A compact fluid pressure regulation valve includes a valve body, the valve body having a pair of passageways, one passageway being a fluid pressure regulating passageway and the other passageway being a high pressure fluid supplying passageway. The fluid supplying passageway extends substantially perpendicular to the pressure regulating passageway and has a downstream end which opens to an upstream portion of the pressure regulating passageway. The fluid supplying passageway has on and off modes for supplying high pressure fluid to the pressure regulating passageway. A device is provided for activating the fluid supplying passageway from an off mode to an on mode. Further, a device is provided within the pressure regulating passageway for utilizing pressure within this passageway as a back pressure to regulate the pressure of the fluid flowing therethrough. With this arrangement a very compact fluid pressure regulation valve is provided.
