Gas supply apparatus
A gas supply apparatus with a shaft, which is rotatably mounted about a rotational axis in a housing, and with a temperature-controlling device, which consists of a medium temperature control surrounding the shaft, which is combined with a gas temperature control. The temperature-controlling device comprises a temperature-controlling sleeve with a first temperature-controlling guide geometry, which opens radially outward and is designed for guiding the flow of a temperature-controlling medium, and, for temperature-controlling gas, a gas temperature-controlling ring, which is equipped with a second temperature-controlling guide geometry that opens radially outward, and which delimits the first temperature-controlling guide geometry inwardly and/or axially and is delimited radially outwardly by a housing body, wherein the gas temperature-controlling ring comprises a sleeve-like base body, which is combined with a structural sheet metal that serves as the second radially outwardly opening temperature-controlling guide geometry.
1 . A gas supply apparatus comprising:
a shaft, which is rotatably mounted about a rotational axis;
a temperature-controlling device including a medium temperature control surrounding the shaft and combined with a gas temperature control; and
a housing, wherein the housing is configured to surround the shaft and the temperature-controlling device wherein the temperature-controlling device comprises:
a temperature-controlling sleeve with a first temperature-controlling guide geometry, which opens radially outward and is configured for guiding a flow of a temperature-controlling medium, and, for temperature-controlling gas,
a gas temperature-controlling ring, which includes a second temperature-controlling guide geometry that opens radially outward, said gas temperature-controlling ring delimiting the first temperature-controlling guide geometry inwardly and/or axially and being delimited radially outwardly by a housing body, wherein
the gas temperature-controlling ring comprises a sleeve-like base body, which is combined with a structural sheet metal that serves as a second radially-outwardly opening temperature-controlling guide geometry, and
the housing radially outwardly delimits the second temperature-controlling guide geometry of the gas temperature-controlling ring and at least partially delimits the first temperature-controlling guide geometry of the temperature-controlling sleeve.
2 . The gas supply apparatus according to claim 1 , wherein the sleeve-like base body is configured as a straight circular-cylindrical barrel.
3 . The gas supply apparatus according to claim 1 , wherein the sleeve-like base body comprises a collar at one end.
4 . The gas supply apparatus according to claim 1 , wherein the structural sheet metal is connected to the sleeve-like base body in a material-locking manner.
5 . The gas supply apparatus according to claim 1 , wherein the structural sheet metal is connected to the sleeve-like base body in a positive-locking manner.
6 . The gas supply apparatus according to claim 1 , wherein, on a side facing away from the sleeve-like base body, the structural sheet metal comprises a gas-guiding surface with raised regions, which serve as the second radially-outwardly opening temperature-controlling guide geometry.
7 . A method for manufacturing a temperature-controlling device for a gas supply apparatus according to claim 6 , wherein a sheet metal material is reshaped to form the gas-guiding surface with the raised regions, which serve as the second radially-outwardly opening temperature-controlling guide geometry.
8 . The method according to claim 7 , wherein the reshaped sheet metal material is bent and merged at two ends to create a structural sheet metal sleeve that is connected to the sleeve-like base body to realize the gas temperature-controlling ring, which is mounted on the temperature-controlling sleeve.
9 . The method according to claim 7 , wherein the reshaped sheet metal material is bent around the sleeve-like base body and connected thereto to define the gas temperature-controlling ring.
10 . A gas supply system comprising:
a shaft rotatably mounted about a rotational axis in a housing; and
a temperature-controlling device including a medium temperature control surrounding the shaft and combined with a gas temperature control, wherein the gas temperature control comprises a gas temperature-controlling ring comprising:
a sleeve-like base body configured as a straight circular barrel;
a collar at one axial end of the base body, wherein the collar has a receptacle groove for receiving a sealing element;
a structural sheet metal configured as a second radially-outwardly opening temperature-controlling guide geometry; and
a separator configured to connect end portions of the structural sheet metal, wherein the separator separates an inflow recess from an outflow recess.
