Description

자동차 압축기용 윤활유확인창{Sight glass of compressor for vehicle}Lubricant confirmation window for automobile compressors {Sight glass of compressor for vehicle}

본 발명은 자동차 압축기용 윤활유확인창에 관한 것으로서 더욱 상세하게는 압축기 내부에 주입되는 윤활유의 유,무를 시각적으로 확인할 수 있도록 한 윤활유확인창의 제공에 관한 것이다.The present invention relates to a lubricant confirmation window for an automobile compressor, and more particularly, to the provision of a lubricant confirmation window for visually confirming the presence or absence of lubricant injected into the compressor.

자동차용 압축기는 하절기와 같이 외부온도가 높을 때 실내온도의 저하를 목적으로 냉매의 증발잠열을 이용하여 주위냉기를 냉각하여 열교환함으로서 실내온도를 떨어뜨리는 에어컨시스템에 적용되는 하나의 부품이다.Automotive compressor is a component that is applied to the air conditioner system to lower the indoor temperature by cooling the heat around the ambient air using the latent heat of evaporation for the purpose of lowering the indoor temperature when the outside temperature is high in the summer.

상기와 같은 에어컨시스템은 압축기, 컨덴서, 리시버드라이어, 팽창밸브, 증발기로 구성되며, 이 가운데 증발된 냉매의 압축에 필요한 냉매압축기는 피스톤의 왕복운동을 이용하여 냉매를 압축하게 된다.The air conditioner system as described above is composed of a compressor, a condenser, a receiver dryer, an expansion valve, and an evaporator, and a refrigerant compressor necessary for compressing the vaporized refrigerant compresses the refrigerant using a reciprocating motion of the piston.

특히 버스와 같이 대용량의 다기통 압축기는 고정을 위한 브라켓을 하단에 일체로 가지는 실린더블럭이 구비되고, 상기 실린더블럭의 내부에는 냉매압축을 위한 피스톤이 왕복운동할 수 있도록 실린더라이너로 유지되는 실린더가 형성된다.In particular, a large-capacity multi-cylinder compressor, such as a bus, is provided with a cylinder block having a bracket for fixing at the bottom, and a cylinder held by a cylinder liner to reciprocate the piston for refrigerant compression inside the cylinder block. Is formed.

상기 실린더에는 피스톤이 내장되어 실린더의 상방에서 실린더커버로 마감되는 밸브어셈블리를 통하여 압축된 냉매를 배출하고 압축할 냉매를 유입하게 된다.The cylinder has a built-in piston to discharge the compressed refrigerant through the valve assembly closed with the cylinder cover from above the cylinder and introduce the refrigerant to be compressed.

상기 피스톤은 실린더블럭의 하방에 설치되는 크랭크샤프트와 커넥팅로드로 연결하고, 상기 크랭크샤프트의 일단에는 엔진으로 부터 동력을 전달받고, 동력절환을 위한 수단으로 클러치를 가지는 풀리를 고정한다.The piston is connected to a crankshaft and a connecting rod installed below the cylinder block, and one end of the crankshaft receives power from the engine and fixes a pulley having a clutch as a means for power switching.

상기 크랭크샤프트가 위치하는 실린더블럭의 저면에는 크랭크샤프트와 커넥팅로드의 원활한 작동과 고열의 냉각과 소착방지를 위한 윤활유를 충진할 수 있는 오일챔버가 일체로 구비되는 구성이다.The bottom surface of the cylinder block in which the crankshaft is located is integrally provided with an oil chamber capable of filling the lubricating oil for smooth operation of the crankshaft and the connecting rod and cooling of high heat and preventing seizure.

종래의 압축기(1)는 도 5에 도시된 바와같이,Conventional compressor 1 is shown in Figure 5,

오일챔버를 일체로 가지는 실린더블럭(2)의 어느 위치에도 오일챔버 상의 오일이 충진된 상태나 오일의 양을 시각적으로 확인할 수 있는 수단이 강구되지 않은 관계로 윤활유가 주입되었는지의 여부를 쉽게 파악할 수 없게된다.At any position of the cylinder block 2 having the oil chamber integrally, it is easy to determine whether the lubricating oil has been injected since no state of filling the oil on the oil chamber or a means for visually checking the amount of oil is not taken. There will be no.

특히, 조립과정이나 실차 장착된 상태에서는 윤활유의 확인없이 작동할 경우 압축작동을 위한 크랭크샤프트나 커넥팅로드와 같은 부품의 손상이 우려되고, 작동시 발생하는 고열의 냉각이 어려워 압축기 자체가 소착되어 작동불능상태에 이르게 되는 등 압축기의 성능과 내구성에 치명적인 악영향을 주게되고 사용자들에게는 상당한 불편을 초래하는 원인을 제공한다.Particularly, if the assembly process or the actual vehicle is installed without the check of lubricating oil, the parts such as the crankshaft or connecting rod for the compression operation may be damaged, and the compressor itself is sintered due to the difficulty of cooling the high temperature generated during operation. This can cause a fatal adverse effect on the performance and durability of the compressor, such as incapacity, and cause significant inconvenience to users.

이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명한 것으로서 실린더블럭내에 윤활유가 충진되었는지와 충진된 윤활유의 양을 시각적으로 확인할 수 있는 윤활유확인창을 일측 또는 양측으로 구비하여 압축기의 성능과 품질향상에 기여하고 사용자들의 편익향상에 기여할 수 있도록 하는 것을 목적으로 한다.Therefore, the present invention has been invented to solve the problems described above, and has a lubricant check window on one side or both sides that visually checks whether the lubricant is filled in the cylinder block and the amount of the lubricant filled, thereby improving the performance and quality of the compressor. It aims to contribute to and contribute to the benefit of users.

The cylinder is formed so that it is held by the cylinder liner.

상기 실린더에는 피스톤이 내장되어 실린더의 상방에서 실린더커버로 마감되는 밸브어셈블리(33)를 통하여 압축된 냉매를 배출하고 압축할 냉매를 유입하게 된다.The cylinder has a built-in piston so as to discharge the compressed refrigerant through the valve assembly 33 which is closed with the cylinder cover from above the cylinder and the refrigerant to be compressed is introduced.

상기 피스톤은 실린더블럭의 하방에 설치되는 크랭크샤프트와 커넥팅로드로 연결하고, 상기 크랭크샤프트의 일단에는 엔진으로 부터 동력을 전달받고, 동력절환을 위한 수단으로 클러치를 가지는 풀리(34)를 고정한다.The piston is connected to a crankshaft and a connecting rod installed below the cylinder block, and one end of the crankshaft receives power from the engine and fixes a pulley 34 having a clutch as a means for power switching.

상기 크랭크샤프트가 위치하는 실린더블럭(32)의 저면에는 크랭크샤프트와 커넥팅로드의 원활한 작동과 고열의 냉각과 소착방지를 위한 윤활유를 충진할 수 있는 오일챔버가 일체로 구비되는 구성이다.The bottom surface of the cylinder block 32 in which the crankshaft is located is integrally provided with an oil chamber capable of filling the lubricating oil for smooth operation of the crankshaft and the connecting rod and cooling of high heat and preventing seizure.

본 발명에서는 상기 실린더블럭(32)의 일측 또는 양측에 오일챔버에 윤활유가 충진되어 있는지와 충진된 윤활유의 양을 시각적으로 확인할 수 있는 윤활유확인창(40)을 구비한다.In the present invention, one or both sides of the cylinder block 32 is provided with a lubricating oil confirmation window 40 that can visually check whether the lubricating oil is filled in the oil chamber and the amount of the lubricating oil filled.
