摘要
In the European patent application publication EP OS No. 0 102 441 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.
