A variable geometry turbine having a wastegate includes a turbine housing, a power turbine, and a regulating valve. The turbine housing is provided with an inner intake gas flow channel and an outer intake gas flow channel. The turbine housing is further provided with a wastegate pipeline configured to bypass the power turbine, and a wastegate valve configured to control communication of the wastegate pipeline. One of the regulating valve and the wastegate valve has a regulating face having a varying axial height in a rotation direction of the regulating valve, and the other of the regulating valve and the wastegate valve has a linking portion which makes contact and cooperates with the regulating face. Thus, the efficiency of the turbine is improved significantly and backflow of the gas flow is reduced.

Variable geometry wastegate turbine

A centrifugal compressor, including: a housing, the housing including: an inlet, a flow channel, an impeller outlet, and an air diffusing channel; a centrifugal impeller disposed inside the housing; a rotating wall, the rotating wall including a front cascade; and a rotating disc, the rotating disc including a rear cascade. The impeller outlet is disposed adjacent to a rear part of the centrifugal impeller and is connected to the flow channel via the air diffusing channel. The rotating wall is disposed between the centrifugal impeller and the housing. The front cascade is disposed inside the front part of the rotating wall and is connected to a dynamic driving device. The rotating disc is disposed inside the housing adjacent to the air diffusing channel and is in a rigid connection with the rotating wall.

Centrifugal compressor

A turbine device, including: a turbine housing including an inlet, a flow channel, an outlet, a middle partition, an arced partition; a turbine impeller; a gas outlet; and an exhaust manifold. The turbine impeller and the gas outlet are arranged inside the turbine housing. The exhaust manifold is connected to the inlet. The flow channel is arranged inside the turbine housing. The outlet is arranged on the flow channel close to the turbine impeller. The middle partition is disposed inside the flow channel and divides the flow channel into a left flow channel and a right flow channel. The arced partition is arranged in both the left and right flow channels. One end of the arced partition is in a rigid connection with the middle partition, and the other end of the arced partition is close to the outlet of the turbine housing.

Turbine device

A compressor unit including a compressor housing, a compressor impeller, a gas diffuser channel, a cylinder-shaped rotating diffuser wall, and a supporting device. The compressor housing includes an air inlet and an air collection channel. The compressor impeller is installed in the compressor housing. The gas diffuser channel is disposed between the compressor impeller and the air collection channel and connected to the air collection channel. The cylinder-shaped rotating diffuser wall is disposed between an inner wall of the compressor housing and the compressor impeller and rotates in the same direction as the compressor impeller. The supporting device is disposed in the compressor housing to support the cylinder-shaped rotating diffuser wall. The compressor unit has high response speed, large air inlet flow, and high efficiency.

Compressor unit

A turbocharger turbine having a double-layer flow passage and a variable cross-section, including a turbine housing, a volute diffuser channel, a power turbine, a volute gas feeding passage, and a partition wall. The volute gas feeding passage is arranged in the turbine housing. The partition wall is arranged in the volute gas feeding passage and divides the volute gas feeding passage into an external volute gas feeding passage and an internal volute gas feeding passage. The external volute gas feeding passage is located outside the internal volute gas feeding passage. The combination of the external and internal volute gas feeding passages forms different flow areas, sufficiently utilizing the waste gas energy of engines in a segmented mode. The variable cross-section turbine has a simple structure, is easy to upgrade at low cost, and can be easily mass-manufactured.
