  • This control is formed in a specific embodiment as a membrane. The membrane is acted upon by a control chamber into which a branch of the vent line opens. Therefore, if an overpressure prevails in the ventilation line, the overpressure present in the control chamber pushes the membrane against the valve body and lifts it off the seat, so that the ventilation line can be vented to the environment.

Since the required pressure difference for a sufficient volume flow in the order of 50 1 / h only has to be about 50 mbar, a diameter similar to the control element (the diaphragm) of this valve unit can be selected for the radial pump, so that the integration of the pump function leads to a very cheap design.
