Fluid seal arrangement and method for constricting a leakage flow through a leakage gap

The invention refers to a fluid seal arrangement for constricting a leakage flow (8) directed through a leakage gap (18) bordered by a rotational and a stationary component (16, 17) comprising at least one nozzle opening (13) in the rotating and/or stationary component (16, 17) facing towards the ro...

More Information
Summary:The invention refers to a fluid seal arrangement for constricting a leakage flow (8) directed through a leakage gap (18) bordered by a rotational and a stationary component (16, 17) comprising at least one nozzle opening (13) in the rotating and/or stationary component (16, 17) facing towards the rotating or stationary component (16, 17) of an opposite side of the leakage gap (18) respectively in order for injecting a liquid or gaseous fluid flow (14) through the nozzle opening (13) into the leakage gap (18). The invention is characterized in that said at least one nozzle opening (13) is fluidly connected to a cooling channel (11) inside said rotating and/or stationary component (16, 17), so that said fluid flow emanating at the nozzle opening (13) consists of a cooling fluid of the rotating and/or stationary component (16, 17) exclusively.
