Description

Technical Field

[0001] The utility model relates to the technical field of engine cooling, in particular to a double-headed piston cooling nozzle. Background Art

[0002] As engine performance continues to improve, the thermal load on the piston assembly gradually increases. To prevent engine piston assembly failure due to high temperature, more and more gasoline engines are beginning to use piston cooling nozzles. These nozzles spray cooling oil into the piston to achieve the purpose of cooling the piston.

[0003] At present, common piston cooling nozzles are mainly single-nozzle structures. Only one beam of engine oil is sprayed into the cooling oil channel inside the piston, and flows out from the other end of the oil channel after passing through the cooling oil channel inside the piston. It mainly cools the piston, but the cooling and lubrication of the piston bottom and piston pin are insufficient. Piston carbon deposits and cylinder scuffing are prone to occur during engine use. The piston bottom is not cooled enough and turns black. The engine oil deteriorates quickly due to high temperature. The piston pin is not lubricated enough and causes it to get stuck. The existing patent CN217354551U provides a dual-cooling nozzle for engine pistons. However, the nozzle body and spring seat in the patent are reinforced by laser welding. After adopting this method, the pressure of opening the one-way valve cannot be adjusted according to actual usage. Excessive pressure will cause the nozzle to be unable to spray cold oil or too low pressure will cause leakage. In view of this, a double-headed piston cooling nozzle is proposed.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The utility model provides a new technical solution: a double-headed piston cooling nozzle, comprising a nozzle mounting plate 1, a nozzle body 2 fixedly sleeved on the inner surface of the nozzle mounting plate 1, a secondary nozzle 3 fixedly mounted on the outer surface of the nozzle body 2, and a main nozzle 4 fixedly mounted on the outer surface of the nozzle body 2;

[0027] Among them, an adjustment mechanism is provided in the nozzle body 2, which includes a spring seat 5, a first spring 6, a steel ball 7, three sealing grooves 8, a slide groove 9, two second springs 10, two fixing plates 11, a ring 12, two round holes 13, two round balls 14, a rubber sealing ring 15 and six clamping holes 16.

[0028] Furthermore, the spring seat 5 is arranged on the inner surface of the nozzle body 2 , the rubber sealing ring 15 is fixedly sleeved on the outer surface of the spring seat 5 , and six clamping holes 16 are opened on the outer surface of the spring seat 5 .

[0029] Furthermore, a first spring 6 is fixedly mounted on the upper surface of the spring seat 5 , and a steel ball 7 is provided on the upper surface of the first spring 6 .

[0030] Furthermore, three sealing grooves 8 are formed on the inner surface of the nozzle body 2 , and a sliding groove 9 is formed on the outer surface of the nozzle body 2 .

[0031] Furthermore, two second springs 10 are fixedly mounted in the inner wall of the chute 9, and two fixing plates 11 are fixedly mounted on the lower ends of the two second springs 10, respectively. The lower surfaces of the two fixing plates 11 are inclined.

[0032] The circular ring 12 is fixedly mounted on the outer surfaces of the two fixed plates 11 , and the circular ring 12 is slidably connected to the sliding groove 9 .

[0033] Furthermore, two circular holes 13 are provided on the inner surface of the chute 9, and two round balls 14 are respectively provided on the inner surfaces of the two circular holes 13;

[0034] When the double-headed piston cooling nozzle is in use, an upward thrust is applied to the circular ring 12 to make it move upward, and at the same time, the circular ring 12 drives the two fixed plates 11 fixedly installed on the inner surface to move upward. At this time, the two fixed plates 11 apply pressure to the two second springs 10 fixedly installed on the upper surface, causing them to shrink. At this time, the two fixed plates 11 no longer block the two circular holes 13, that is, they no longer limit the two round balls 14 set in the two circular holes 13. At this time, by inserting the spring seat 5 into the inner surface of the nozzle body 2, an upward thrust is no longer applied to the circular ring 12, and the two second springs 10 are no longer under force. At this time, the two second springs 10 press on the two second springs fixedly installed at the lower end. The fixing plate 11 applies a downward thrust to make it hit the two balls 14, and applies a thrust to the opposite surfaces of the two balls 14, so that the two balls 14 move toward the opposite surfaces and are engaged in the engaging holes 16 opened on the outer surface of the spring seat 5 for fixation. By installing the balls 14 in different engaging holes 16, the depth of the spring seat 5 entering the nozzle body 2 can be adjusted. The deeper the depth, the greater the pressure to open the nozzle body, and vice versa. The opening pressure becomes smaller, which can be adjusted according to actual usage. After the spring seat 5 is installed, the rubber sealing ring 15 fixedly installed on the outer surface of the spring seat 5 is filled into the sealing groove 8 opened on the inner surface of the nozzle body 2 for sealing to prevent leakage.

[0035] The double-headed piston cooling nozzle can connect the spring seat 5 and the nozzle body 2 by means of a snap connection, and the installation depth of the spring seat 5 can be adjusted to change the pressure applied by the first spring 6 to the steel ball 7, that is, to adjust the pressure at which the one-way valve opens. The pressure can be changed for use according to actual conditions, which is more convenient. In addition, when the spring seat 5 and the nozzle body 2 are connected, the double-headed piston cooling nozzle seals the nozzle body 2 through the rubber sealing ring 15 fixedly mounted on the outer surface of the spring seat 5 and the sealing groove 8 opened on the inner surface of the nozzle body 2 to prevent leakage during use, making it more convenient to use.

[0036] Working principle: When the double-headed piston cooling nozzle is used, an upward thrust is applied to the circular ring 12 to make it move upward, and at the same time, the circular ring 12 drives the two fixed plates 11 fixedly installed on the inner surface to move upward. At this time, the two fixed plates 11 apply pressure to the two second springs 10 fixedly installed on the upper surface, causing them to shrink. At this time, the two fixed plates 11 no longer block the two circular holes 13, that is, they no longer limit the two round balls 14 set in the two circular holes 13. At this time, by inserting the spring seat 5 into the inner surface of the nozzle body 2, an upward thrust is no longer applied to the circular ring 12, and the two second springs 10 are no longer under force. At this time, the two second springs 10 are fixed on the lower end. The two fixing plates 11 apply a downward thrust to make them hit the two balls 14, and apply a thrust to the opposite surfaces of the two balls 14, so that the two balls 14 move toward the opposite surfaces and are engaged into the engaging holes 16 opened on the outer surface of the spring seat 5 for fixation. By installing the balls 14 in different engaging holes 16, the depth to which the spring seat 5 enters the nozzle body 2 can be adjusted. The deeper the depth, the greater the pressure to open the nozzle body, and conversely, the opening pressure becomes smaller. It can be adjusted according to actual usage, and after the spring seat 5 is installed, the rubber sealing ring 15 fixedly installed on the outer surface of the spring seat 5 is filled into the sealing groove 8 opened on the inner surface of the nozzle body 2 for sealing to prevent leakage.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
