[종래기술][Private Technology]

일반적으로 워터펌프에는 원심펌프가 사용되는데, 이 원심펌프는 중앙의 임펠러의 회전에 따라 물을 원심력으로 외부로 보내주는 펌프작용을 하는 것으로 회전은 크랭크축 풀리에 의해 브이벨트로 전달되며, 회전속도는 크랭크 축의 1,2-1,6배 정도이다.In general, a centrifugal pump is used for a water pump. The centrifugal pump acts as a pump that sends water to the outside as a centrifugal force according to the rotation of the central impeller. Is about 1,2-1,6 times the crankshaft.

또한 상기한 워터펌프에 팬이 장치되어 있다. 이 임펠러는 6장정도의 날개를 가지고 있으며 로터축에 압입되어 케이싱내에서 회전하게 되어 있다.In addition, a fan is installed in the water pump. This impeller has about six wings and is pressed into the rotor shaft to rotate in the casing.

상기한 케이싱과 케이싱과 로터축 사이에는 시일 고무, 스러스트 플레이트 스프링 등으로 이루어지는 시일 기구가 설치되어 있으며, 물의 누출을 방지하게 되어 있다.A sealing mechanism made of a seal rubber, a thrust plate spring, or the like is provided between the casing, the casing, and the rotor shaft, to prevent leakage of water.

상기한 종래기술은 엔진이 뜨거운 상태에서 워터펌프의 기능은 정상이지만 엔진의 냉각수온에 전혀 관계없이 엔진이 기동할때 무조건 냉각수를 퍼올리기만하면 냉각상태인 엔진에는 도움이 되질 못하고, 연소과정에서 유해 배기가스의 배출이 이루어지는 등의 문제가 있다.The above-mentioned conventional technique is normal in the function of the water pump in the hot state of the engine, but irrespective of the cooling water temperature of the engine at all when the engine unconditionally pumping the coolant is not helpful to the cooled state, harmful to the combustion process There is a problem such as discharge of exhaust gas.

또한 상기한 바와 같이 엔진이 냉각된 상태에서 가동하게 되면 뜨거운 상태에서 보다 유해가스의 배출량이 증가하게 되고, 또한 연료의 소모량이 많아짐은 물론 냉각된 구동부위의 마찰저항이 커져서 열효율이 저하되며, 각부위의 마모가 발생함과, 아울러 동력의 손실이 발생하는 문제점이 있다.In addition, as described above, when the engine is operated in a cooled state, emissions of harmful gases are increased in a hot state, and fuel consumption is increased, as well as the frictional resistance of the cooled driving portion is increased, thereby reducing thermal efficiency. Abrasion of the site occurs, and there is a problem that the loss of power occurs.

이를 실현하기 위한 본 고안은 워터펌프의 회전축에 형성된 스플라인기어와 슬라이딩 결합하도록 설치된 임펠러와, 상기 임펠러가 워터펌프의 공간부내로 유입되는 냉각수의 수온에 따라 임펠러를 좌,우 슬라이딩 시키도록 하우징에 설치된 가변조절기를 포함하여 이루어지는 워터펌프의 임펠러 가변구조를 특징으로 한다.The present invention for realizing this is installed in the housing so as to slide the impeller left and right according to the impeller installed to slid with the spline gear formed on the rotating shaft of the water pump and the coolant flows into the space portion of the water pump Characterized in that the impeller variable structure of the water pump comprising a variable regulator.

상기한 가변조절기는 브레이드가 형성된 임펠러와 후면에서 푸쉬작용이 이루어지도록 내마모 재질로 형성된 푸쉬부재와, 이 푸쉬부재를 밀어내거나 후진시키기 위하여 냉각수온에 따라 수축과 팽창작용을 하는 왁스와, 이 왁스를 게재하여 내장하면서 푸쉬부재가 슬라이드하게 삽입되면서 워터펌프의 하우징에 돌출 형성되는 실린더를 포함하여 이루어지는 워터펌프의 임펠러 가변구조를 제공하는데 있다.The variable regulator includes a push member formed of an abrasion-resistant material to achieve a push action on the back of the impeller and the braid formed therein, waxes that contract and expand according to the cooling water temperature to push or push the push member backwards, and the wax It is to provide a variable structure of the impeller of the water pump comprising a cylinder which is formed to protrude in the housing of the water pump while being inserted to slide while the built-in.

상기한 본 고안은 워터펌프의 작용에 의하여 유입되는 냉각수의 수온에 따라 가변조절기내의 왁스가 수축과 팽창을 하므로서 실린더내에서 푸쉬부재를 밀어내게 되거나 후진하도록 하므로서 임펠러의 좌,우 이동이 가변적으로 조절되어 냉각수가 고온일때는 압송량을 증대시키고, 저온일때는 압송량이 저감되므로서 동력의 낭비없이 작동하도록 한다.According to the present invention, according to the water temperature of the cooling water introduced by the action of the water pump, the wax in the variable controller contracts and expands to push or push the push member in the cylinder, thereby controlling the left and right movement of the impeller variably. Therefore, when the coolant is hot, the amount of pressure is increased, and when the temperature of the coolant is low, the amount of pressure is reduced to operate without wasting power.

