Abstract
A hydraulic system having a pressure generator which is protected against destructive overload. The hydraulic system has a pulsating feeding pressure generator, such as a piston pump, which feeds pressure fluid at high pressure into a damper chamber of a housing. A throttle body having a throttle bore is disposed on the outlet side of the damper chamber. For producing the protective effect, the damper chamber is preceded by a rupture disk communicating with the outlet. The throttle body suitably has a thin-walled portion, embodied as a rupture disk, in which the throttle bore is located. The embodiment described is advantageously usable in hydraulic systems in which pressure fluids are pulsatingly fed at high pressures.
