도 3은 본 발명에 따른 엔진의 메인 갤러리 압력조절장치에 대한 구성을 설명하기 위한 블럭도.Figure 3 is a block diagram for explaining the configuration of the main gallery pressure regulator of the engine according to the present invention.

도 4는 본 발명의 실시예에 따른 압력 조절용 밸브의 구성을 도시한 도면.4 is a view showing the configuration of a pressure regulating valve according to an embodiment of the present invention.

본 발명은 오일펌프로부터 엔진의 메인 갤러리로 제공되는 오일의 압력을 메인 갤러리측 압력과 연동되어 조절되도록 하여, 메인 갤러리로 제공되는 오일의 압력이 적정의 수준을 유지할 수 있도록 하는 엔진의 메인 갤러리 압력조절장치에 관 한 것이다.The present invention is to adjust the pressure of the oil provided from the oil pump to the main gallery of the engine in conjunction with the main gallery side pressure, the main gallery pressure of the engine to maintain the proper level of the pressure of the oil provided to the main gallery It is about the regulator.

일반적으로 엔진내 각종 윤활부위로 제공되는 오일의 유동경로는 다음과 같은 바, 즉 오일팬→오일펌프→오일쿨러→오일필터→메인 갤러리→엔진의 각 파트의 순서로 이루어진다.In general, the flow path of oil provided to various lubrication parts in the engine is as follows: in order of oil pan → oil pump → oil cooler → oil filter → main gallery → engine.

이 경우, 가솔린 엔진이나 승용디젤 엔진에 있어 오일의 유동경로는 도 1에 도시된 바와 같이, 오일팬(10)→오일펌프(12)→압력 조절용 밸브(20)→오일쿨러(14)→오일필터(16)→메인 갤러리(18)의 순서로 이루어진다.In this case, in the gasoline engine or the diesel engine, the flow path of the oil is as shown in FIG. 1, the oil pan 10 → oil pump 12 → pressure regulating valve 20 → oil cooler 14 → oil. The filter 16 is made in the order of the main gallery 18.

또한, 상용디젤 엔진에 있어 오일의 유동경로는 도 2에 도시된 바와 같이, 오일팬(10)→오일펌프(12)→오일쿨러(14)→오일필터(16)→압력 조절용 밸브(20)→메인 갤러리(18)의 순서로 이루어진다.In addition, the flow path of oil in a commercial diesel engine is as shown in FIG. 2, and the oil pan 10 → oil pump 12 → oil cooler 14 → oil filter 16 → pressure regulating valve 20. → it takes place in the order of the main gallery 18.

그런데, 상기와 같은 오일의 유동경로에 있어서, 상기 메인 갤러리(18)로부터 들어오는 오일의 압력은 엔진의 회전수가 중속 이상에서는 과도하게 높기 때문에, 엔진의 각 파트에 대한 윤활에 악영향을 미치게 된다.By the way, in the oil flow path as described above, since the pressure of the oil coming from the main gallery 18 is excessively high above the medium speed, the lubrication of each part of the engine is adversely affected.

따라서, 엔진의 각 파트에 정상적인 윤활을 도모할 수 있는 적정압이 상기 메인 갤러리(18)로 제공되어야 하는 데, 이러한 기능을 수행하는 것이 상기 압력 조절용 밸브(20)인 것이다.Therefore, an appropriate pressure that can achieve normal lubrication of each part of the engine should be provided to the main gallery 18. It is the pressure regulating valve 20 that performs this function.

즉, 상기 압력 조절용 밸브(20)는 오일의 유동경로상에 설치되어, 설정압 이상의 압력이 메인 갤러리(18)에 공급될 경우, 이를 중간에서 차단하고 잉여의 오일을 오일팬(10)으로 드레인시킴으로써, 상기 메인 갤러리(18)로 제공되는 오일의 압력을 설정압 이하의 수준으로 유지시킬 수 있게 된다.That is, the pressure control valve 20 is installed on the flow path of the oil, when a pressure above the set pressure is supplied to the main gallery 18, it is blocked in the middle and drain the excess oil to the oil pan (10) In this way, the pressure of the oil provided to the main gallery 18 can be maintained at a level below the set pressure.

