Abstract

A pressure intensifier for pressurization of a medium is provided, comprising a low-pressure cylinder (1), in which a low-pressure piston (2) is axially displaceable, and two high-pressure chambers (3, 4) which are each arranged coaxially with and on separate sides of the low-pressure cylinder (1) and which each exhibit an axially displaceable high-pressure piston (9, 10) which are secured to the low-pressure piston (2). A channel (16), provided with a nonreturn valve (17), connects the two high-pressure chambers. The area of one high-pressure piston (9) may be larger than the area of the other high-pressure piston (10).
