ARTICULATED HOSE FOR TRANSFER OF LIQUID MEDIUM WITH SPRING BALANCING AT LARGE ANGLE DEFLECTION Russian patent published in 2004 - IPC

FIELD: materials handling facilities.

SUBSTANCE: proposed hose has two branches interconnected by swivel joint with horizontal axle. One of branches made for rotation has angular working position in which it is in equilibrium despite action of gravity force. Balancing device compensates for changes in gravity force action onto movable branch depending on direction of the latter relative to vertical. Said balancing device is installed between fixed working part and connecting section of movable branch is kept at constant distance from axis of rotation other than zero, and is provided with spring. Said spring keeps movable branch in its working angular position, and in this case spring is at rest, acting onto movable branch with force proportional to distance between connecting section and place of connecting section when it is in working angular position.

EFFECT: provision of reliable balancing, small size and low cost of device.
