Patent attributes
A hydraulic device is provided herein. The hydraulic device mainly contains a reservoir having an airbag inside. The reservoir is provided with an inlet pipe and a plurality of outlet pipes, both extended from a top side of the reservoir. The inlet pipe receives water from a pumper and fills the reservoir via a back-pressure valve. The airbag expands by the air driven by an air compressor to force water from the reservoir into the outlet pipes. When the water level of the inlet pipe is higher than that of the outlet pipes, due to the siphon principle, water will continuously flows from the inlet pipe, through the vacuumed reservoir, into and then out of the outlet pipes. The water poured out of the outlet pipes can be utilized for hydroelectricity or irrigation.
