Abstract: An apparatus for generating a mixture of oxygen gas and hydrogen gas is provided with an electrolytic cell in which electrolysis of electrolyte therein is performed to generate the mixture of the oxygen and the hydrogen gas by electricity being applied from an electrical conversion device and having a plurality of electrode plates arranged with separation, a insulating materials attached to inner wall surfaces of the electrolytic cell and having at least one surface grooves formed thereon into which the electrode plates are inserted, a water supply device for supplementing the water into the electrolytic cell, the water supply device connected to the electrolytic cell, a gas reservoir for restoring the mixture generated in the electrolytic cell, the gas reservoir connected to the electrolytic cell, and a cooling unit for maintaining temperature inside the electrolytic cell constant connected to the electrolytic cell.

Abstract: A valve body is provided with a valve chamber with a predetermined size having at both ends a fluid inlet and a fluid outlet, a coil spring mounted within the valve chamber of the valve body and expanding and contracting depending upon a variation of fluid temperature with respect to a predetermined value, and a needle inserted into the coil spring for opening and closing fluid passages by moving leftward and rightward within the valve chamber in response to the expansion and contraction of the coil spring.