그러나, 종래 가솔린 엔진과 승용디젤 엔진의 경우에는 상기 압력 조절용 밸브(20)를 오일펌프(12)와 오일쿨러(14) 사이에 위치시켜 상기 오일쿨러(14)와 오일필터(16)내로 들어가는 오일량이 조절되므로, 엔진의 각 파트에 적정량의 오일만이 오일쿨러(14)나 오일필터(16)로 제공되어 엔진의 성능이나 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 내구성 측면에서 유리하지만, 이 경우에는 오일쿨러(14)나 오일필터(16)를 경유할 때 발생하는 차압을 감안하여 압력 조절용 밸브(20)에 대한 설정압을 조절할 수 밖에 없으므로, 엔진의 각 파트에 위치하는 베어링부위의 마모나, 엔진의 냉시동시에는 상기 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 과도한 차압의 발생으로 인하여 메인 갤러리(18)의 적정압을 유지하기 어렵게 되는 문제가 있었고, 엔진의 각 파트의 베어링부위의 마모와 엔진의 냉시동시 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 과도한 차압까지 고려하여 상기 압력 조절용 밸브(20)의 설정압을 조정하게 되면, 엔진의 정상조건에서 메인 갤러리(18)의 압력이 과도하게 높아지게 되는 문제가 있게 된다.However, in the case of a conventional gasoline engine and a passenger diesel engine, the pressure regulating valve 20 is positioned between the oil pump 12 and the oil cooler 14 so that the oil enters into the oil cooler 14 and the oil filter 16. Since the amount is controlled, only an appropriate amount of oil is provided to each part of the engine to the oil cooler 14 or the oil filter 16, so that the performance of the engine or the oil pump 12 and the oil cooler 14 and the oil filter 16 In terms of durability, but in this case, it is necessary to adjust the set pressure for the pressure regulating valve 20 in consideration of the differential pressure generated when passing through the oil cooler 14 or the oil filter 16, so that each part of the engine Maintaining the proper pressure of the main gallery 18 due to the occurrence of excessive differential pressure between the oil pump 12, the oil cooler 14 and the oil filter 16 during wear of the bearing portion located in the engine or cold start of the engine. There was a problem that became difficult, and each part of the engine When the set pressure of the pressure regulating valve 20 is adjusted in consideration of wear of the bearing portion of the engine and excessive differential pressure of the oil pump 12, the oil cooler 14, and the oil filter 16 during cold start of the engine, There is a problem that the pressure of the main gallery 18 becomes excessively high under normal conditions.

또한, 상용디젤 엔진의 경우에는 압력 조절용 밸브(20)가 메인 갤러리(18)의 전단에 위치하기 때문에, 엔진의 각 파트의 베어링부위의 마모, 엔진의 냉시동시 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 과도한 차압 등을 고려한 메인 갤러리(18)에 대한 적정 압력의 설정은 가능하지만, 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)로 들어가는 오일의 양이 적정수준의 유량 보다 많기 때문에, 엔진의 동력 성능이나 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 내구력 측면에서는 불리하게 된다.In addition, in the case of a commercial diesel engine, since the pressure adjusting valve 20 is located at the front end of the main gallery 18, wear of the bearing part of each part of the engine, oil pump 12 and oil cooler during cold start of the engine ( 14) and an appropriate pressure can be set for the main gallery 18 in consideration of excessive differential pressure of the oil filter 16, but the oil entering the oil pump 12 and the oil cooler 14 and the oil filter 16 can be Since the amount is larger than the appropriate flow rate, it is disadvantageous in terms of power performance of the engine and durability of the oil pump 12, the oil cooler 14, and the oil filter 16.

이에 본 발명은 상기와 같은 제반 사안들을 해소하기 위해 안출된 것으로, 오일펌프로부터 엔진의 메인 갤러리로 제공되는 오일의 압력을 메인 갤러리측에서 요구되는 압력과 연동시켜 조절함으로써, 메인 갤러리로 제공되는 오일의 압력이 최적의 수준으로 유지될 수 있도록 하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned issues, by adjusting the pressure of the oil provided from the oil pump to the main gallery of the engine in conjunction with the pressure required by the main gallery side, the oil provided to the main gallery The purpose is to ensure that the pressure of the is maintained at an optimum level.

