Abstract

Anordning ved pumpestempel (12) for resiprokerende forskyvning i en pumpesylinder (4) hvor det mellom pumpestemplet (12) og pumpesylinderen (4) er tildannet et ringrom (26) som avgrenses av en første tetning (20) og en andre tetning (24), idet ringrommet (26) er trykksatt, og hvor den første tetning (20) og den andre tetning (24) befinner seg i et felles aterialstykke som utgjør pumpestemplet (12). A device for pump piston (12) for reciprocating movement in a pump cylinder (4) for the pump piston (12) and pump cylinder (4) is formed an annular space (26) defined by a first seal (20) and a second seal (24) , the annular space (26) is pressurized, and the first seal (20) and the second seal (24) located in a common aterialstykke constitutes the pump piston (12).
