Embodiment Construction

[0010] figure 1 Among them, the ratio of the comb-shaped tongue (1) tooth to the cross-sectional area of ​​the rotating shaft (4) and the flow cross-sectional area of ​​the vortex tube at the split point (10) is K, and K=181 / 432; the comb-shaped tongue (1) tooth The ratio of the total mass (grams) to the sum of the cross-sectional area of ​​the gear shaft (mm2) is N, and N=(11 / 1086); the flow section (10) of the split point vortex tube is a square, and its side length is a, and the comb-shaped tongue (1) The tooth is a hollow cylindrical tooth, and the tooth length is set to b, b / a=8 / 9.

[0011] figure 2 In the vehicle-mounted installation, the central axis of the rotating shaft (4) is perpendicular to the wheel axis, the exhaust direction on the lower side of the scroll tube (6) is at an angle of 15 degrees to the plane of the four-wheel axis of the car, and the upper side of the scroll tube (5) is connected to the lower side of the scroll tube. The side (6) is symmetrical...

Abstract

The invention belongs to the technical fields of a mechanical engineering department, a general engineering division, a fluid pressure actuator large class, a servo motor subclass, a servo motor large group with a servo function and an oscillating servo motor small group according to an international patent classification (IPC). The pressurizer is simple in structure and achieves full-time maximum efficiency pressurization. The pressurizer solves the problems that pressurization of a large turbine in the prior art is delayed, high-speed back pressure of a small turbine exists, a variable nozzle ring turbine is complex in structure, and material requirements are high. Meanwhile, the pressurizer has a social effect of energy conservation and emission reduction. An appended drawing of an abstract and an appended drawing of a specification 2 show: 1 a comb-shaped tongue piece, 2 a turbine, 3 a high-speed vortex, 4 a rotary shaft, 5 an upper side of a vortex tube, 6 a lower side of a vortex tube, 7 a low-speed vortex, 8 exhaust gas drainage, 9 a minimum cross section of a volute inlet, 10 a flow section of the vortex tube at distribution point, and 11 a volute. A comb-shaped tongue piece shunting variable cross-section turbine pressurizer is implemented as the appended drawings that the comb-shaped tongue piece (1) divides the exhaust gas drainage (8) into the high-speed vortex (3) and the low-speed vortex (7), a pressure difference of the exhaust gas drainage (8) and the low-speed vortex (7) can swing the comb-shaped tongue piece (1) to change a cross section of the high-speed vortex (3) and implement the work.

Description

(1) Technical field: [0001] The invention relates to a variable cross-section turbocharger, classified according to the International Patent Classification (IPC), belonging to mechanical engineering; lighting; heating; weapons; blasting department; general engineering division, fluid pressure actuator; Class, general fluid working systems; fluid pressure actuators, such as servo motors; subclass of fluid pressure components not included in other classes, servo motors with follow-up action, that is, the position of the driven part is consistent with the control part; It has the technical field of reciprocating or oscillating servo motor group. (two) background technology: [0002] At present, there are variable throat turbochargers, which have low efficiency; tongue-shaped baffle variable cross-section turbochargers, which have large flow loss, limited adjustment range, and low overall efficiency of the turbocharger; variable nozzle ring vortex supercharging The regulator (V...
