ABSTRACT:
A pressure source for providing a stream of liquid at a substantial pressure. The pressure source includes pressurizing means such as a piston-cylinder assembly to which a force is applied to expel the contents thereof under pressure to form the stream. Weight means moving from an upper elevation to a lower elevation provides the said force. The pressure source also includes means to release, in discrete quantums of mass, the weight means for downward movement, in the preferred embodiments, without substantial impediment other than the pressurizing means. This provides sufficient force to supply a stream at a usefully high pressure, for example one which can drive a turbine wheel or a linear actuator at a useful velocity. In a preferred form, the weight means is a buoyant body, and the pressure source includes lift means to float the buoyant body to the upper elevation, and then to permit it to descend to the lower elevation. Systems which can utilize this power source include rotary shaft drives such as turbines, linear shaft drives (linear actuators), and rotary devices driven by linear drives through unidirectional transmission elements (one-way clutches). The systems may also include driven elements such as electrical generators.
