본 고안은 냉각수의 온도를 일정하게 하여 엔진의 정상적인 작동을 지속적으로 유지시키기 위한 써모스타트에 관한 것으로서, 특히 냉각수의 급격한 온도변화나, 충격에 써모스타트 피스톤이 이탈됨을 방지할 수 있도록한 써모스타트 피스톤의 이탈방지구조에 관한 것이다.The present invention relates to a thermostat for maintaining a constant temperature of the coolant to maintain normal engine operation. In particular, the thermostat piston prevents the thermostat piston from escaping due to a sudden change in temperature of the coolant or an impact. It relates to a structure for preventing departure.
주지된 바와같이 써모스타트는 엔진내의 냉각수온도변화에 따라, 엘레멘트 조립체(ELEMENT ASS'Y)의 피스톤 작동에 의한 밸브의 작동으로 냉각수를 이동시킨후, 라디에이터 등을 통하여 엔진내로 들어가 엔진을 냉각시킬 수 있도록 하는 것이다.As is well known, the thermostat may move into the engine through a radiator to cool the engine after moving the coolant by the operation of a valve by the piston of the element assembly according to the change of the coolant temperature in the engine. To ensure that
그러나, 종래의 써모스타트는 제 3 도 및 제 4 도에서와 같이 상측에 피스톤(52)이 설치되고, 내부에는 왁스가 내장된 엘레멘트조립체(51)를 플랜지(55)에 의해 부착되는 상부 스톱퍼(53)와, 하부케이스(54) 내부에 설치하되, 상기 엘레멘트조립체(51)중앙에는 스프링(57)이 설치된 상태로 밸브(56)를 설치하여 상,하부함실(58) (58')을 형성하고, 피스톤(52) 끝단은 상부스톱퍼(53) 중앙에 고정된 캡(59)의 요홈에 설치하였는바, 이는 엔진의 냉각수 온도가 급격히 변하거나, 외부로부터 갑작스러운 충격시 엘라멘트가 온도변화에 대한 순간적인 충격에 대한 대응력이 부족하고, 피스톤 또한 상부스톱퍼(53)의 요홈에 단순히 걸려져 있는 상태로 끼워져 있어 피스톤(52)의 상, 하동작시 이탈빈도가 높아 서모스타트의 오동작 또는 작동불능 상태가 되고, 엔진의 과열, 과냉 및 소착 등이 되는 문제점이 야기되었다.However, in the conventional thermostat, as shown in FIGS. 3 and 4, a piston 52 is installed on the upper side, and an upper stopper is attached to the element assembly 51 having wax embedded therein by a flange 55 ( 53) and the lower case 54, but the upper and lower chambers 58 and 58 'are formed by installing a valve 56 at the center of the element assembly 51 with the spring 57 installed. And, the end of the piston 52 is installed in the groove of the cap 59 fixed to the center of the upper stopper 53, which means that the coolant temperature of the engine is suddenly changed, or the element is suddenly changed in case of sudden impact from the outside. Insufficient responsiveness to instantaneous shock, and the piston is also simply caught in the groove of the upper stopper 53, so that the frequency of release of the piston 52 during the up and down movement of the piston 52 is high. It is in a state, and the engine is overheated and overcooled And sintering and the like have been caused.
본 고안은 상기한 종래의 제문제점 등을 해결하기 위하여 안출된 것으로서, 본 고안의 주된 목적으론, 써모스타트가 어떠한 냉각수 온도변화나 충격시에도 피스톤의 이탈 또는 위치변경됨을 방지하여 원활한 냉각수공급을 할 수 있도록 한 것이 그 특징이다.The present invention is devised to solve the above-mentioned problems, the main purpose of the present invention, the thermostat is to provide a smooth cooling water supply by preventing the displacement or position of the piston at any cooling water temperature change or impact It is a feature that makes it possible.
상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.
제 1 도는 본 고안이 적용된 써모스타트의 조립단면도이고, 제 2 도는 피스톤의 결합상태를 보인 본 고안의 요부발췌 단면도로서 도면에서와 같이 상측에 피스톤(2)이 설치되고, 내부에는 왁스가 내장된 엘레멘트조립체(1)를 플랜지(5)에 의해 부착되는 상부스톱퍼(3)와 하부케이스(4) 내부에 설치하되, 상기 엘레멘트조립체(1)의 중앙에는 스프링(7)이 설치된 상태로 밸브(6)를 설치하여, 상,하부함실(8) (8')을 형성한다.1 is an assembled cross-sectional view of a thermostat to which the present invention is applied, and FIG. 2 is a cross-sectional view of an essential part of the present invention showing a coupling state of a piston, and a piston (2) is installed at an upper side as shown in the drawing, and wax is embedded therein The element assembly (1) is installed inside the upper stopper (3) and the lower case (4) attached by the flange (5), and the valve (6) with the spring (7) installed in the center of the element assembly (1). ), Upper and lower compartments 8 and 8 'are formed.
