Abstract
estrutura de alimentação de óleo lubrificante de compressor do tipo de palhetas. é provida uma estrutura de alimentação de óleo lubrificante de um compressor do tipo de palhetas que pode alimentar com uma quantidade suficiente de óleo lubrificante também um mancal de deslizamento distante de uma câmara de reservatório de óleo fazendo uso de câmaras de contrapressão formadas em cilindros tendo a estrutura existente assim realizando apenas uma ligeira mudança de um formato de uma porção em recesso formada em superfícies de extremidade lateral de cilindro de blocos que fecham o cilindro. na estrutura de alimentação de óleo lubrificante de um compressor do tipo de palhetas 1 de acordo com a presente invenção, formatos e posições de primeira e segunda porções em recesso 36,37 formadas em blocos 5,6 são ajustados tal que, com uma passagem de alimentação de óleo lubrificante onde óleo lubrificante entra em uma câmara de contrapressão 10 a partir de uma câmara de reservatório de óleo 19 através de uma primeira porção em recesso 36 e, depois disso, alcança um segundo mancal 12 a partir da câmara de contrapressão 10 através de uma segunda porção em recesso 37, a primeira porção em recesso 16 e a câmara de contrapressão 10 ficam em comunicação uma com a outra de modo que óleo lubrificante é alimentado na câmara de contrapressão 10 a partir da câmara de reservatório de óleo 19 durante um período onde a volume de curso de uma palheta 9 é aumentado de modo que pressão na câmara de contrapressão 10 é relativamente reduzida, e a segunda porção em recesso 36 e a câmara de contrapressão 10 ficam em comunicação uma com a outra de modo que óleo lubrificante na câmara de contrapressão 10 é liberado e é alimentado no segundo mancal 12 durante um período onde o volume de curso da palheta 9 é reduzido de modo que pressão na câmara de contrapressão 10 é relativamente aumentada.vane type compressor lubricating oil supply frame. There is provided a lubricating oil supply structure of a vane type compressor which can feed a sufficient amount of lubricating oil also a sliding bearing away from an oil reservoir chamber making use of cylinder formed back pressure chambers having the existing structure thus performing only a slight change in shape of a recessed portion formed on cylinder end-end surfaces of blocks that close the cylinder. in the lubricating oil supply structure of a vane type compressor 1 according to the present invention, shapes and positions of first and second recessed portions 36,37 formed into blocks 5,6 are adjusted such that with a passage of lubricating oil feed where lubricating oil enters a back pressure chamber 10 from an oil reservoir chamber 19 through a first recessed portion 36 and thereafter reaches a second bearing 12 from back pressure chamber 10 through of a second recessed portion 37, the first recessed portion 16 and the back pressure chamber 10 are in communication with each other so that lubricating oil is fed into the back pressure chamber 10 from the oil reservoir chamber 19 for a period where the stroke volume of a vane 9 is increased so that pressure in the back pressure chamber 10 is relatively reduced, and the second the recessed portion 36 and the backpressure chamber 10 are in communication with each other so that lubricating oil in the backpressure chamber 10 is released and fed into the second bearing 12 during a period where the stroke volume of the vane 9 is reduced. so that pressure in the back pressure chamber 10 is relatively increased.
