Embodiment Construction
[0253] Figures 1a to 1c A check valve configuration 1 in a first exemplary embodiment of a functional device according to the invention is shown.
[0254] Figure 1a Valve construction 1 shown in exploded view, Figure 1b is in the first position, i.e., the inactive open initial position, and Figure 1c is in the second position, ie, the "residual" (ie, "continuous" or "permanent") enabled check valve position.
[0255] The one-piece valve body 30 is composed of silicone rubber. The centrally located cylinder or section of the valve body 30 (referred to herein as the core cylinder 31 ) through its front end facing the membrane provides for the axial activation projections to be introduced on the cassette membrane and the activation of the machine. Actuators (also referred to simply as actuators, are not shown or illustrated here, but can be found in Figure 6f ) acts as a sufficiently rigid transmission element. The radial sealing strip 32 , for example cup-shaped, is pe...