상기와 같은 목적을 달성하기 위한 본 발명은, 오일팬에 저장된 오일을 가압하는 오일펌프로부터 제공되는 오일을 오일쿨러와 오일필터를 거쳐 메인 갤러리로 공급하여 엔진의 각 파트에 대한 윤활을 시행하는 오일의 유동경로중에서, 상기 오일펌프와 상기 오일쿨러 사이에 상기 메인 갤러리내 압력을 신호압으로 제공받아, 상기 오일펌프로부터 상기 오일쿨러로 제공되는 오일의 압력이 설정치를 초과하면 상기 오일팬으로 오일을 드레인시키고, 설정치 이하이면 상기 오일쿨러로 오일을 공급하는 압력 조절용 밸브를 설치하여 구성되는 것을 특징으로 한다.The present invention for achieving the above object, the oil supplied from the oil pump for pressurizing the oil stored in the oil pan through the oil cooler and the oil filter to the main gallery to perform lubrication for each part of the engine In the flow path of the oil pressure is supplied between the oil pump and the oil cooler in the main gallery as a signal pressure, when the pressure of the oil supplied from the oil pump to the oil cooler exceeds a set value to the oil pan It is characterized in that it is configured to install a pressure regulating valve for supplying oil to the oil cooler if the drain is less than the set value.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도면에 도시된 바와 같이, 오일팬(10)에 저장된 오일은 오일펌프(12)의 작동에 따라 토출되고, 상기 오일펌프(12)로부터 공급되는 오일의 압력은 압력 조절용 밸브(20)에 의해 적정의 수준으로 조절되며, 상기 압력 조절용 밸브(20)로부터 압력의 조정이 이루어진 오일은 오일쿨러(14)와 오일필터(16)를 거쳐 메인 갤러리(18)로 공급되어 엔진의 각 파트로 제공될 수 있도록 구성된다. As shown in the figure, the oil stored in the oil pan 10 is discharged according to the operation of the oil pump 12, the pressure of the oil supplied from the oil pump 12 is the pressure control valve 20 The oil is adjusted to a proper level, and the oil whose pressure is adjusted from the pressure adjusting valve 20 is supplied to the main gallery 18 through the oil cooler 14 and the oil filter 16 to each part of the engine. It is configured to be provided.

이 경우, 상기 오일쿨러(14)는 오일을 냉각시키는 기능을 하는 것이고, 상기 오일필터(16)는 오일중 포함된 이물질을 제거하는 기능을 하는 것이다.In this case, the oil cooler 14 serves to cool the oil, and the oil filter 16 serves to remove foreign substances contained in the oil.

한편, 상기 압력 조절용 밸브(20)는 상기 메인 갤러리(18)내 오일의 압력이 설정치를 초과하면, 상기 오일펌프(12)로부터 제공되는 오일을 상기 오일팬(10)으로 드레인시키고, 상기 메인 갤러리(18)내 오일의 압력이 설정치를 초과하지 않으면, 상기 오일펌프(12)로부터 제공되는 오일을 상기 오일쿨러(14)로 공급하도록 구성된다.Meanwhile, when the pressure of the oil in the main gallery 18 exceeds a set value, the pressure adjusting valve 20 drains the oil provided from the oil pump 12 to the oil pan 10, and the main gallery. If the pressure of the oil in 18 does not exceed the set value, the oil provided from the oil pump 12 is configured to be supplied to the oil cooler 14.

