Description

Patentkrav 1. Trykforstærker til væsker, særlig hydraulikvæsker, med et forstærkerstempel omfattende et højtryksstempel og et lavtryksstempel med forstørret diameter, hvorved forstærkerstemplet er bevægeligt sammen med højtryksstemplet i en højtrykscylinder og sammen med lavtryksstemplet i en lavtrykscylinder, hvorved højtrykscylinderen kan forbindes med en højtrykstilslutning og lavtrykscylinderen, via en styreventil, kan forbindes med en forsyningstilslutning, når styreventilen er i en første skifteposition, og med en tilbageløbstilslutning, når styreventilen er i en anden skifteposition, og styreventilens skiftepositioner styres af forstærkerstemplets stilling, der frigiver eller blokerer en forbindelse mellem en første styreledning, der er forbundet med forsyningstilslutningen eller en anden styreledning, der er forbundet med styreventilen, kendetegnet ved, at forbindelsen (28) er anbragt fuldstændig indenfor højtryksstemplets (11) bevægelsesslag. 2. Trykforstærker i henhold til krav 1, kendetegnet ved, at de to styreledninger (24, 29) udmunder i højtrykscylinderens (10) væg i et område, der, uafhængigt af forstærkerstemplets (27) stilling, ligger udenfor et højtrykskammer (9), der begrænses af højtrykscylinderen (10) og højtryksstemplet (11) . 3. Trykforstærker i henhold til krav 2, kendetegnet ved, at højtryksstemplet {11) har en udsparing (28), der i en forud fastlagt forstærkerstempelstilling (27) dækker mundingerne på begge styreledninger (24, 29). 4. Trykforstærker i henhold til krav 3, kendetegnet ved, at udsparingen (28) er udformet som et ringformet kammer, 5. Trykforstærker i henhold til krav 3 eller 4, kendetegnet ved, at der mellem udsparingen (28) og højtrykskammeret er anbragt en tætningsanordning (32) med en lækageafløbsledning (33). 6. Trykforstærker i henhold til et af kravene 1 til 5, kendetegnet ved, at styreventilen (15) er forbundet med returløbstilslutningen (3) via en forbindelse (20, 22), der er ført gennem lavtrykscylinderen (14) i et område mellem højtryksstemplet (11) og lavtryksstemplet {12) . 7. Trykforstærker i henhold til et af kravene 1 til 6, kendetegnet ved, at lavtryksstemplet (12) på periferien af mindst en forside har en omløbende udsparing (18) og en tilhørende forbindelse (17) mellem styreventilen (15) og lavtrykscylinderen (14) udmunder i endevæggen (19) på lavtrykscylinderens (14) omfangs-væg. 8. Trykforstærker i henhold til et af kravene 1 til 7, kendetegnet ved, at en droslet hjælpestyringsforbindelse (31) er anbragt mellem forsyningstilslutningen (2) og en styretilslutning (30) på styreventilen (15), der omkobler styreventilen (15) til den første skifteposition. 9. Trykforstærker i henhold til krav 8, kendetegnet ved, at hjælpestyringsforbindelsen (31) er anbragt i et ventilelement (16) på styreventilen (15).
