ABSTRACT:
A speed controller has a pilot check valve having a first body which has a first fluid inlet/outlet port defined in an end thereof and a pilot port defined in an opposite end thereof. A flow control valve has a second body integral with the first body. A pipe joint has a third body which has a second fluid inlet/outlet port defined in an end thereof and, the third body being integral with the second body. A flow adjustment screw is disposed in the flow control valve and extends into a fluid passage which interconnects the first fluid inlet/outlet port and the second fluid inlet/outlet port, for adjusting a rate of flow of a fluid under pressure in the fluid passage. A valve body is disposed in the pilot check valve for opening a fluid passage which interconnects the first fluid inlet/outlet port and the second fluid inlet/outlet port in response to a pilot fluid pressure supplied from the pilot port.
