FLUID SYSTEM, IN PARTICULAR FOR USE IN A CLEANING DEVICE

The invention relates to a fluid system (110) for conducting a fluid, a nozzle system (141) comprising this fluid system (110), and a cleaning device (148) for cleaning goods (150) to be cleaned The invention also relates to a method for operating a fluid system (110) and a method for cleaning goods (150) to be cleaned. The fluid system (110) comprises at least one fluid-conducting bearing part (114) extending axially in relation to an axis of longitudinal extension (112), as well as at least one fluid-conducting rotary part (116) which is mounted on the bearing part (114) so as to be rotatable about the axis of longitudinal extension (112). The bearing part (114) and the rotary part (116) are fluidically interconnected via at least one fluid connection (118). At least one axially slidably mounted sealing element (122) is located between the bearing part (114) and the rotary part (116). The sealing element (122) annularly surrounds the bearing part (114). The sealing element (122) is located between the fluid connection (118) and at least one bearing surface (119) associated with the sealing element (122). The sealing element (122) has at least one hydraulic inner surface (124) which faces the fluid connection (118) and can be supplied with the fluid. A hydraulic force can be exerted on the sealing element in the direction of the bearing surface associated with the sealing element by applying pressure to the hydraulic inner surface (124). The sealing element (122) is in multiple parts and has at least one axially slidably mounted sliding ring (126) which surrounds the bearing part (114), and the sealing element has at least one further sealing element (128). The further sealing element (128) seals the sliding ring (126) off from at least one other component of the fluid system (110).
