摘要：
In the European patent application publication EP OS O No. 102 441 a high pressure pump is shown which uses tapered rings (disc spring derivatives) which are clamped together as a pump chamber. The clamping rings required cutting into sections which is expensive and time consuming. The present discoverings now show that the friction at compression of the coned rings was very large. The present invention now discovers that radially flexible ring portions should be provided to the coned ring portions in order to eliminate the friction and to reduce the time and cost of the production of the pump arrangement. The invention further provides U-type pump elements which eliminate the clamping rings. A second pressure led into the space in the housing which surrounds the pump elements makes it possible to increase the pressure in the pump, for example, to double the pressure.
