A syringe type device for checking oil < RTI ID = 0.0 >

The present invention relates to an oil check valve, more particularly, to an oil check valve which employs a syringe type and a structure that facilitates mutual comparison of oil to be checked and unused oil, thereby facilitating replacement of engine oil, Type syringe-type oil check valve.

In automobiles, many mechanical parts such as engines and transmissions are organically coupled. Various oils such as engine oil, brake oil, mission oil and power steering oil are injected for smooth operation of these mechanical parts.

The oil forms an oil film on the friction surface of each part to reduce friction and abrasion, while cooling the friction surface and suppressing corrosion.

For this purpose, the oil must maintain an appropriate viscosity. When the vehicle is driven for a certain period of time, the viscosity of the lubricating oil is lowered and the lubrication function is largely degraded or lost.

Particularly, in the case of engine oil, partial oxidation and abrasion due to surface abrasion are contained in a large amount, and the foreign matter is deteriorated due to high temperature and the viscosity of the engine oil is lowered, .

Therefore, after using engine oil for a certain period of time, it should be discharged and replaced with new oil.

The driver will often check the condition of the oil according to the planned inspection period and, if necessary, determine the oil change.

In case of engine oil, for example, first pull out the engine oil gauge, wipe the indicator line of the gauge with a clean cloth, and then insert it again. After that, pull out the gauge again and check whether the amount of engine oil indicated on the indicator of the gauge is proper. At this time, check the color and viscosity of the engine oil and measure the replacement time.

New engine oil often has a light red or grayish brown color, but after the engine oil has been used in the vehicle engine, it becomes dark brown or black due to the mixing of foreign matter. In addition, the viscosity of the engine oil changes depending on the degree of deterioration, i.e., the degree of contamination, depending on the amount of impurities or the degree of deterioration.

Therefore, the inspector can check the color and viscosity of the engine oil to determine whether or not to exchange.

However, according to the conventional method of checking the engine oil, it is difficult to gauge at a glance how much the color of the engine oil is discolored compared to the oil color of the original state.

That is, since the new oil which is often compared with the oil collected at the time of the oil check is not provided separately for this comparison, the general driver can rely on the judgment of the expert or simply judge the operating distance of the vehicle, .

In this case, if the oil is changed too early, the oil can not be used properly and the oil is replaced. Therefore, unnecessary cost is wasted, and if the oil is exchanged too late, the life of the engine is reduced.

This is not only a problem with engine oil, but also with brake oil, mission oil and power steering oil.

A syringe type oil check valve capable of comparing the degree of discoloration of the oil and the degree of contamination with new oil at a glance to determine a correct oil change time, The present invention has been made in view of the above problems.

In order to achieve the above-mentioned object, the syringe type oil check valve according to the present invention comprises: a cylinder part having a low oiling space formed therein, A suction portion provided in the front end of the cylinder portion and having an oil suction path formed therein; And an oil reservoir capable of moving inward and backward in the cylinder and guiding oil in and out through the suction unit in accordance with forward and backward movements, And a piston portion having a piston shaft coupled to a rear end portion of the oil reservoir portion and a handle portion formed at a rear end portion of the piston shaft.

According to the present invention, the difference in color between the new unused oil stored in the oil reservoir and the oil to be inspected into the cylinder can be seen at a glance, so that the degree of discoloration of the oil to be checked can be easily determined, In addition, there is an advantage that the degree of pollution of the oil to be checked can be accurately compared with unused oil.

With this advantage, the driver can determine the exact oil change timing, and as a result, the maintenance cost of the automobile due to the efficient utilization of the oil can be reduced.

According to a preferred embodiment of the present invention, there is provided a syringe type oil check valve comprising: a cylinder portion having an oil storage space formed therein; A suction portion provided in the front end of the cylinder portion and having an oil suction path formed therein; And an oil reservoir capable of moving inward and backward in the cylinder and guiding oil in and out through the suction unit in accordance with forward and backward movements, And a piston portion having a piston shaft coupled to a rear end of the oil reservoir portion and a handle portion formed at a rear end portion of the piston shaft.

In this case, the cylinder portion includes a cylinder body through which the inside can be seen, a front cover coupled to the front end portion of the cylinder body and coupled with the intake portion, and a through hole coupled with the rear end portion of the cylinder body, And a rear cover formed thereon.

For example, the cylinder body 110 may be made of a material such as glass or transparent plastic.

The front cover 120 and the rear cover 130 may be detachably coupled to both opened ends of the cylinder body 110. In an example of the coupling type, a thread is formed on the outer circumferential surfaces of both end portions of the cylinder body 110 Screw grooves are formed on the inner circumferential surfaces of the front and rear covers 120 and 130 so as to be screwed together.

A through hole 131 is formed in the rear cover 130 so that a piston shaft 320 to be described later penetrates through the front cover 120 and a reciprocating motion can be freely made. do.

