk or membrane closure (28) of the transfer non-return valve (20) is loosely-guided and restricted in its stroke. The bores have different diameters and are arranged in a common partial circuit, being spaced radially from the closure membrane axis. They are completely covered by it.
