Abstract
A one-way pumping device and its application devices, so as to enhance the resistance difference effect between the forward direction and the reverse direction of the one-way pumping device and realize a structure applicable to more application devices. To achieve the above purpose, this application provides the following technical solutions: a one-way pumping device, an artificial heart, and an internal combustion engine exhaust gas supercharging device.
Claims14
A one-way pumping device, wherein the one-way pumping device comprises two one-way pipes and a deformable pipe connected between the two one-way pipes;
- the two one-way pipes are arranged in one direction;
- the deformable pipe has radial or/and axial elasticity;
- the one-way pipe comprises at least one one-way pipe unit, and the one-way pipe unit comprises a main pipe wall, a shunt pipe and a bracket;
- the main pipe wall is in the shape of a hollow cone with a central through hole, being thin at one end and thick at the other end;
- the shunt pipe is in the shape of a horn with a central through hole, being thin at one end and thick at the other end;
- the shunt pipe is suspended and fixed inside the main pipe wall through the bracket, and the shunt pipe is arranged in the same direction as the corresponding main pipe wall, and the shunt pipe is arranged coaxially with the main pipe wall;
- the central through holes of the shunt pipe and the main pipe wall form a main channel;
- a shunt channel with a U-shaped cross-section is formed between the shunt pipe and the main pipe wall.
A device for exhaust gas supercharging of an internal combustion engine, the internal combustion engine body is provided with an exhaust pipe, wherein a one-way pumping device is arranged in the exhaust pipe;
- the one-way pumping device comprises two one-way valves and a deformable part connected between the two one-way valves;
- the deformable part is a pipe with elasticity;
- the two one-way valves are arranged in one direction;
- the exhaust gas of the internal combustion engine with changing pressure passes through the outside of the deformable part and acts on the deformable part to change its internal volume;
- due to the action of the one-way valves, the fluid inside the one-way pumping device flows unidirectionally.