In this case, it is preferable that the front cover 120 is coupled with the cylinder body 110 so that the suctioned oil is kept airtight so as to prevent the oil from leaking through the joint between the front cover 120 and the cylinder body 110 .

The cylinder part 100 is not limited to the example of the cylinder part 100 described above and the cylinder part 100 is formed integrally with the cylinder body 110 and the front cover 120, The cover 120 may be integrally formed with a suction unit 200 to be described later and the rear end of the cylinder body 110 may be formed to be opened for insertion of the piston unit 300 to be described later. That is, it can be manufactured in a shape of a syringe body which is commonly used.

The suction unit 200 is coupled to the front cover 120. 1 to 4 show an example in which a separate suction unit 200 is coupled to the front cover 120. However, the suction unit 200 is not limited to this example, and as mentioned above, It may be formed integrally with the base 120.

A suction path 201 penetrating from the front end to the rear end is formed in the suction part 200. The suction path 201 is communicated with the inside of the cylinder body 110, The oil 20 can be sucked.

1 to 4, the suction unit 200 has a pointed long conical shape toward the tip. In this case, a rubber tube (not shown) or the like may be further coupled to the suction unit 200 so that the oil can be easily sucked in the oil tank when the oil is sucked. In order to easily couple the rubber tube to the suction unit 200 Shape. However, even when a rubber tube or the like is required, the suction tube 200 and the suction tube 200 can be coupled by various coupling methods, so that the suction tube 200 need not necessarily have such a shape.

In the cylinder part 100, the piston part 300 is coupled to be reciprocatable. The piston part 300 is inserted through the rear end of the cylinder part 100. The piston part 300 reciprocates forward and backward in the cylinder part 100 to move the check oil 20 through the suction part 200, (Not shown).

A more specific example of the piston 300 may include an oil reservoir 310, a piston shaft 320, and a handle 330.

The oil storage part 310 serves as a piston and stores new unused oil 10 which is not used in a vehicle while being kept in a hermetic state. Then, this inside can be viewed.

As a specific example of the oil storage part 310, the oil storage part 310 may include a storage body 311 and front and rear covers 312 and 313.

The storage body 311 is formed in a cylindrical shape having an outer diameter smaller than the inner diameter of the cylinder body 110, and a space for storing the unused oil 10 is formed therein. And it can be made of glass or transparent plastic material so that the inside can be seen through.

At both open ends of the storage unit body 311, the front and rear covers 312 and 313 are coupled so that the interior of the storage unit body 311 can be hermetically sealed. The coupling method may be such that the front and rear covers 312 and 313 are fixed at both ends of the storage unit body 311 while the unused oil 10 is stored in the storage unit body 311. [ In another coupling method, the front cover 312 or the rear cover 313 is detached from the storage body 311 so that the oil stored inside the storage body 311 can be replaced with the new oil when the oil check is performed for different kinds of oil. A screwed manner may be used.

At this time, the oil reservoir 310 is supported by the support rods 314 (see FIG. 3) in which both end portions of the oil reservoir 310 are coupled to the respective inner surfaces of the front and rear covers 312 and 313 to maintain the rigidity of the oil reservoir 310 with respect to the reciprocating motion of the piston 300 ) May be further included. The support rods 314 may be screwed at both ends through threaded grooves formed in the respective inner surfaces of the front and rear covers 312 and 313, but the present invention is not limited thereto. That is, since the oil reservoir 310 is not necessarily detachable, the support rod 314 may be coupled to the inner surfaces of the front and rear covers 312 and 313 at both ends thereof.

The oil reservoir 310 is not limited to the above configuration. Although not shown, a transparent capsule containing new unused oil is made to be detachably fitted in a groove formed in a cylindrical storage body, and a variety of configurations in which the unused oil stored in the oil storage part 310 can be viewed from the outside .

The piston shaft 320 is coupled to the rear end of the oil reservoir 310, specifically, the rear cover 313. The piston shaft 320 has an outer diameter smaller than that of the through hole 131 of the rear cover 130 included in the cylinder portion 100 and moves forward and backward through the through hole 131 .

A handle 330 is formed at the rear end of the piston shaft 320. The handle portion 330 is engaged in a screwed manner at the rear end of the piston shaft 320. [ Alternatively, the handle 330 may be integrally formed at the rear end of the piston shaft 320. In this case, When the user grasps and pulls the handle portion 330, the user moves backward the oil storage portion 310 connected to the piston shaft 320 and sucks the oil to be checked 20 through the suction portion 200 do.

Meanwhile, when the user pushes or pivots the piston unit 300, the cylinder unit 100 is moved from one side of the outer circumferential surface of the oil reservoir 310 so that the external force acting on the piston unit 300 can be fully transmitted to the suction force or the output of the oil. It is preferable that the air is prevented from flowing to the rear side of the air bag.

In this embodiment, the packing 400 is coupled to the outer surfaces of the front and rear covers 312 and 313 included in the oil reservoir 310. The packing 400 may be made of a material such as rubber or silicone, and an O-ring having an O-shape in cross section may be used.
