Nozzle, engine and vehicle

Abstract

The invention relates to the technical field of traffic work, and discloses a nozzle, an engine and a vehicle, the nozzle comprises a hollow valve body, a temperature control valve body, a ball valve, a first elastic piece and a second elastic piece, and the hollow valve body is internally provided with a valve channel; the inner wall of the valve channel is provided with an abutting face, the ball valve is located in the valve channel, and the first elastic piece is used for providing restoring force for the ball valve so that the ball valve can abut against the abutting face in the extending direction of the valve channel. The temperature sensing body is used for driving the end, away from the ball valve, of the first elastic piece to move in the restoring force reducing direction when the temperature rises. The second elastic piece is used for driving the end, away from the ball valve, of the first elastic piece to move in the restoring force increasing direction. When the engine oil temperature is high due to the vehicle conditions such as vehicle climbing, the cooling required flow of the piston and the like is relatively increased, the engine oil temperature is transmitted to the temperature sensing body, the temperature sensing body deforms to drive the end, away from the ball valve, of the first elastic piece to move in the direction of reducing the restoring force, and therefore the initial opening pressure of the ball valve is reduced, and the flow of the nozzle is increased.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a nozzle, an engine and a vehicle. Background technique [0002] In order to reduce the heat load of the piston and strengthen the lubrication of the piston pin and connecting rod bearing, the engine is equipped with lubricating oil cooling nozzles. The commonly used lubricating oil cooling nozzles are generally controlled by the pressure control valve. However, when the working conditions change When the oil temperature changes, pressure control alone cannot meet the cooling oil flow requirements of the piston pin shaft and connecting rod bearings, resulting in increased heat load on the piston or overcooling of the piston.

[0002] In order to reduce the heat load of the piston and strengthen the lubrication of the piston pin and connecting rod bearing, the engine is equipped with lubricating oil cooling nozzles. The commonly used lubricating oil cooling nozzles are generally controlled by the pressure control valve. However, when the working conditions change When the oil temperature changes, pressure control alone cannot meet the cooling oil flow requirements of the piston pin shaft and connecting rod bearings, resulting in increased heat load on the piston or overcooling of the piston

[0003] The current solution to this problem is to use electronically controlled piston cooling nozzles. Although the control accuracy is high, the cost is high, the calibration is relatively complicated, and the flow rate cannot be adaptively adjusted according to the oil temperature.
