Embodiment Construction
[0019] as attached figure 1 Shown: an oil-water thermostat, which includes a thermostat bushing assembly 1 and a thermostat body 2. Thermostat bushing assembly 1 consists of threaded joint 1-1, thermostat bushing joint 1-2, thermostat bushing 1-3 and temperature sensing body 1 installed in thermostat bushing 1-3 -4 and thermostat ejector rod 1-7. The threaded joint 1-1 and the thermostat bushing joint 1-2 are threadedly connected, and the thermostat bushing joint 1-2 and the thermostat bushing 1-3 are fixedly connected together by welding. A return spring 1-8, a waterproof O-ring 1-6 and an oil-proof O-ring 1-5 are arranged on the thermostat push rod 1-7. An oil inlet nozzle 3 is arranged on the oil inlet hole of the thermostat body 2, and an oil outlet nozzle 4 is arranged on the oil outlet hole of the thermostat body 2, and the oil inlet hole of the thermostat body 2 is a tapered hole , The taper is 10°~45°. A bypass hole 2-1 is also provided between the tapered oil inle...

The invention relates to an oil-water temperature saver and a method for controlling the opening of a valve inside a temperature saver body by the temperature of an engine cooling water way. The oil-water temperature saver comprises a temperature saver sleeve assembly and a temperature saver body, wherein screwed connections arranged on the temperature saver body and the temperature saver sleeve assembly are connected together through screw threads, and adjusting washers are arranged between the temperature saver body and the screwed connections. The oil-water temperature saver is arranged on an engine water way in a connecting way through screw threads, and a temperature sensing body of the oil-water temperature saver is arranged in the engine water way, and the position of the temperature sensing body inside the engine water way is adjusted and fixed by a nut and a washer. In the invention the opening of the valve inside the temperature saver body is controlled by utilizing the temperature of the engine cooling waterway to automatically adjust the oil flow capacity of an oil valve so as to control the rotating speed of a fan with a hydrodynamic coupler, thereby the purpose of automatically controlling the engine temperature of vehicles is achieved. The starting control temperature of the oil-water temperature saver is between 70 DEG C and 90 DEG C.
Description
technical field [0001] The invention relates to the technical field of vehicle cooling systems, in particular to a device for automatically adjusting the temperature of a vehicle engine by controlling the opening of a valve in a thermostat according to the temperature of an engine waterway, thereby controlling the speed of a fan with a hydraulic coupling and methods. Background technique [0002] Generally, vehicles are equipped with heat sources such as engines, and the engine temperature must be automatically controlled within a certain range. Therefore, a fan with a certain displacement must be designed for cooling, and a thermostat with high sensitivity that matches the fan and automatically controls the fan speed must be designed. Deutz's BF / L413 series exhaust gas thermostat for air-cooled diesel engines can only collect the temperature of the exhaust pipe, which is affected by the large temperature range of the exhaust pipe and has poor sensitivity. The water channel...
