| 專利摘要 | 本創作揭露一種複合型薄膜節流器，其係包含殼體、本體、節流構件、以及彈性薄膜。殼體具有來源端、負載端以及第一容置空間。本體設置於第一容置空間，並具有第二容置空間、第三容置空間以及第一引流道。節流構件設置於第三容置空間，與本體形成穩壓腔室以及調節腔室，並具有內孔。彈性薄膜設置於本體與節流構件之間以與節流構件形成間隙。工作流體之第一分流係由第一引流道流入調節腔室，並通過間隙與內孔流至負載端。當工作流體於負載端之流動壓力增加時，彈性薄膜係受工作流體壓迫而使間隙增加，藉以調節負載端之流動壓力。 The invention discloses a composite thin film throttle including a housing, a body, a throttle member, and an elastic film. The housing includes a source end, a loading end, and a first accommodating space. The body is disposed in the first accommodating space and includes a second accommodating space, a third accommodating space, and a first channel. The throttle member, disposed in the third accommodating space, forms a stabilizing pressure chamber and an adjusting chamber with the body and has an inner hole. The elastic film is disposed between the body and the throttle member to form a gap with the throttle member. A first split flow of a working fluid flows to the adjusting chamber from the first channel, and then flows through the gap and the inner hole to the loading end. When the pressure of the working fluid increases at the loading end, the elastic film will be pressed by the working fluid to increase the gap, so as to adjust the pressure at the loading end. |
