다이아프램 및 밀봉 셸 결합부Diaphragm and Sealed Shell Joints

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 개량된 다이아프램을 지지하는 하우징을 포함하며, 그러한 하우징을 형성하여 내부에 개량된 다이아프램을 합체한 밀봉 셸 결합부를 얻는데 사용되는 브레이크 부스터를 도시한 단면도.1 is a cross-sectional view of a brake booster comprising a housing for supporting the improved diaphragm of the present invention and used to form such a housing to obtain a sealed shell joint incorporating the improved diaphragm therein.

제2a도는 본 발명의 기본적인 구성부품을 형성하는 개량된 다이아프램의 외주부와 셸 돌기의 확대단면도.Figure 2a is an enlarged cross-sectional view of the outer periphery of the improved diaphragm and shell projection forming the basic components of the present invention.

제2b도는 종래 기술에 따라 밀봉 셸 결합부에 의해 형성된 브레이크 부스터의 밀봉 셸 하우징의 기본적인 구성 부품을 도시한 확대단면도.2b is an enlarged cross-sectional view showing the basic components of the sealed shell housing of the brake booster formed by the sealed shell engaging portion according to the prior art.

Claims (2)

제1 및 제2셸에 의해 형성된 하우징에 대하여 유체밀봉실을 형성해주기 위해 제1 및 제2셸 사이에 외주모서리가 끼워진 다이아프램으로서, 상기 제1셸은 그 개구단에 방사상으로 단이 진 확대직경부를 갖는 컵 형상으로 되어 있고, 상기 제2셸은 일반적으로 상기 제1셸의 방사상으로 단이 진 확대직경부에서의 내경에 일치하는 외경을 갖고 외주 모서리가 그 외주 모서리에 인접하여 상기 제1셸의 방사상으로 단이 진 확대직경부재에 방사내향으로 돌출하기 위한 되접혀진 환형 돌기에서 끝나는 원판 형태로 되어 있으며, 상기 다이아프램은 두꺼운 외주부와 상기 환형돌기를 받아들이기 위해 상기 환형돌기에 대응하는 크기 및 위치를 갖고 상기 외주부의 표면내에 형성되는 환형홈을 포함하므로써, 상기 밀봉된 하우징을 형성하기 위한 제1 및 제2셸의 결합을 이룰 수가 있고 각각의 셸의 외주를 함께 결합해주는 압압력에 불균형이 있다 할지라도 상기 다이아프램이 상기 셸들에 대해 변위되지 않도록 상기 다이아프램의 두꺼운 외주부에 있는 환형홈내에 제2셸의 환형 돌기를 끼워 맞추어서 제1 및 제2셸 사이에 상기 다이아프램의 두꺼운 외주부가 삽입될 수 있게 한 것을 특징으로 하는 다이아프램.A diaphragm having an outer circumferential edge interposed between the first and second shells to form a fluid sealing chamber with respect to the housing formed by the first and second shells, the first shell being radially extended at its open end. The second shell is generally in the shape of a cup having a diameter, and the second shell generally has an outer diameter corresponding to the inner diameter at the radially extended enlarged diameter portion of the first shell, and an outer peripheral edge thereof is adjacent to the outer peripheral edge thereof. It is in the form of a disc ending in a retracted annular projection for radially protruding radially extended enlarged diameter member of the shell, wherein the diaphragm is of a size corresponding to the annular projection for receiving a thick outer periphery and the annular projection. And an annular groove having a position and formed in the surface of the outer circumferential portion, thereby forming the first and second shells for forming the sealed housing. Annular projection of the second shell in an annular groove in the thick outer periphery of the diaphragm so that the diaphragm is not displaced with respect to the shells, even if there is an imbalance in the pressing force that can be combined and the outer periphery of each shell The diaphragm characterized in that the thick outer peripheral portion of the diaphragm can be inserted between the first and second shell by fitting a. 브레이크 부스터등의 하우징을 한정해주는 제1 및 제2셸 사이의 개량된 밀봉 셸 결합부에 있어서, 상기 하우징은 개구단에 방사상으로 단이 진 확대직경부를 갖는 컵형상으로 된 제1셸과, 상기 제1셸의 방사상으로 단이 진 확대 직경부에서의 내경에 대략 일치하는 직경으로 된 외주 모서리를 갖고 외주 모서리에 인접하여 방사내향으로 돌출하는 되접혀진 환형 돌기에서 끝나는 원판 형태의 제2셸 및 상기 제1셸의 확대 직경부에서의 내경에 대략 일치하는 직경으로 된 두꺼운 외주부와 상기 제2셸의 환형 돌기에 대응하는 크기 및 위치를 갖고 상기 돌기에 마주하여 상기 돌기를 받아들이도록 상기 다이아프램의 두꺼운 외주부 표면내에 형성되는 환형홈을 포함하며 상기 결합된 제1 및 제2셸 사이에 기밀 밀봉을 제공하면서 각각의 측부에 상기 하우징을 위한 유체밀봉실을 한정해주는 다이아프램으로 구성된 것을 특징으로 하는 밀봉 셸 결합부.In an improved sealing shell joint between a first shell and a second shell defining a housing such as a brake booster, the housing includes a cup-shaped first shell having an enlarged diameter portion radially extended at the open end; A second shell in the form of a disc having an outer circumferential edge with a diameter approximately coincident with the inner diameter at the radially extended enlarged diameter portion of the first shell and ending in a retracted annular projection protruding radially inward adjacent to the outer circumferential edge; A thick outer periphery having a diameter approximately equal to the inner diameter at the enlarged diameter portion of the first shell and a size and a position corresponding to the annular protrusion of the second shell, the thick of the diaphragm receiving the protrusion opposite to the protrusion.