[실시예]EXAMPLE

제1도는 본 고안에 따른 워터펌프의 임펠러 가변구조를 도시한 측단면도이고, 제2도는 본 고안에 따른 워터펌프의 가변 조절기를 도시한 도면으로, 부호(1)은 워터펌프를 지칭한다.1 is a side cross-sectional view showing an impeller variable structure of the water pump according to the present invention, Figure 2 is a view showing a variable regulator of the water pump according to the present invention, reference numeral 1 denotes a water pump.

상기한 워터펌프(1)는 회전축(2)에 스플라인기어(3)를 형성하여 슬라이딩 결합된 임펠러(4)를 설치하고 있다.The water pump 1 has a spline gear 3 formed on the rotating shaft 2 to install an impeller 4 slidingly coupled.

상기한 임펠러(4)가 워터펌프의 공간부(5)내로 유입되는 냉각수의 수온에 따라 임펠러(4)를 좌,우 슬라이딩 시키도록 하우징(6)에 가변조절기(7)를 설치하고 있다.A variable regulator 7 is installed in the housing 6 so that the impeller 4 slides the impeller 4 left and right according to the water temperature of the coolant flowing into the space 5 of the water pump.

상기한 가변조절기(7)는 브레이드(8)가 형성된 임펠러(4)의 후면에서 푸쉬작용이 이루어지도록 하면서 내마모 재질로 형성된 푸쉬부재(9)를 설치하고 있다.The variable regulator 7 is provided with a push member 9 formed of a wear-resistant material while the push action is made at the rear of the impeller 4 formed with the braid 8.

상기한 푸쉬부재(9)는 밀어내거나 후진시키기 위하여 냉각수온에 따라 수축과 팽창작용을 하는 왁스(10)와, 이 왁스를 게재하여 내장하면서 푸쉬부재(9)가 슬라이드하도록 삽입되게 워터펌프(1)의 하우징(6)에 돌출 형성되는 실린더(11)를 포함하여 이루어져 있다.The push member 9 includes a wax 10 that contracts and expands according to the cooling water temperature to push or retract the push member 9, and the water pump 1 to be inserted so that the push member 9 slides while the wax member is placed and embedded therein. It comprises a cylinder (11) protruding from the housing (6) of.

이와 같이 이루어지는 본 고안의 작용은 제3도에 도시한 바와 같이 워터펌프(1)의 작용에 의하여 유입되는 냉각수의 수온을 감지하여 왁스(10)가 수축과 팽창을 하므로서 실린더(11)내에서 푸쉬부재를 밀어내거나 후진하도록 한다.The operation of the present invention made as described above is pushed in the cylinder 11 as the wax 10 contracts and expands by sensing the water temperature of the cooling water introduced by the action of the water pump 1 as shown in FIG. Push the member out or back it up.

상기한 실린더(11)에서 가변조절기(7)의 푸쉬부재(9)가 전진 또는 후진하므로서 임펠러(4)의 좌,우 이동한다.In the cylinder 11, the push member 9 of the variable regulator 7 moves forward or backward and moves left and right of the impeller 4.

상기한 임펠러(4)가 좌,우 슬라이딩하여 회전하므로서 냉각수의 압송량은 증감하게 되고, 이 임펠러(4)의 좌,우 슬라이딩이 임펠러(4)의 회전이 조절되도록 브레이드(8)가 형성된 회전판(12)에는 균형을 잡아주는 조절공(13)이 형성되어 있다.As the impeller 4 rotates left and right, the amount of cooling water is increased and the left and right sliding of the impeller 4 rotates the rotating plate on which the braid 8 is formed so that the rotation of the impeller 4 is controlled. 12, the adjustment hole 13 to balance is formed.

이에 따라 임펠러(4)의 블레이드(8)의 끝단과 하우징(6)의 A부분과의 간극(S)이 조정되어 냉각수가 고온일때는 압송량을 증대시키고, 이때 간극(S)은 작아진다.As a result, the gap S between the end of the blade 8 of the impeller 4 and the A portion of the housing 6 is adjusted to increase the feeding amount when the cooling water is at a high temperature, and the gap S becomes small at this time.

그리고 냉각수가 저온일때는 압송량을 저감하여야 하므로서 간극(S)의 틈새는 크게 되어 압송량의 감소가 이루어져 동력의 낭비없이 작동하도록 한다.In addition, when the cooling water is low temperature, the amount of feeding should be reduced, so that the gap (S) has a large gap, thereby reducing the amount of feeding and operating without wasting power.

이러한 본 고안은 임펠러에 브레이드가 형성된 배면 하우징에 수온에 따라 팽창과 수축하는 왁스를 내장한 가변조절기를 설치하므로서 냉각수온에 따라 임펠러가 좌,우 이동을 하여 냉각수의 압송량이 조절됨으로서 동력의 낭비를 해소하는 유용한 고안이다.The present invention installs a variable regulator containing a wax that expands and contracts according to the water temperature in the rear housing in which the braid is formed on the impeller, and the impeller moves left and right according to the cooling water temperature, thereby adjusting the amount of cooling water to be used to reduce the waste of power. It is a useful design to solve.
