Abstract: A vehicle hydraulic fluid system includes an engine driven pump which excites the fluid in the system downstream of the pump by imparting pressure pulses thereto at frequencies which vary as the speed of the engine, and hence, the pump varies. For the purpose of inhibiting the transmission of these pulses through the system and thereby lessening noise caused by the radiation of the pulses by components in the system, a cross loop attenuator is coupled in the system adjacent the pump outlet. The attenuator comprises a simple hose or tube having its opposite ends coupled to opposite sides of a cross fitting having its other two sides coupled in a line leading from the pump outlet.
