    • A serviceable valve is provided for controlling the recirculation of exhaust gases within an internal combustion engine. The valve includes a housing having a first section provided with an interior chamber and a second section secured to and subtending said first section. A diaphragm is affixed to and interposed the housing sections and is in communication with the chamber. In response to a predetermined chamber pressure, the diaphragm is distorted in one direction from a predetermined rest position. The housing is mounted on a fitting, which subtend the housing second section, whereby said housing and the diaphragm are rotatable as a unit about an axis of the fitting to selected positions of adjustment. The fitting is removably mounted on the engine. Carried on the diaphragm is a stem assembly which is movable longitudinally in response to the distortion of the diaphragm. A portion of the stem assembly extends through and protrudes from the fitting and has a valve piece mounted thereon. The valve piece is adapted to coact with a valve seat disposed within a recirculation flow path of the engine exhaust gases and, when seated thereon, blocks recirculation of the exhaust gases through the engine. The housing first section is provided with a port offset from the fitting axis and adapted to be removably connected to a pressure fluctuating segment of the engine. Means is provided which coacts with the fitting and the housing second section and releasably retains the housing and diaphragm in a selected position of adjustment relative to the fitting.
    • 提供了一种用于控制内燃机内废气再循环的可使用阀。 所述阀包括壳体,所述壳体具有设置有内部腔室的第一部分和固定到所述第一部分并对向所述第一部分的第二部分。 隔膜被固定到壳体部分并插入壳体部分并且与腔室连通。 响应于预定的室压力,隔膜在预定的静止位置沿一个方向变形。 壳体安装在配件上,该配件对着壳体第二部分,由此所述壳体和隔膜作为围绕配件的轴线的单元可旋转到选定的调整位置。 该配件可拆卸地安装在发动机上。 在隔膜上进行的是可以响应于隔膜的变形而纵向移动的杆组件。 杆组件的一部分延伸穿过配件并从配件突出并且具有安装在其上的阀片。 阀片适于与设置在发动机废气的再循环流动路径内的阀座共同作用,并且当其位于其上时,阻止废气通过发动机的再循环。 壳体第一部分设置有从配合轴线偏移的端口并且适于可移除地连接到发动机的压力波动部分。 提供了与配件和壳体第二部分共同作用并且将壳体和隔膜可释放地保持在相对于配件的选择调整位置的装置。
