Embodiment Construction
[0023] exist figure 1 In , the pressure chamber device as a whole is denoted by reference numeral 1 . The device 1 comprises a pressure chamber 2 , which in this case is formed by a pressure vessel, and has an opening, which can be closed by a cover 3 , for mounting an electric motor 7 with a pump 9 in the pressure vessel. There is also a pipe system 5 with an inlet 5a and an outlet 5b. The electric motor 7 is placed in the pressure chamber 2 . The pump 9 is mounted on the output shaft 8 of the motor 7 . The pump 9 , for example formed by a centrifugal pump with impellers, is in this case mounted directly on the motor shaft 8 . The pump 9 is housed in a pump housing 10 including an inlet 11 and an outlet 12 . The outlet 12 is connected to the outflow port 5b.
[0024] The shown pressure chamber arrangement can be used in a high-voltage circuit as a second pressure chamber in combination with a first pressure chamber for processing substrates.
[0025] Motor 7, which is i...
