specific Embodiment approach

[0046] The orientation nouns such as top, bottom, left, and right described in the present invention are all described according to the relationship between up, down, left, and right in the accompanying drawings;

[0047] The initial deformation force of the first elastic member 203 in the present invention means that when the first elastic member 203 is compressed and deformed by the pressure of the push rod 205 so that the retaining ring 121 no longer bears the pressure exerted by the first elastic member 203 The pressure that an elastic member 203 bears.

[0048] The above definitions are applicable in all statements herein, and will not be repeated hereafter.

[0049] Such as Figure 1 to Figure 4 The thermostat shown includes a valve body 102 with a cavity 108 inside and a thermodynamic element installed in the cavity 108. It is characterized in that the cavity 108 communicates with the outside through at least three valve ports: the first valve port 104. The second val...

Embodiment 1

[0066] Example 1 as Figure 9 to Figure 13 As shown, the end cover 101 is an opening part with a cavity 171 inside, and the opening end of the end cover 101 is fixedly connected to the shut-off ring 111 through at least one connecting piece 141. In this embodiment, the end cover 101 and the shut-off ring 111 are integrally structured .

[0067] Specifically, a fluid flow hole 151 is provided between the end cap 101 and the shut-off ring 111 , and the second valve port 105 , the flow hole 151 , the inner hole of the shut-off ring 111 and the first valve port 104 communicate to form a first flow channel.

[0068] A first groove 131 for installing the first sealing ring 103 is formed on a peripheral side of the end cap 101 . A slot 181 for installing the washer 119 is provided inside the open end of the end cover 101 . Example 2 as Figure 14 to Figure 18 As shown, the technical solution of this embodiment is basically the same as that of Embodiment 1. The difference lies in ...

Abstract

The invention relates to a temperature regulator. The temperature regulator comprises a valve body and a thermodynamic element, wherein a cavity is formed in the valve body, and the thermodynamic element is mounted in the cavity; the cavity is communicated with the outside through at least three valve ports, namely a first valve port, a second valve port and a third valve port, the two ends of the thermodynamic element are respectively mounted in the valve body through elastic components, a flow cutoff ring which is of an annular component is mounted in the cavity in a sealed and fixed manner, and a thermodynamic element body is located between the third valve port and the flow cutoff ring. When the temperature of fluid is relatively low, a heat-sensitive material in the thermodynamic element contracts, and the thermodynamic element body moves towards the flow cutoff ring and closes an internal hole of the flow cutoff ring; when the temperature of the fluid is relatively high, the heat-sensitive material in the thermodynamic element expands, and the thermodynamic element body moves towards the third valve port until the third valve port is closed by the thermodynamic element body. The temperature regulator provided by the invention has the advantage that the internal leakage of temperature regulators in the prior art is lowered greatly.

Description

technical field [0001] The invention relates to the field of heat exchange, more specifically, to a 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 lubricating oil is closely related to its own temperature. When the temperature of 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. Oil temperature is to...