이를 위해, 상기 압력 조절용 밸브(20)는 상기 오일펌프(12)와 상기 오일쿨러(14) 사이에 형성된 오일의 유동관로(21)중에 분지되어 상기 오일팬(10)으로 연결된 드레인 관로(22)에 대한 개폐를 조절하도록 일단이 리턴 스프링(24)을 매개로 탄발지지되는 제1스풀(26)과, 상기 제1스풀(26)과 일체로 연결되고 상기 메인 갤러리(18)내 압력을 신호압으로 제공받는 압력실(30)내에 설치된 제2스풀(32)을 구비하고 있다.To this end, the pressure control valve 20 is branched in the flow passage 21 of oil formed between the oil pump 12 and the oil cooler 14, the drain conduit 22 connected to the oil pan (10) A first spool 26, one end of which is elastically supported through the return spring 24, to be integrally connected to the first spool 26 and to control the pressure in the main gallery 18 so as to adjust the opening and closing thereof. The 2nd spool 32 provided in the pressure chamber 30 provided with the said is provided.

따라서, 상기 오일펌프(12)의 구동에 의해 오일쿨러(14)와 오일필터(16)를 거쳐 메인 갤러리(18)로 제공되는 오일의 압력은 상기 압력 조절용 밸브(20)에 의해 항상 적정의 수준으로 유지될 수 있는 바, 특히 상기 압력 조절용 밸브(20)에서 메인 갤러리(18)로 제공되는 오일의 압력은, 메인 갤러리(18)내 압력을 신호압으로 제공받아 최적으로 조절될 수 있으므로, 종래 가솔린 엔진이나 승용디젤 엔진에서와 같이 오일쿨러(14)나 오일필터(16)를 경유할 때 발생하는 차압을 감안하여 압력 조절용 밸브(20)로부터 조압되는 압력을 임의대로 설정하지 않아도 된다.Therefore, the pressure of the oil provided to the main gallery 18 via the oil cooler 14 and the oil filter 16 by the operation of the oil pump 12 is always at an appropriate level by the pressure adjusting valve 20. In particular, the pressure of the oil provided to the main gallery 18 from the pressure adjusting valve 20 may be optimally adjusted by receiving the pressure in the main gallery 18 as a signal pressure. It is not necessary to arbitrarily set the pressure regulated from the pressure regulating valve 20 in consideration of the differential pressure generated when passing through the oil cooler 14 or the oil filter 16 as in a gasoline engine or a passenger diesel engine.

이 결과, 엔진의 각 파트에 위치하는 베어링부위의 마모나, 엔진의 냉시동시에 상기 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 과도한 차압의 발생으로 인하여 메인 갤러리(18)내 적정의 압력을 유지하기 어려웠던 문제를 해소할 수 있게 된다.As a result, the main gallery 18 may occur due to wear of bearing parts located in each part of the engine or excessive differential pressure of the oil pump 12, the oil cooler 14, and the oil filter 16 during cold start of the engine. I can solve the problem that was difficult to maintain my pressure.

또한, 종래 상용디젤 엔진에서와 같이 상기 압력 조절용 밸브(20)를 메인 갤러리(18)의 전단에 위치시키지 않아도 되므로, 엔진의 동력 성능이나 오일펌프(12)와 오일쿨러(14) 및 오일필터(16)의 내구력 측면에서는 불리하던 문제를 해소할 수 있게 된다.In addition, since the pressure control valve 20 does not have to be located at the front end of the main gallery 18 as in the conventional commercial diesel engine, the power performance of the engine, the oil pump 12, the oil cooler 14, and the oil filter ( In terms of durability, the disadvantages of 16 can be solved.

이상 설명한 바와 같이 본 발명에 따른 엔진의 메인 갤러리 압력조절장치에 의하면, 오일펌프로부터 오일쿨러와 오일필터를 거쳐 메인 갤러리로 제공되는 오일의 압력이 메인 갤러리내 압력을 신호압을 받아 적정의 공급압으로 조압할 수 있는 압력 조절용 밸브에 의해 조정될 수 있으므로, 메인 갤러리로 제공되는 압력을 최적화시킬 수 있게 된다.As described above, according to the main gallery pressure regulating device of the engine according to the present invention, the pressure of the oil provided from the oil pump to the main gallery via the oil cooler and the oil filter receives the signal pressure in the main gallery to supply an appropriate supply pressure It can be adjusted by a pressure control valve that can be adjusted to the pressure, it is possible to optimize the pressure provided to the main gallery.
