摘要： A valve assembly for permitting fluid flow in a first direction and for preventing fluid flow in a second direction opposite to the first direction. The valve assembly includes an upper housing, a lower housing coupled to the upper housing to form a generally axially extending housing assembly, and a valve seating section defined within an inner peripheral portion of the lower housing. The valve seating section includes an axially extending inner peripheral surface and a transversely extending surface substantially normal to the axially extending inner peripheral surface. A valve member is seated within the valve seating section of said lower housing. The valve member includes a flange that extends from the valve member in a transverse direction and defines an axially oriented outer peripheral surface thereof. The valve member is retained within the valve seating section of the lower housing by the axially extending inner peripheral surface of the valve seating section transversely compressing the axially oriented outer peripheral surface of the flange to form a press-fit therebetween. Further, the valve member also includes a lower transverse surface which is axially separated from the transversely extending surface of the valve seating section, in which an air space is defined between these two transverse surfaces.
摘要翻译： 一种阀组件，用于允许流体在第一方向上流动并且用于防止流体沿与第一方向相反的第二方向流动。 阀组件包括上壳体，下壳体，其联接到上壳体以形成大致轴向延伸的壳体组件，以及限定在下壳体的内周部分内的阀座部分。 阀座部分包括轴向延伸的内周表面和基本上垂直于轴向延伸的内周表面的横向延伸表面。 阀构件位于所述下壳体的阀座部分内。 阀构件包括从阀构件沿横向延伸并限定其轴向定向的外周表面的凸缘。 阀构件通过阀座部分的轴向延伸的内周表面横向地压缩凸缘的轴向定向的外周表面而保持在下壳体的阀座部分内，以在其间形成压配合。 此外，阀构件还包括与阀座部分的横向延伸表面轴向分离的下横向表面，其中在这两个横向表面之间限定空气空间。
