A hydrogen supply method using an inexpensive and compact hydrogen supply means to reduce a pressure of hydrogen stored in the hydrogen supply means and to supply efficiently hydrogen to a high pressure hydrogen storage means. Hydrogen is supplied under high pressure from first hydrogen supply means and from second hydrogen supply means containing a hydrogen absorbing alloy to a hydrogen storage means for storing hydrogen under high pressure. Hydrogen is supplied from the first hydrogen supply means to the hydrogen storage means until the pressure in the hydrogen storage means reaches a predetermined pressure. Thereafter, hydrogen is supplied from the second hydrogen supply means to the hydrogen storage means until the pressure in the hydrogen storage means reaches a maximum filling pressure. A plurality of the first hydrogen supply means or a plurality of the second hydrogen supply means may be used.

A gas liquid centrifugal separator includes a cylindrical vessel having an axis extending in a vertical direction, an exhaust port in a top wall of the vessel which discharges gas separated from a liquid-gas mixture, a drainage port provided in a bottom wall of the vessel which discharges liquid separated from the liquid-gas mixture, and an introducing port in a peripheral wall of the vessel which introduces the mixture into the vessel. Gas-liquid separation is conducted by an inverted conical liquid surface formed in an upper separating chamber of the vessel as a result of the mixture traveling circumferentially along an inner peripheral surface of the vessel.

Energy supplying system in which effective use of waste heat from a solar power generator and an engine power generator. Electric power generated by an SLCS (sunlight cogeneration system) 1 and an EGCS (engine cogeneration system) 2 is supplied to a power consuming apparatus while its relevant waste or exhausted heat is transferred to a heat consuming apparatus 3. The power generated by the SLCS 1 varies depending on the local climate and is monitored with a power meter 6 or a power monitor apparatus 7. When the power from the SLCS 1 is declined, it is compensated by increasing the power output of the EGCS 2. Since the total power generated by the SLCS 1 and the EGCS 2 is maintained constant and the total waste heat released from the SLCS1 and the EGCS 2 is relatively stable, the heat consuming apparatus 3 as well as an power consuming apparatus 5 are steadily energized.

A drive device for a power working vehicle has a transmission case for a hydrostatic pressure type continuously variable transmission which includes a hydraulic pump and a hydraulic motor, the case having a narrow portion and a wide portion with a step being formed on one side of the transmission case. The hydrostatic pressure type continuously variable transmission is mounted to the narrow portion, so that it is accommodated within the height of the step. A differential is provided at the wide portion for differentially operating left and right axles, and a reducing gear mechanism extends from the narrow portion to the wide portion for transmitting an output from the continuously variable transmission to the differential through a multi-stage reduction. Thus, the output from the continuously variable transmission can be transmitted to the left and right axles through a reduction at a plurality of stages, and the structure of the drive device for the power working vehicle may be made simpler and more compact.

A ball and piston valve for controlling the flow of hydraulic fluid to a motive means have the ball and piston spring biased in opposing directions and with both initially subject to a first hydraulic fluid pressure that allows the springs to cause the ball to be unseated from its seat whereby fluid is directed to a fluid tank and wherein the ball is of sufficiently larger diameter than the piston that upon an increase in fluid pressure the ball is seated and remains seated when the pressure drops to the first hydraulic fluid pressure whereby the motive means to which the fluid is directed when the ball is seated does not have a sudden lurch upon a subsequent increase in pressure.
