摘要： A flow rate control apparatus is provided which enables high speed response particularly in a transient response state, such as when a target flow rate falls. The flow rate control apparatus includes: a valve provided with a position sensor to measure an opening degree and disposed in a flow channel; a flow rate sensor disposed upstream of the valve and provided with a restrictor; a first pressure sensor disposed downstream of the restrictor and disposed upstream of the valve; a second pressure sensor disposed downstream of the valve; a storage section to store a characteristic map indicating a relationship between at least the opening degree of the valve, a differential pressure before and after the valve, and a flow rate of a fluid passing through the flow channel; and a valve control section to control the valve so that the flow rate reaches an accepted target flow rate.

摘要： The fluid mixing element in accordance with this invention forms a first internal flow channel whose starting end opens on an end surface of one end part and whose terminal end opens on an end surface of the other end part and a second internal flow channel whose starting end opens on a side peripheral surface of a middle part and whose terminal end opens on an end surface of the other end part. It is possible for the fluid mixing element to securely mix a first fluid flowing in a main flow channel with a second fluid flowing in a sub-flow channel by the use of a pipe with a short length with a simple arrangement.

摘要： To provide a fluid control valve that enables the internal volume to be reduced and, for example, the falling response performance to be improved without compromising the accuracy in controlling a pressure, a flow rate, and so on of fluid, a fluid control valve includes a valve seat portion, a valve body capable of making or breaking contact with the valve seat portion, a fluid resistance, and a pair of clamping members that clamps the fluid resistance. The fluid resistance and the pair of clamping members form an in-valve space in which the valve body or at least part of an actuation member that moves the valve body is housed. Fluid passes through the fluid resistance from the downstream-side in-valve space and flows out to the outside.
