Vacuum Cleaning Tool, Especially Hand-Held Nozzle, for a Vacuum Cleaner
First Claim
1. A vacuum cleaning tool for a vacuum cleaning device, the vacuum cleaning tool comprising:
- a housing having a working chamber at a first end and a connecting socket, adapted to receive a vacuum hose, at a second, opposed end;
a brush roller arranged in the working chamber;
wherein the housing has a turbine chamber arranged between the working chamber and the connecting socket;
an air turbine arranged in the turbine chamber;
wherein the working chamber extends transversely to a longitudinal axis of the vacuum cleaning tool;
wherein the working chamber has a bottom provided with at least one vacuum air port through which a vacuum air flow enters the working chamber;
wherein the housing has a connecting opening between the working chamber and the turbine chamber and a discharge opening between the turbine chamber and the connecting socket, wherein the vacuum air flow passes from the working chamber into the turbine chamber and drives the air turbine, wherein the vacuum air flow passes from the turbine chamber through the discharge opening into the connecting socket;
wherein bristles of the brush roller act through the at least one vacuum air port on a surface to be treated;
wherein the air turbine has a base member;
a support shaft mounted in the housing;
a bushing on which the base member of the air turbine is fixedly mounted, wherein the bushing is rotatably supported on the support shaft.

Abstract
A vacuum cleaning tool has a housing with a working chamber and a connecting socket for a vacuum hose. A brush roller is arranged in the working chamber. An air turbine is arranged in a turbine chamber between working chamber and connecting socket. The working chamber has a bottom with vacuum air ports through which a vacuum air flow enters the working chamber. The housing has an opening between working chamber and turbine chamber and a discharge opening between turbine chamber and connecting socket. The vacuum air flow passes from the working chamber into the turbine chamber and drives the air turbine and then passes through the discharge opening into the connecting socket. The brush roller acts through the vacuum air ports on a surface to be treated. A bushing on which the air turbine is fixedly mounted is rotatably supported on a support shaft mounted in the housing.
