Description

Device for generating a pulsating oil pressure "

The invention "relates to a device for generating a pulsating Oil pressure of high frequency, especially for the drive of the Schwingtisehea

There are known pulsators for hydraulic material testing machines, where a pulsating oil pressure through a reciprocating Piston is produced «With such pulsators can only be relatively achieve low frequencies. But ss is often desirable, pulsating Generate high oil pressures, for example for material testing machines or to drive Schwingt !, that is with the well-known Pulsators are limited by the fragility of the system.
