Abstract: A pressure releasing valve capable of reserving air pressure is formed with a pressure reserving chamber to retain a proper amount of air pressure in the pressure releasing valve when the engine is changing from an accelerating and increasing pressure condition to a condition of running idly and releasing pressure, so that when the engine accelerates and increases pressure again, air of the condenser can be continually supplied for the engine to let it run comparatively smoothly in accelerating, not only economizing energy but ensuring safety as well.

Abstract: A one-stage transmissible turbocharger includes a turbine wheel contained in a front current-guider and a rear current-guider, increasing air pressure to elevate horsepower and speeding up burning of gas coming out of a carburetor to save fuel consumption. The turbine wheel has a plurality of leaves respectively helically formed to have 32 angles to make a catch inlet section to elevate air volume to be caught in, and a final axial pressure section for producing centrifugal current so as to give the turbine wheel functions of both axial current and centrifugal current. In addition, the turbocharger has buffer springs for protecting a belt wheel and its bolts from damaged or broken.
