ANORDNING FOR ANSLUTNING AV EN TRYCKFLUIDKELLA TILL EN FORBRUKARE |
摘要 |
<p>A device for connecting a hydraulic pump or other pressure fluid source to a working cylinder or other fluid motor comprises a pair of concentric hoses and a safety shut-off valve. One end of the inner hose is connected to the cylinder and the other end is connected to the pump by way of the safety shut-off valve. The space between the hoses normally is unpressurized and is in constant communication with a cavity containing a movable element of the shut-off valve. An elevated pressure in the space between the hoses will actuate the valve element for closing the shut-off valve. A second valve element is movable to close the valve when subjected to fluid flow forces resulting from an excessive flow of hydraulic liquid through the shut-off valve.</p> |
