Abstract (en)
[origin: US5299916A] The present invention relates to a liquid-ring pump which effectively dampens noise by providing a blocking element arranged in its compression space in the flow path between the mouth of its output port and the outlet opening of its discharge connection. The blocking element covers this outlet opening and has a flow-through opening. The cross-section of the flow-through opening automatically adapts to the quantity of medium delivered by the pump at any given time.