그리고 상부스톱퍼(3)의 중앙에는 설치공(10)이 관통된 캡(9)을 설치하여, 상기 피스톤(2)을 관통삽입한 후 외측에서 끝단을 코킹 또는 압착하여 구성된 것이다.And the center of the upper stopper (3) is installed by installing the cap (9) through which the installation hole 10 is penetrated, it is configured by caulking or crimping the end from the outside after inserting the piston (2).
이와같이 구성된 본 고안은 엔진운전시 냉각수온도를 일정하게 하여 엔진의 정상적인 작동을 지속적으로 유지시키기 위하여 장착되는 써모스타트는 엔진내의 온도가 상승된 냉각수가 일정한 온도가 유지되면 상부스톱퍼(3)와 하부케이스(4)내에 설치된 엘레멘트조립체(1)내에 있는 왁스가 팽창하여 부피가 상승되어 피스톤(2)을 밀게된다.The present invention is constructed in such a way that the thermostat, which is installed to maintain a constant coolant temperature during engine operation and maintains the normal operation of the engine, has an upper stopper (3) and a lower case when the coolant whose temperature rises in the engine is maintained at a constant temperature. The wax in the element assembly (1) installed in (4) expands and the volume is raised to push the piston (2).
그리고 밀려진 피스톤(2)은 상부스톱퍼(3)중앙에 설치된 캡(9)에 정지되어 계속 전진하려는 힘을 갖는다. 그러면 캡(9)에 의해 피스톤(2)은 정지되고 엘레멘트조립체(1)는 후퇴하게 되는데, 이때 엘레멘트조립체(1)중앙에 설치되어 있는 밸브(6)가 동시에 후퇴하여 하부함실(8')에 있던 냉각수가 플랜지(5)와, 밸브(6)사이가 이격되어 화살표방향으로 상부함실(8)로 이동된다.And the pushed piston (2) is stopped in the cap (9) installed in the center of the upper stopper (3) has the force to continue to advance. Then, the piston 2 is stopped by the cap 9 and the element assembly 1 is retracted. At this time, the valve 6 installed at the center of the element assembly 1 retreats at the same time to the lower compartment 8 '. The existing coolant is moved between the flange 5 and the valve 6 to move to the upper compartment 8 in the direction of the arrow.
상기 이동된 냉각수는 라디에이터 등 냉각계통을 통하여 다시 냉각수는 엔진내로 들어가게 되어있으나, 이때 스프링(7)을 밀어주는 장력보다 냉각수의 급격한 온도변화 또는 냉각수가 플랜지(5)와, 밸브(6)사이가 이격되어 화살표방향으로 상부함실(8)로 이동된다.The coolant is moved back into the engine through a cooling system such as a radiator, but at this time, a sudden change in temperature of the coolant or a coolant between the flange 5 and the valve 6 is greater than the tension for pushing the spring 7. It is spaced apart and moved to the upper compartment 8 in the direction of the arrow.
상기 이동된 냉각수는 라디에이터 등 냉각계통을 통하여 다시 냉각수는 엔진내로 들어가게 되어있으나, 이때 스프링(7)을 밀어주는 장력보다 냉각수의 급격한 온도변화 또는 외부의 충격등의 힘이 더 커질때에도 피스톤(2)이 단차되게 캡(9)의 설치공(10)에 견고히 끼워진 상태로 코킹 또는 압착고정되어 있어 어떠한 경우라도 이탈되지 않게 되는 것이다.The coolant is moved back into the engine through a cooling system such as a radiator, but the piston (2) even when a force such as a sudden temperature change or external impact of the coolant is greater than the tension for pushing the spring (7). This step is caulking or crimping in a state that is firmly fitted in the installation hole 10 of the cap 9, so that in any case will not be separated.
이상 설명한 바와같이 써모스타트의 엘레멘트조립체와 일체로 된 피스톤을 상부스톱퍼 중앙에 설치된 캡에 관통설치하여 코킹 또는 압착하므로서 피스톤의 이탈이 전혀 없어, 써모스타트의 오동작 또는 작동불능이 전혀 없는 매우 유용한 고안이다.As described above, the piston integrated with the element assembly of the thermostat is penetrated through the cap installed at the center of the upper stopper, and is caulked or crimped. .
