  • System separator
    Patent number: 10544570
    Abstract: A pressure reducer for a system separator includes a seal element accommodated in a groove, which is subject on a first side to a pressure prevailing at an inlet-side connection stub of the system separator and on a second side to a pressure prevailing in an inlet chamber of the system separator. At least one recess is introduced into a wall delimiting the groove on the first side, into which recess the seal element partially enters, canceling out its sealing effect, when the pressure prevailing at the inlet-side connection stub falls below the pressure prevailing in the inlet chamber.
