Claims

[Scope of utility model registration request]

A flow rate control spool is installed in the housing, and a valve body separate from this flow rate control spool is installed, and the valve body is moved according to the differential pressure before and after the fixed throttle.
In a flow rate control device that controls the flow rate, a valve body is installed in the housing, a valve body with a fixed throttle is installed inside the valve body, a metering orifice is formed in the valve body, and a metering orifice is formed in the valve body. While communicating the port and the secondary port via a fixed throttle and a metering orifice,
The flow rate control device is configured to throttle the opening of the metering orifice when the valve body moves according to the differential pressure before and after the fixed throttle, and the valve body and the valve body together form a damper chamber.
