Abstract
Hydraulic pressure booster and method includes a low-pressure segment including a hydraulic cylinder and a hydraulic piston, which is displaceable in both axial directions of the hydraulic cylinder and opposing high-pressure segments located on each axial end of the low pressure segment. Each high-pressure segment includes a plunger piston movable in a high-pressure cylinder via the hydraulic piston. Each high-pressure cylinder is arranged in a clamping sleeve, both of which are positioned between the hydraulic cylinder and a valve body. For each high-pressure segment, a clamping piston, which includes a pressure surface applying pressure to the high pressure cylinder and a high pressure seal for the plunger piston and a pressure surface on which pressure from the hydraulic piston is applied, is axially displaceable in the hydraulic cylinder so that the high-pressure cylinder is in compressive contact with the hydraulic cylinder and the valve body.
