Problems solved by technology

[0005] However, in actual use, when the fluid pressure of the cooling oil is too high due to the blockage of the external cooling device, etc., it will also cause the problem of insufficient oil supply of the gearbox cooling oil.

Embodiment Construction

[0037] The present invention provides a thermostat. By setting a cut-off sleeve that can move up and down in the cavity of the valve body, the cut-off sleeve is pressed against the inner wall of the cavity by an elastic element, and the outer diameter of the cut-off sleeve is smaller than the inner diameter of a part of the cavity. When adjusting When the fluid pressure in the thermostat is too high, the fluid can push the shut-off sleeve to compress the elastic element, so that a pressure relief channel is formed between the shut-off sleeve and the inner wall of the cavity, which can prevent damage caused by excessive fluid pressure in the thermostat.

[0038] The initial deformation force mentioned in the present invention refers to the pressure received when the elastic element in the compressed state of the product is deformed under the action of an external force when the product is not in use.

[0039] The present invention will be described in detail below in conjunction...

Abstract

The invention discloses a temperature adjuster. A flow stopping sleeve which can move up and down is arranged in a cavity of a valve body. The flow stopping sleeve is tightly pressed by elastic elements and abuts against a step face of the cavity in a connected manner. The outer diameter of the flow stopping sleeve is smaller than the inner diameter of a part of the cavity. When the fluid pressure in the temperature adjuster is excessively large, fluid can push the flow stopping sleeve to compress the elastic elements, so that a decompression channel is formed between the flow stopping sleeve and the inner wall of the cavity, and a first flow channel and a third flow channel communicate at the same time. In this way, the damage caused by excessively large fluid pressure in the temperature adjuster can be prevented.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to a gearbox thermostat. Background technique [0002] During the driving process of the car, lubricating oil needs to be replenished in time to ensure the normal operation of the car. If the lubrication performance of the lubricating oil is not good enough, it will greatly reduce the service life of the car and even cause a car accident. The lubricating performance of the lubricating oil has a great relationship with its own temperature. When the temperature of the lubricating oil is too high or too low, the lubricating oil will lose its lubricating performance. [0003] The temperature of the lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, the vehicle is driving under the condition of excessive slippage of the hydraulic torque converter, which may cause gear shifting.
