High-pressure pump having a radial piston and an attenuation layer

摘要

The invention is based on the main patent, its object being to present a further design option for reducing noise in high-pressure pumps having radial pistons. The solution, in principle, is to divide the bearing ring into an outer section (15) and an inner section (16) and to insert, between the two sections, an annular attenuation layer (damping layer) which is attached or injected there by means of a suitable adhesion method. <IMAGE>
