  1. PŘEDMĚT VYNÁLEZU
    1. Výtlačný prvek se šikmou uzavírací hranou pro odpojeníválce ve vstřikovacích čerpadlech vznětových motorů, u nichž jsou všechny písty otočné o jeden a tentýž úhela jejichž šikmá uzavírací hrana má rovnoměrný sklon a provýtlačné prvky, které jsou odpojované v režimu běhu na-prázdno a při nízkém zatíženi, je vytvořena dozadu odvede-ná plocha malé hloubky, vytvářející škrtící štěrbinu s ma- nlým příčným průřezem, vyznačující se tím, že dozadu odvede-ná plocha (60) je umístěná paralelně s vratnou drážkou (5),procházející rovnoběžně s osou pístu, přičemž vzdálenost(51) mezi plochou (60) a vratnou drážkou (5) je menší nežprůměr propouštěcího otvoru (4).
  2. 2. Výtlačný prvek podle bodu 1, vyznačující se tím, že horníhrana dozadu odvedené plochy (60) je od horní hrany (7)pístu (1) oddálena o vzdálenost (71).
  3. 3. Výtlačný prvek podle bodu 1, vyznačující-'se'· tím, že dozaduodvedená plocha (60) má vytvořeno vnitřní ohraničení (8),které(svírá s osou pístu (l) ostřejší úhel než šikmá uzavírací hrana (3).
