The paper is focused on the description of an experimental investigation of a nozzle check valve. Attention is paid to the behaviour during transitions when the flow is decelerating. Flow reversal is often accompanied with the check valve slam, because the check valve closes with a delay after the flow changes its direction. The maximal back flow velocity determines the maximal pressure peak when the check valve closes, so this velocity was found for different flow decelerations.Článek je zaměřen na popis experimentálního výzkumu zpětného ventilu. Pozornost je věnována chování během přechodu při zpomalování proudu. Obrácení proudu je často spojeno s prásknutím zpětného ventilu, protože zavírá se zpožděním oproti změně orientace průtoku. Max...
