With reference to shown in Fig. 1, the turbosupercharger 100 according to the utility model embodiment comprises housing 1.Housing 1 is formed with suction port 6 and air outlet 7, in housing 1, limits eduction valve cavity 4, hyperbaric chamber 2 and the first communicating passage 3.Eduction valve cavity 4 is communicated with suction port 6, and hyperbaric chamber 2 is communicated with air outlet 7.
First communicating passage 3 is connected between eduction valve cavity 4 and hyperbaric chamber 2, particularly, one end of first communicating passage 3 is connected with eduction valve cavity 4, and the other end of the first communicating passage 3 is connected with hyperbaric chamber 2, and eduction valve cavity 4 is connected by the first communicating passage 3 with hyperbaric chamber 2.Pressurized gas in hyperbaric chamber 2 enter into relief valve cavity 4 by the first communicating passage 3, are then back to suction port 6 place of low voltage terminal further, carry out supercharging in the charging turbine flowing into turbosupercharger 100 further with the gas at suction port 6 place.
The cross-section area of the first communicating passage 3 is configured to reduce gradually along from one end be connected with hyperbaric chamber 2 of the first communicating passage 3 towards the direction of one end be connected with eduction valve cavity 4 of the first communicating passage 3.That is, the first communicating passage 3 is along from hyperbaric chamber 2 on the backflow direction of the direction of eduction valve cavity 4 and gas, and the cross-section area of the first communicating passage 3 reduces gradually.
Thus, on the backflow direction of gas, first communicating passage 3 is formed as the contracted channel of reducing type, and after the gas backstreaming in hyperbaric chamber 2 is by the first communicating passage 3 of this reducing type, the flowing velocity of gas can increase, gas pressure can reduce, when the gas flow that pressure reduces is to eduction valve cavity 4, gas reduces by the obstruction of the wall of eduction valve cavity 4, and the vortex phenomenon of generation reduces, gas flow is more smooth and easy, and the disappointing noise produced due to pressure rapid fluctuation significantly reduces.
In the related, the first communicating passage is formed as cylinder type pipeline, and in the boundary layer of wall, gas particle is subject to the obstruction of the frictional force that viscosity causes, and gas flow rate reduces.And after entering the eduction valve cavity 4 that sectional area becomes large, gas pressure raises, airspeed further reduces, so that in the local of eduction valve cavity 4, gas particle easily causes the phenomenon that halts, and simultaneously with the phenomenon that gas is separated with wall, and then forms eddy current, produce unnecessary aerodynamic noise, disappointing noise is larger.
And according to the worm wheel pressure booster of the utility model embodiment, the first communicating passage 3 being communicated with hyperbaric chamber 2 and eduction valve cavity 4 is formed as the pipeline of reducing type, the pipeline of this reducing type can reduce the pressure and temperature of the air-flow entering eduction valve cavity 4 in advance, avoid gas pressure fluctuation sharply in the process of suction port 6 being directly back to low voltage terminal from turbosupercharger 100 high voltage terminal that cylinder type pipeline Connecting format produces, make gas pressure more steady, disappointing noise significantly reduces.
