Rotational hydraulic transformer

Abstract

A rotational hydraulic transformer for boosting system pressure of a hydraulic system, which is continuous, compact and has little pulsation, comprises: a first volume increasing/decreasing mechanism Y1 for cyclically and continuously increasing/decreasing the volume of a plurality of first annularly arranged spaces 8, by shifting the phase of each, by means of employing relative positional change of two relative moving members 1 and 3; a second volume increasing/decreasing mechanism Y2 for cyclically and continuously increasing/decreasing the volume of a plurality of second annularly arranged spaces, by shifting the phase of each, the second volume increasing/decreasing mechanism Y2 sharing the two relative moving members 1 and 3, and performing the increasing/decreasing by means of employing relative positional change of the two relative moving members; a pair of first channels A01 and A02, wherein one channel is connected to said first spaces of which the volume is increasing while the other channel is connected to said first spaces of which the volume is decreasing; and a pair of second channels B01 and B02, wherein one channel is connected to said second spaces of which the volume is increasing while the other channel is connected to said second spaces of which the volume is decreasing; wherein the increasing/decreasing volume of the first spaces 8 in one cycle is made to be different from that of the second spaces 9 in one cycle.
