Throttle device, fluid device and fluid system

A throttle device, comprising:

• a throttle member which is arranged on a holding structure and projects into a throttle channel through which a pressurized fluid can flow and which can be moved relative to the holding structure in order to specify differently sized free flow cross-sections of the throttle channel,
• wherein the throttle member is designed as a throttle tongue which is attached to the holding structure with a proximal end section and which, starting from the proximal end section, projects into the throttle channel with a distal end section ending freely and divides same into two throttle channel sections following one another in a channel longitudinal direction,
• wherein the throttle tongue can be pivoted into various pivot positions depending on the pressure difference prevailing between the two throttle channel sections, starting from a neutral position adopted in a pressure-balanced state between the two throttle channel sections, while changing the free flow cross-section of the throttle channel with accompanying rubber-elastic reversible deformation in the direction of the one or other of the two throttle channel sections.
