Title: An improved self-driving hydraulic machine
IPC: F03G7/10
Filed: 1921-04-19
Abstract: 181,192. Amy, G. W., and Maude, H. April 19, 1921. Self-driving machines.-A self-driving hydraulic machine comprises a fixed casing a<1> and a shaft J journaled therein to which shaft various members are fixed. The various chambers of the machine are filled wih liquid, and it is stated that on pressure being transmitted to the liquid the shaft J is caused to rotate and develop more power than is put into the machine. Liquid under pressure from a rotary plunger or ram passes by means of pipes v<1>, v<2>, Fig. 3, into chambers rand thence by a port o, Fig. 1, to a chamber a. A load beam B carried by the shaft J bears part of the pressure but such pressure is balanced by means of a load on the other end B<1>, Fig. 1, of the beam B which load is obtained by means of the pressure in chamber a being transmitted by channel c<3> to chamber c<4> thence by plunger c<6> to chambers t, Fig. 3, in which chambers plungers bearing on the end B<1>, Fig. 1, operate. The pressure on the load beam B being thus balanced, the pressure is only active on the head plate d', the channel m being closed by means of one of a number of valves L which is determined by the position of the rotating centre. The pressure on the head plate d causes the various members and therefore the shaft J to rotate. The inactive liquid passes from the chamber h, Fig. 1, through the port h<1> to chambers s, thence to chambers s<1>, and by the pipe w<1> back to the plunger.
