Abstract

A fluid supercharging device (3, 5), comprising: a rotating shaft (7); a vane disc (308) coaxially fixed to the rotating shaft (7); a plurality of fan blades (301) fixed around a perimeter of the vane disc (308); the back side of the fan blades 301 being provided with at least one fluid guiding inlet (305), an end of the back side distal from the vane disc (308) is provided with a fluid guiding outlet (306, 307), a fluid channel (304) communicating the fluid guiding inlet (305) with the fluid guiding outlet (306, 307) is provided along a lengthwise direction inside the fan blades; the fan blades (301) rotate to generate a centrifugal force such that a fluid flows into the fluid channel via the fluid guiding inlet on the back side, and flows out of the fluid guiding outlet along the lengthwise direction of the fan blades.

Claims7

Dependent claims

An engine, comprising:

a housing (1), the housing being a hollow housing, a front portion of the housing (1) being a gas intake passage (2), a rear portion of the housing (1) being a jetting port (6), an inner portion of the housing (1) being combustion chamber (4), a compressor (3) and a turbine (5) being provided coaxially with a rotating shaft (7) and received in the housing (1);
Wherein a rear portion of the compressor (3) is provided, coaxially with the rotating shaft (7), with a hollow rotating cylinder (702) with a higher rotation velocity, a pressure differential propelling force from the front to the rear being generated between the compressor (3) and the hollow rotating cylinder (702) due to different flow velocities;
wherein the hollow rotating cylinder (702) is received in the combustion chamber (4), and the hollow rotating cylinder (702) during rotation throws a fluid therein to the outside to define a hollow state;
and a fluid in the combustion chamber (4) is sufficiently combusted in the course of traveling on a longer path around the hollow rotating cylinder (702).
