tlakovým

Tlakovým is the instrumental singular form of the Czech adjective tlakový, meaning "pressure-related" or "pressurized." It is used to denote the means, method, or instrument by which an action is performed or to describe equipment and systems that operate under pressure. The masculine/neuter instrumental singular is tlakovým, the feminine instrumental singular is tlakovou, and the plural instrumental is tlakovými. Tlakovým typically occurs with masculine or neuter nouns in the instrumental case, as in tlakovým vzduchem (by compressed air) or tlakovým médiem (by pressurized medium).

Etymology and usage context: The word derives from the noun tlak (pressure) with the adjectival suffix -ový. It is common in technical, engineering, and scientific language to express that a device, substance, or process relies on pressure. The form tlakovým specifically marks the means or agent in constructions such as “přístroj pracuje tlakovým vzduchem.”

Usage notes: Tlakový and its forms are used across fields like hydraulics, pneumatics, and materials science to describe systems, tools, or processes driven by pressure. In many phrases, the two-word combination tlakový + noun is used, while tlakovým serves as the instrumental form when the sentence requires a means or instrument.

Examples:

- Systém pracuje tlakovým vzduchem.

- Nádrž je naplněna tlakovým médiem.

- Tlakovým ventilem se reguluje průtok.
