Description

Piston cooling spray hook

Technical Field

The utility model relates to an engine cooling technical field, more specifically say, it relates to a hook is spouted in piston cooling.

Background

In the operation process of the engine, fuel is combusted in the cylinder body to push the piston to do work, the temperature of the piston is high, cooling oil can be sprayed to the piston through the piston cooling spray hook to cool, and the working stability of the piston is guaranteed. At present, a piston cooling spray hook is mechanical, oil is supplied through an oil pump, the oil pressure counteracts the elastic force of a spring to open, and the spray hook always sprays oil in the running process of an engine. When the engine rotates at a low speed (such as idling), the rotating speed of the oil pump is low, and the spray hooks of the multiple cylinders work simultaneously, so that the pressure of an oil lubricating system is reduced easily, the lubricating effect of the engine is influenced, and the working stability of the engine is influenced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is not enough to the above-mentioned of prior art, the utility model aims at providing a hook is spouted in piston cooling can solve and spout the hook and cause the problem of the pressure reduction of machine oil lubricating system at the oil spout all the time.

The technical scheme of the utility model is that: the utility model provides a hook is spouted in piston cooling, includes spouts the hook body, the output that spouts the hook body is equipped with the solenoid valve, solenoid valve electric connection ECU controller, the input that spouts the hook body is equipped with the pressure accumulation chamber, the pressure accumulation chamber is through first oil pipe connection oil pump.

As a further improvement, the pressure accumulation cavity is connected with the first oil pipe through a first one-way valve.

Furthermore, a pressure sensor electrically connected with the ECU controller is arranged in the pressure accumulation cavity.

Further, the pressure storage cavity and the spray hook body are in circular arc transition.

Furthermore, a second oil pipe surrounds the periphery of the electromagnetic valve, one end of the second oil pipe is connected with the first oil pipe, and the other end of the second oil pipe is connected with the pressure accumulation cavity.

Furthermore, a second one-way valve is arranged on the second oil pipe.

Advantageous effects

Compared with the prior art, the utility model, the advantage that has does:

the utility model discloses in open at the moment control solenoid valve of setting for through the ECU controller to close after the continuous set time, can reduce the oil spout under the lubricated prerequisite of assurance, can reduce machine oil lubricating system's pressure drop, when the low rotational speed (like the idle) of engine, also can guarantee machine oil lubricating system's pressure.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: the device comprises a spray hook body 1, an electromagnetic valve 2, an ECU controller 3, a pressure storage cavity 4, a first oil pipe 5, a first check valve 6, a pressure sensor 7, an arc 8, a second oil pipe 9, a second check valve 10, a cylinder body 11 and a piston 12.

Detailed Description

The invention will be further described with reference to specific embodiments shown in the drawings.

Referring to fig. 1, a piston cooling spray hook includes a spray hook body 1, and a nozzle of the spray hook body 1 sprays engine oil to a piston 12 in a cylinder block 11 to lubricate and cool the piston 12. Spout the output of hook body 1 and be equipped with

solenoid valve

2, 2 electric connection ECU controllers 3 of solenoid valve, spout the input of hook body 1 and be equipped with pressure storage chamber 4, and pressure storage chamber 4 connects the oil pump through first oil pipe 5.

Preferably, the pressure accumulation cavity 4 is connected with a first oil pipe 5 through a first check valve 6, and when the engine is stopped, certain engine oil can be stored in the pressure accumulation cavity 4 through the first check valve 6 and the electromagnetic valve 2.

And a pressure sensor 7 electrically connected with the ECU controller 3 is arranged in the pressure storage cavity 4 and used for detecting the pressure in the pressure storage cavity 4 in real time.

The pressure storage cavity 4 and the spray hook body 1 are transited through an arc 8.

The periphery of the electromagnetic valve 2 is surrounded by a second oil pipe 9, one end of the second oil pipe 9 is connected with the first oil pipe 5, the other end of the second oil pipe 9 is connected with the pressure accumulation cavity 4, and heat generated by the electromagnetic valve 2 is carried away through lubricating oil flow. The electromagnetic valve 2 can be cooled, and the second oil pipe 9 is provided with a second one-way valve 10.

The utility model discloses in can open at the moment control solenoid valve of setting for through the ECU controller to close after the continuous set time, can reduce the oil spout under the lubricated prerequisite of assurance, can reduce machine oil lubricating system's pressure drop, when the low rotational speed (like the idle) of engine, also can guarantee machine oil lubricating system's pressure.

The above is only a preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility of the invention and the utility of the patent.
