1. Med tryckmedium driven apparat, som alstrar fram och äter händande rörelse för en eller flera kolvar (14,15) eller motsva-rande skaft, son överför rörelse, vilken apparat omfattar i ett kapslat utrymme en primärkolv (3) som rör sig fram och äter en-bart med hjälp av tryckmedium och i vilken apparat tryckmediums styrningsventiler (8,9) som häller i rörelse primärkolven (3) ligger inne i sagda primärkolv, kännetecknadav, att det finns i apparaten för styrning av ovannämnda fram och äter händande rörelse en egen sätesventil (8), (9) för bäda rörelse-riktningarna, i vilken den rörande delen (8), (9) omfattar en ringformig kompresserande ändyta (24), (25), pä vilken trycket vid öppnandet av sagda ventiler omedelbart verkar och förstärker kraft som öppnar ventiler (8,9).
2. En apparat enligt patentkrav 1 kännetecknad av, att i primärkolven (3) ligger en strömningskanal (13), genom vilken en stigning och/eller sänkning i trycket av medium ästad-kommer stängandet och öppnandet av sätesventiler (8,9).
3. En apparat enligt patentkrav 1 eller 2 kännetecknad av, att i primärkolven (3) liggande kanalen, som rör sig med avseende pä stammen (2), har i stammen (2) en avstängnings-organ (26), vars längd bestämmer primärkolvens fram och äter händande rörelselängd.
4. En apparat enligt patentkrav 3 kännetecknad av, att organet (26) som stänger och öppnar kanalen (13) är cylin-derhusets (2) inneryta.
5. Med tryckmedium driven pump, som omfattar ett cylindriskt pumphus (2), en eller flera fram och äter rörande pumpkolvar (14), (15), en motsvarande cylinder (1) för varje kolv för att pumpa vätska eller gas, och inne i stammen (2) en primärkolv (3), kopplad tili en pumpkolv (14,15) kännetecknad av, att primärkolven (3) omfattar för drivande tryckmedium ventiler (8,9) för att styra tryckmedium tili bäda sidorna av primärkolven, en strömningskanal (13) som styr ventilers (8,9) 8 96132 verksamhet och ett strömningskanalen (13) avstängande organ (26), som reglerar slaglängd av primärkolven.
6. En pump enligt patentkrav 5 kännetecknad av, att det finns tvä pumpkolvar (14,15) emot varandra, primärkolven (3) drivs med trycket av hydraulisk vätska, och att ventilerna (8,9) är tryckstyrda sätesventiler. i « il
