Abstract
"COPO DE FILTRO E MéTODO PARA A FABRICAçãO DO MESMO".Antecedentes da Invenção.Referência Remissiva a Pedida de Patente Relacionado.O presente pedido de patente reivindica o benefício do pedido de patente de invenção norte-americano provisório No. de Série 60/016.724, depositado em 2 de maio de 1996. Campo da Invenção A presente invenção refere-se a um copo de filtro roscado laminado para ser usado com filtros de média pressão. Descrição da Técnica Anterior Os filtros de média pressão tais como aqueles usados em sistemas hidráulicos a óleo para acionadores hidrostáticos devem suportar pressões maiores do que 28,12 Kg/cm2 (400 libras por polegada quadrada). Além disso, os mesmos são submetidos a aplicações cíclicas ou repetidas de pressão. Os filtros de média pressão convencionais incluem um recipiente ou copo de metal tipicamente feito de aço e um elemento de filtro armazenado no interior do copo. O copo é fixado a uma coluna de filtro a qual está em comunicação de fluido com um conduto através do qual passa o fluído hidráulico. Tais disposições de copo e elemento de filtro são fabricados como uma unidade única. A extremidade aberta do recipiente é formada com roscas para acoplamento com a coluna de filtro. Tais filtros são conhecidos no estado da técnica como "filtros de encaixe por rosca". O copo integral tendo em seu interior o elemento de filtro é rosqueado sobre a coluna de filtro e fica então em comunicação de fluido com o conduto.Quando o elemento de filtro se contamina devido ao uso e atinge o fim de sua vida útil, todo o conjunto de filtro, incluindo o elemento de filtro e o copo, são removidos da coluna."COPO DE FILTRO E MéTODO PARA A FABRICAçãO DO MESMO"A presente invenção se refere a um copo de filtro (8). O copo de filtro (8) inclui um recipiente alongado tendo uma extremidade aberta (16), uma extremidade fechada e uma parede tendo uma superfície exterior (26), a superfície exterior tendo uma pluralidade de roscas laminadas (24). A superfície exterior (26) inclui uma porção não roscada (28) situada entre a extremidade aberta (16) e a pluralidade de roscas laminadas (24). O copo de filtro (8) é de preferência feito de aço e é produzido em um processo que inclui as etapas de: 1)estampagem profunda do recipiente alongado, e 2) laminação das roscas na superfície exterior do recipiente."FILTER CUP AND METHOD FOR MANUFACTURING THE SAME". Background of the Invention. Referenced Reference to Related Patent Application. This patent application claims the benefit of the provisional North American Patent Application Serial No. 60 / 016,724 , filed on May 2, 1996. Field of the Invention The present invention relates to a laminated threaded filter cup for use with medium pressure filters. Description of the Prior Art Medium pressure filters such as those used in hydraulic oil systems for hydrostatic actuators must withstand pressures greater than 28.12 Kg / cm2 (400 pounds per square inch). In addition, they are subjected to cyclical or repeated pressure applications. Conventional medium pressure filters include a metal container or cup typically made of steel and a filter element stored inside the cup. The cup is attached to a filter column which is in fluid communication with a conduit through which the hydraulic fluid passes. Such cup and filter element arrangements are manufactured as a single unit. The open end of the container is formed with threads for coupling with the filter column. Such filters are known in the art as "screw-in filters". The integral cup with the filter element inside is screwed onto the filter column and is then in fluid communication with the duct. When the filter element becomes contaminated due to use and reaches the end of its life, the entire filter set, including the filter element and the cup, are removed from the column. "FILTER CUP AND METHOD FOR MANUFACTURING THE SAME" The present invention relates to a filter cup (8). The filter cup (8) includes an elongated container having an open end (16), a closed end and a wall having an outer surface (26), the outer surface having a plurality of laminated threads (24). The outer surface (26) includes a non-threaded portion (28) located between the open end (16) and the plurality of laminated threads (24). The filter cup (8) is preferably made of steel and is produced in a process that includes the steps of: 1) deep drawing of the elongated container, and 2) lamination of the threads on the outer surface of the container.
