Description
"DISPOSIÇÃO EM PEÇA FÊMEA DE ENGATE RÁPIDO""FAST HITCH FEMALE PIECE"
O presente modelo de utilidade refere-se a uma inovadoradisposição construtiva introduzida em peça fêmea de engate hidráulico paraacoplamento rápido.The present utility model relates to an innovative constructive arrangement introduced in a female quick coupler hydraulic coupling.
empregadas para o acoplamento das peças machos (pinos), geralmenteacoplados nas extremidades de mangueiras. Um exemplo de peça fêmeaconvencional é descrito no documento de patente MU 8500833-8, do mesmoinventor e ilustrada nas figuras 1 a 4, que compreende um corpo (20) formadopor um suporte roscado (21), uma luva intermediária (22) e uma luva externa(23). O suporte (21) é roscado na máquina ou implemento onde o engate fêmeaé instalado. No interior desse corpo (20) está montado um conector (24) queacolhe uma peça macho, não ilustrada. No interior conector (24) está montadauma válvula (25) que impede a saída do óleo quando do acoplamento oudesacoplamento da peça macho. Essa válvula (25) é parcialmente montada nointerior de uma sede cilíndrica (28) e se mantém constantemente fechada porforça de uma mola. Quando da introdução da peça macho no interior do engate(20) o conector (24) recua arrastando a peça cilíndrica (28). Para evitar ageração de pressão interna, o que dificultaria o acoplamento da peça macho, éexecutado um orifício de alívio de pressão (26) no suporte roscado (21) docorpo da peça fêmea. Esse orifício (26) é executado diagonalmente, de modo acomunicar a câmara de ar (27), existente no fundo da peça cilíndrica (28), como exterior. Entretanto, para impedir a entrada de sujeira e material particuladono interior do corpo da peça fêmea é empregado um anel de vedação (30) emum sulco periférico profundo (29) que é usinado na porção de parede espessado suporte roscado (21).employed for the coupling of male parts (pins), generally coupled to the ends of hoses. An example of a conventional female part is described in patent document MU 8500833-8 of the same inventor and illustrated in Figures 1 to 4, comprising a body (20) formed by a threaded support (21), an intermediate sleeve (22) and a sleeve external (23). The bracket (21) is threaded into the machine or implement where the female coupling is installed. Within this body (20) is mounted a connector (24) housing a male part, not shown. Inside the connector (24) is mounted a valve (25) that prevents oil from escaping when coupling or uncoupling the male part. This valve (25) is partially mounted on the inside of a cylindrical seat (28) and is constantly closed by a spring. Upon insertion of the male part into the coupling (20) the connector (24) recedes by dragging the cylindrical part (28). To prevent internal pressure build-up, which would make it difficult to engage the male part, a pressure relief hole (26) is drilled in the threaded support (21) of the female part body. This orifice (26) is made diagonally so as to make the inner tube (27), which is at the bottom of the cylindrical part (28), as exterior. However, to prevent dirt and particulate matter from entering the female part body, a sealing ring (30) is employed in a deep peripheral groove (29) that is machined into the thickened threaded support wall portion (21).
Esse anel de vedação (30) para peça fêmea de engatehidráulico rápido resulta nos seguintes inconvenientes:This sealing ring (30) for quick coupler female part results in the following drawbacks:
• possui uma seção transversal complexa, em forma de "T", sendo fabricadoespecial e exclusivamente para essa finalidade;• has a complex T-shaped cross-section, being manufactured specifically and exclusively for this purpose;
• demanda um sulco (29) profundo para poder acomodar a perna do anel devedação (30), exigindo que o suporte roscado (21) seja usinado a partir de• requires a deep groove (29) to accommodate the sealing ring leg (30), requiring the threaded support (21) to be machined from
As peças fêmeas dos engates rápidos conhecidos sãouma barra cilíndrica de maior diâmetro, sob pena de restar uma espessuramuito fina, pois o seu posicionamento coincide com um sulco interno;The female parts of the known quick couplers are a larger diameter cylindrical bar, otherwise a very thin thickness will remain because their positioning coincides with an internal groove;
• exige que o sulco (29) seja de grande largura, pois deve acolher a cabeça doanel de vedação (30), demandando maior volume de usinagem do suporteroscado (21);• requires the groove (29) to be wide, as it must accommodate the sealing ring head (30), requiring greater machining volume of the supporteroscope (21);
• o canal de alívio de pressão (26) é inclinado, o que dificulta o seuposicionamento preciso e exige um dispositivo especial para guiar ausinagem.• The pressure relief channel (26) is angled, which makes it difficult to position accurately and requires a special device to guide the sounding.
É, portanto, objetivo do presente modelo de utilidade umainovadora disposição construtiva introduzida em peça fêmea de engatehidráulico rápido que supera eficazmente as referidas limitações do estado datécnica. A nova disposição compreende uma peça fêmea, cujo suporte roscadoé dotado de um orifício executado longitudinalmente, destinado a comunicar acâmara de ar existente no fundo da sede cilíndrica interna com um sulcoperiférico não profundo que é executado em porção espessa da parede docorpo da peça. No interior do sulco raso está embutido totalmente um anel deseção circular que veda o orifício, impedindo a entrada de material particuladoexterno para o interior da peça fêmea.It is therefore the objective of the present utility model an innovative constructive arrangement introduced in a quick coupler female part that effectively overcomes the said limitations of the technical state. The new arrangement comprises a female part, the threaded support of which is provided with a longitudinally-directed hole, for communicating the air chamber at the bottom of the inner cylindrical seat with a non-deep groove running in a thick portion of the body wall of the part. Within the shallow groove is a fully enclosed circular ring that seals the hole, preventing external particulate material from entering the female part.
A disposição construtiva introduzida em peça fêmea deengate rápido hidráulico, proposta pelo modelo de utilidade, resulta nasseguintes vantagens sobre os engates convencionais:The constructive arrangement introduced in the hydraulic quick coupler female part, proposed by the utility model, results in the following advantages over conventional couplings:
• o anel de vedação é de seção transversal circular, tradicionalmente fabricadopara outras finalidades, sendo abundante no mercado e facilmente adquirido;• the sealing ring is of circular cross section, traditionally manufactured for other purposes, being abundant in the market and easily purchased;
• o sulco é raso, devido à forma do anel de vedação que nele é embutido,permitindo que o suporte roscado seja usinado a partir de uma barracilíndrica de menor diâmetro;• The groove is shallow due to the shape of the sealing ring which is embedded in it, allowing the threaded support to be machined from a smaller diameter barrel;
• o sulco é estreito, pois o anel de vedação é circular, reduzindo o volume deusinagem no suporte roscado;• The groove is narrow, as the sealing ring is circular, reducing the volume turning on the threaded support;
• o canal de alívio de pressão é longitudinal, o que facilita a sua usinagem.• The pressure relief channel is longitudinal, which facilitates its machining.
