Abstract

The invention discloses a variable passage volute device, which comprises a volute. An intake passage is reserved in the volute, a volute air inlet and a volute air outlet which are respectively communicated with the intake passage are arranged on the volute, an arc pneumatic partition is arranged in the volute intake passage, the volute intake passage is divided into an inner volute intake passage and an outer volute intake passage by the pneumatic partition, and an adjustable valve device is arranged at one end, close to the volute air inlet, of the pneumatic partition. The variable passage volute device is simple in structure, easy in control means implementation and high in reliability, the supercharging requirement of an engine in low speed, medium speed and high speed can be met effectively by using the variable passage volute device, the whole structure of a supercharger is changed slightly, and the supercharger is low in cost, easy in implementation, has high marketing value and can achieve a great application effect.

Description

technical field [0001] The invention relates to a volute device, in particular to a volute device with a variable flow channel that satisfies the requirements of low-speed, medium-speed and high-speed working conditions of the engine by working separately or jointly with the variable flow channels. The field of internal combustion engine supercharging. technical background [0002] At present, with the increasingly stringent emission regulations, turbochargers are widely used in modern engines. In order to meet the performance and emission requirements of the engine under various operating conditions, the turbocharger must have adjustable boost pressure and exhaust pressure. , thus the variable cross-section supercharger has become the focus of research and development at home and abroad. [0003] The rotary vane variable cross-section turbocharger VNT is widely used because of its simple structure and the ability to effectively broaden the matching range between the turb...
