ABSTRACT:
A throttle in a hydraulic system having a cross section which varies as a function of fluid flow in the hydraulic system. A throttle restriction includes a bore with a wire end segment extending in the bore that reduces the cross section of the bore. The wire end segment has an end face, facing counter to the pressure fluid flow, on which flow forces are operative. The flow forces are capable of positively displacing the wire end segment out of the bore counter to a spring restoring force. The throttle can for instance be used in the hydraulic brake systems in which peaks in volumetric flow and pressure are to be reduced. The throttle can also be used wherever self-cleaning of the throttle restriction is desired.
