摘要： A mass flow controller having a shut off valve in a flow path body as an integral part. The mass flow controller minimize a dead space between the shut off valve and a mass flow control valve to reduce the amount of entrapped gas therein, thereby avoiding occurrence of overshoot in the initiation of the next mass flow control operation. In another aspect, a bypass passage is provided in the flow path body. The bypass passage bypasses a sensor flow path, a bypass flow path and a mass flow control valve which increase a flow resistance, and therefore, a large amount of purge gas can be passed through the bypass passage in a short time. In still another aspect, a sealing surface of a valve seat is made into coplanar with the top surface of the flow path body, thereby making the sealing surface and the top surface of the body possible to be simultaneously subjected to lapping finish. This enhances the parallel relation between the sealing surface and the top surface of the body and makes it easy to align the axis of an actuator with the axes of other parts.

摘要翻译： 一种质量流量控制器，其具有作为一体部分的流路主体中的截止阀。 质量流量控制器最小化截止阀和质量流量控制阀之间的死区，以减少其中的夹带气体的量，从而避免在下一个质量流量控制操作的启动中发生过冲。 在另一方面，在流路主体中设置有旁路通路。 旁通通道绕过传感器流路，旁通流路和质量流量控制阀，其增加流动阻力，因此可以在短时间内大量吹扫气体通过旁通通道。 另一方面，将阀座的密封面与流路主体的上表面共面，由此能够使密封面和主体的上表面同时进行研磨。 这增强了密封表面和主体顶表面之间的平行关系，并且使得致动器的轴线与其他部件的轴线对准变得容易。
