DEVICE AND METHOD FOR CONTROLLED SUPPLY OF HIGH-PRESSURE FLUID
The invention relates to a device for controlled supply of high-pressure fluid. In order to minimise the disadvantages of the prior art with regard to a complicated structure, notable wear and complex controllability at low speed and to achieve economically viable operation, according to the invention the pressure generator (D) in each case comprises an electric linear motor (L) having a stator (9) and a forcer (10) to drive the high-pressure plunger (17) in the high-pressure cylinder (15), and the electric linear motor(s) (L, L') is (are) connected to an electric control unit (12).

Hydraulic pressure booster and method for the production of an axial compressive stress in a high-pressure cylinder
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.

Cylinder unit of a high pressure pump for a fluid. Cylinder unit includes a cylinder formed by at least two concentric tubular components coupled by a shrink connection. A flange part with sealing system is detachably connected on one side of the cylinder, and sealing system has a movable plunger and a bearing bushing. A valve body is connected on other side of the cylinder. Bearing bushing and radially outermost component are arranged to bear against flange part to form an intermediate gap, a spring device has a distal portion supported on outermost component of the cylinder and a proximal portion on an outside of bearing bushing, and a valve body against which an other side of the cylinder bears are included. The tubular components have a metallic connection in a region of a surface bearing between the valve body and the cylinder.
