Japanese Patent JPH0225045
Kind Code:
B2
Abstract:
The invention relates to a pressure averager for providing an averaged working pressure from the operating pressures of at least two sources of pressure medium, there being provided to average the operating pressures a differential piston of which the number of step faces which face the same direction and which are of equal size corresponds to the number of operating pressures to be averaged, of which the oppositely directed working face is equal to the sum of the step faces, and which is displaceably guided in a correspondingly stepped housing which is provided with supply lines for the operating pressures, and its object is to develop the pressure averager in such a way that an additional pressure relief valve is not required for its function within a hydraulic installation. This is achieved in that annular grooves in each case associated with a control edge of the respective step faces are provided in the housing, and in that leading away from the annular grooves there are discharge lines which are connected to a common line for the averaged pressure which is connected in turn to the working face.
