It is installed between the engine and the transmission, uses hydraulic oil as the working medium, and plays the role of transmitting torque, torque conversion, speed change and clutch. The pump wheel is connected to the driving shaft, and can convert the mechanical energy input by the driving shaft into the kinetic energy and pressure head of the liquid by the action of centrifugal force for the turbine to do work; the turbine is connected to the driven shaft, and the kinetic energy of the liquid and the energy contained in the pressure head can be output by the driven shaft. There are two common types of hydraulic torque converters: split type and integrated type. The split type means that the torque converter is separated from the transmission, and the transmission is connected in the middle by a transmission shaft. This type of transmission is generally a fixed shaft type. The integrated type means that the torque converter is connected to the transmission, and this type of transmission is generally a planetary type.

[0003] In order to ensure that the split torque converter has a certain back pressure during operation and give full play to the performance of the torque converter, an outlet valve needs to be installed on the outlet oil line of the torque converter housing.

[0027] The cone spring 2 uses spring force to push the cone valve core 1 against the connection between the valve hole 6 and the oil outlet channel 8; the compression amount of the cone spring 2 is changed by the screw plug 3 to adjust the opening pressure of the cone valve core 1.

[0028] The screw plug 3 has a mounting hole 4 and a hexagonal hole 5 connected thereto inside. The mounting hole 4 and the hexagonal hole 5 penetrate the screw plug 3 and are arranged in a colinear manner.

[0029] The mounting hole 4 is used for placing the large diameter end of the conical spring 2 .

[0030] The hexagonal hole 5 can be used for screwing the screw plug 3 and also for the circulation of hydraulic oil.

[0031] An internal thread 7 is provided in the large diameter end of the valve hole 6, and the screw plug 3 is connected to the internal thread 7, and the position can be adjusted through the threaded connection.
