leengedése

Leengedése is a noun in Hungarian that denotes the act or process of letting something down, lowering its height or level, or releasing contents or pressure from a vessel or system. It derives from the verb leengedni, where le- conveys downward movement and -dni marks the infinitive; the suffix -és forms the noun.

The term is used across several contexts. In mechanical and structural settings, leengedése can refer to lowering a load, descending a scaffold, or lowering a component to a desired position. In fluid and gas handling, it covers draining or venting liquids or gases from containers or pipelines, as well as depressurizing a system through drains or valves. In water management and civil engineering, leengedése describes lowering water levels in reservoirs, canals, or flood-control structures, either as routine operation or in response to changing conditions. In industrial maintenance, it may refer to draining fluids from machinery for servicing or flushing lines as part of safety and maintenance procedures.

Context often determines the emphasis of the term: it can describe a state (the contents have been released or the level has been reduced) or an action (the procedure of lowering or draining). While the specific method can vary—manual lowering, mechanical systems, or controlled drainage—the core idea is the reduction of height, level, or contained content, or the release of pressure.
